The genetic code is defined degenerate or even redundant because:
A. the same codon codes for different amino acids
B. an amino acid can be encoded by several codons
C is different in all organisms, except in monozygotic twins
D. the sequence of codons is not separated by intervals, but is continuous
E. the structure of the genes is constantly mutating
Answer:
B. an amino acid can be encoded by several codons
Explanation:
The genetic code refers to the set of rules that govern how the four nitrogenous bases (A,U,G,C) is arranged to form amino acids. The genetic code is a collection of all the CODONS formed. There are different characteristics of the genetic code and one of them is its REDUNDANCY.
Since there are 4 nitrogenous bases combined in three's to form a codon i.e. 4³, there are 64 possible codons that could form 20 maximum amino acids. This means that there are more codons in relation to amino acids. Hence, more than one codon can encode an amino acid, and this is referred to as REDUNDANCY of the genetic code.
For example, LEUCINE amino acid is encoded by 6 codons as follows: UUA, UUG, CUU, CUC, CUA, CUG.

If ball C is 3 times the volume of ball D and ball D has 1/3 the mass of ball C, which has the greater density?
If two balls have the same mass, but ball P is twice as large as ball Q, which one will have the greater density?
If ball X is twice as big as ball Y and weighs only half as much as ball Y, then which one will have the greater
density?
mious Activity
Answer:
Ball A has more density.
Explanation:
Density is found using mass divided by volume. Let's say ball A has a mass of 6 grams, and ball B has a mass of 3 grams. If the volume for both is 1 mL, then ball A has more density.
Senario: 2 years ago, a fruit was smuggled into California on a plane from an exotic, far away land. The homeowner saw that the fruit had maggots and tossed it into the backyard, hoping the seed would grow. The larvae hatched out and moved throughout the area. This fictitious insect will destroy fruit and has the possibility of spreading disease killing the trees. The insect consumes plants in the Prunus species of stone fruits? Look up the plant genus Prunus.
Discussion: The insect has spread over a large area of Southern California, discovered at UC Riverside. What steps would you do to control or eradicate the destructive exotic insect?
Answer:
To destroy this insect, a chemical should be used or made that will fight the main power of the insect. Also the food that is targeted should be removed.

The ability of the human body to break down the red color in beets is controlled by an autosomal dominant allele. The inability is recessive, detected by red coloration of the urine (we will call this phenotype 'secretor'). If a nonsecretor woman with a secretor father has children with a nonsecretor man who in a previous relationship had a secretor daughter, what is the probability that their first child will be...
Solution :
It is given that a woman is a nonsecretor but the father of that woman is a secretor. It means that the father's genotype is recessive, i.e. "ss".
The genotype of the nonsecretor mother would be Ss, who have received one recessive allele from her father.
Now the nonsecretor man have a secretor daughter from his previous marriage. That means that he is a carrier nd his genotype is Ss.
Now, we can cross between the heterozygous parents (Ss x Ss) will have offspring with the following genotypes :
1 SS -- Nonsecretor
2 Ss -- Nonsecretor
1 ss -- secretor
Thus the probability that their first child will be :
a). a secretor girl
[tex]$=\frac{1}{4} \times \frac{1}{2}$[/tex]
[tex]$=\frac{1}{8}$[/tex]
b). Non secretor girl

How does penicillin kill bacteria? Penicillin augments the body's natural ability to enzymatically degrade bacterial peptidoglycan, causing the cells to lyse Penicillin targets a cross-linking reaction in cell wall manufacture. By blocking the enzyme responsible, penicillin stops the bacteria from producing new peptidoglycan. Penicillin targets muramic acid in the cell wall. By damaging a key component of the cross-linking reaction, the cell can't build a strong peptidoglycan mesh and quickly breaks apart. Penicillin damages the lipid membrane of bacterial cells by enzymatically removing peptidoglycan from the membrane's outer surface. The weakened cells quickly lyse.
Answer:
The correct answer is option c. By blocking the enzyme responsible, penicillin stops the bacteria from producing new peptidoglycan.
Explanation:
Penicillins are derived from Penicillium molds. These are a group of antibiotics, used in treating various types of bacterial infections such as urinary tract infections, respiratory tract infections, gastrointestinal infections etc.
These antibiotics also used in treating gonorrhoea, meningitis, pneumonia, syphilis, etc. These antibiotics stop the bacteria from producing new peptidoglycan that blocks the enzyme.

