The steps at which the specific kind of RNA plays role is determined by the information carried by the RNA for several cellular processes.
The process of transcription and RNA processing is done by mRNA (messenger RNA). Translation is done by tRNA (Transfer RNA) and rRNA (Ribosomal RNA). During replication, a same copy of a DNA molecule is produced while during transcription, the DNA sequence is copied onto a molecule of mRNA. Translation is the process by which RNA produces proteins of specific kind. The information about the kind of protein is given by mRNA. Ribonucleic acid is a nucleic acid present in all living cells which is structurally similar to DNA but is single stranded in nature and is primarily responsible for synthesis of proteins.

Individuals with pku tend to have high levels of _______ in their blood because they have an inactive variant of an _______.
People with PKU cannot break down the amino acid phenylalanine, which then accumulates in the blood and brain. This can lead to brain damage.
Phenylketonuria (commonly known as PKU) is an inherited disorder that increases the levels of a substance called phenylalanine in the blood. Phenylalanine is a building block of protein (an amino acid) that is obtained through the diet. It is found in all proteins and some artificial sweeteners.
Patients with phenylketonuria (PKU) have a diet-controlled deficiency in the conversion of phenylalanine (Phe) to tyrosine (Tyr), leading to decreased production of norepinephrine, adrenaline, and dopamine.
A genetic change (genetic mutation) causes PKU, which can be mild, moderate, or severe. In a person with PKU , a change in the phenylalanine hydroxylase (PAH) gene causes a lack or reduced amount of the enzyme needed to process phenylalanine, an amino acid.

The image shows homologous chromosomes with different alleles, sister chromatids always have the same alleles and gene A is at the same locus On all four chromatids.
One chromosome from a pair that shares the same gene sequence, loci, chromosomal length, and centromere is referred to as a homologous chromosome. One chromosome from the father and one from the mother make up a homologous pair.
A sister chromatid is one that has two identical copies of a chromosome that are connected by a common centromere during chromosome DNA replication. In other words, a sister chromatid can also be thought of as "one-half" of a chromosome that has been duplicated. A dyad is a pair of sister chromatids. When all of the chromosomes in a cell are replicated during the synthesis (S) phase of interphase, a full pair of sister chromatids is produced. During mitosis or the second division of meiosis, the two sister chromatids split apart into two distinct cells.

two students decided to repeat the hershey and chase experiment, with modifications. like hershey and chase they used radioactive sulfur but they substituted radioactive nitrogen for radioactive phosphate. they reasoned that each nucleotide has only one phosphate and two to five nitrogen atoms. thus, labeling the nitrogen atoms would provide a stronger signal than labeling the phosphates. which of the following is the biggest shortcoming in their experimental design?
The biggest shortcoming in their experimental design is that nitrogen is present in both proteins and DNA.
The goal of the Hershey and Chase experiments was to establish if the hereditary material is protein or DNA. They employed bacteriophages that contained radioactive phosphorous and sulfur. They discovered that the progenies generated after bacteria were infected, exclusively contained radioactive phosphorous. They chose radioactive phosphorus and sulfur as proteins don't have phosphorus, and DNA doesn't have sulfur.
The experiment that is being proposed has a number of flaws, but the most significant one is that nitrogen is present in both proteins and DNA. As a result, if radioactivity is found in progeny phages, we will not be able to distinguish whether it originated from DNA or protein.

Suppose that for a certain gene, nearly 100 percent of the normal level of expression is required to produce the normal phenotype. Based on this requirement, one could predict that a loss of function mutation would be recessive.
What is a gene?
The fundamental physical and functional unit of heredity is a gene. DNA constitutes genes. A chromosome is a lengthy DNA strand with numerous genes on it.
The relationship between two variants of a gene is described as dominant. Every gene has two different variations, or alleles, that an individual inherits from each parent. One allele will be expressed when there are different alleles of a gene; this allele is the dominant gene. Recessive, the other allele, has little or no effect.
Alleles with wild types often code for a substance required for a particular biological process. The function that it encodes for is also lost if a mutation arises in that allele. These mutations are known as loss-of-function mutations in general. The function can be lost to varying degrees. A null mutation is one in which the function has completely disappeared. It's also conceivable that some function might endure, but not to the same degree as the wild type allele. They are referred to as leaky mutations.
Mutations that cause loss of function are often recessive. When the wild-type allele and the loss-of-function allele are heterozygotes, the level of expression of the wild-type allele is frequently enough to produce the wild-type phenotype. This would categorize the loss-of-function mutation as recessive in terms of genetics. On the other hand, the wild type allele might not make up for the loss-of-function allele. In those situations, the heterozygote's phenotype will be identical to that of the loss-of-function mutant, and the mutant allele will take the role of the dominant allele.

if neonicotinoids bind to the acetylcholine receptors stoping the channels from opening what happens to the nerve impulse?
If neonicotinoids bind to the acetylcholine receptors stoping the channels from opening it will induce neuronal depolarisation and temporarily prevent the action of acetylcholine.
Neuronal depolarization relies upon on the hole of ion channels withinside the neuronal membrane and the following inflow of sodium ions (Na+) and efflux of potassium ions (K+). Neuronal responses to ion channel receptor activation by natural ligands/neurotransmitters or drugs are rapid and brief.
During depolarization, the cell's internal negative charge temporarily becomes more positive (less negative). This shift from negative to more positive membrane potential occurs during several processes, including action potentials.
Neonicotinoids bind to acetylcholine receptors on the post-synaptic membrane of insect cholinergic synapses. Because cholinesterase does not break down the pesticide, it remains bound to its receptors, preventing the binding of acetylcholine.This blocks synaptic transmission that kills insects.

a woman who has blood type a positive has a daughter who is type o positive and a son who is type b negative. rh positive is a trait that shows simple