The predominant forms of actin inside a cell are ATP-G-actin and ADP-F actin. What would be the consequence for actin filament assembly/disassembly if a mutation prevented actin's ability to bind ATP
Answer:
If actin is unable to bind to the ATP molecule, it will not be able to assemble into its two dominant forms.
Explanation:
As shown in the question above, the two predominant forms of actin are ATP-G-actin and ADP-F actin. As we can see, the formation of these two molecules involves the presence of an ATP molecule, in which case, the concentration of actin inside an organism depends totally on the capacity of the actin to be able to bind to an ATP molecule. If there is a mutation that prevents this binding from occurring, actin will not be able to form its two dominant forms, which will harm the presence of actin in the body.

Individuals with premutation length repeats in FMR1 may have some of the phenotypes of Fragile X but not others, which is _____________; for example, some individuals may have cognitive deficiencies, while others might have late onset ataxia. In addition, some individuals will have no phenotypes of the condition at all, due to ____________.
Answer:
variable expressivity; incomplete penetrance
Explanation:
In genetics, variable expressivity refers to the fact that individuals having the same alleles/genes/genotype associated with a particular genetic condition may exhibit different clinical features of this condition. In general, variable expressivity is due to the combination of both genetic and environmental factors. An example of variable expressivity is the Marfan syndrome, where all individuals with this disorder have a dominant mutation in the FBN1 (fibrillin 1) gene and show different degrees of the same phenotype. Moreover, incomplete penetrance (also known as reduced penetrance) refers to the complete absence of a genetic trait or disease in individuals having alleles/genes/genotype associated with the condition. In consequence, individuals with incomplete penetrance do not develop features of the disease. An example of incomplete penetrance is given by those individuals with mutations in BRCA1/BRCA2 genes (associated with an increased risk of developing breast cancer) that do not develop cancer.

A plant of genotype C/C ; d/d is crossed to c/c ; D/D and an F1 testcrossed to c/c ; d/d. If the genes are linked, and 20 map units apart, what will be the percentage of c/c ; d/d recombinants
Answer:
10%
Explanation:
The parental crossings = Cd/Cd x cD /cD
The distance the genes C and D = 20 map units
Determine the percentage of cd / cd recombinants that will be formed
the distance shows that there is only 20% recombinant progeny
The recombinants are : CD/CD and cd/cd = 20%
i.e. each recombinant progeny = 20% / 2 = 10%
hence % of cd/cd recombinant = 10%

What is the ethical dilemma associated with randomized controlled studies for suspected causes of disease such as cigarette smoking?
a. The prevalence of disease within the study cannot be controlled.
b. The effect of the disease is too detrimental to the health of those involved within the study to allow them to be voluntarily exposed to a suspected cause of disease.
c. Incidence of disease is often determined to be too low to conduct a randomized controlled trial.
d. It is difficult to establish definitive contributory cause even with a high-quality randomized controlled trial.
Answer:
b. The effect of the disease is too detrimental to the health of those involved within the study to allow them to be voluntarily exposed to a suspected cause of disease.
Explanation:
Randomized controlled studies assess the relationship between cause and effect. There are usually two groups in this study. The first group is the experimental group which is exposed to the treatment or intervention to be assessed while the second group is the control group which is given no treatment or given a placebo.
As it relates to the question, the experimental group is exposed to cigarettes to determine the effect of this exposure. This can have an adverse health effect on the experimental group, hence, this is an ethical dilemma.
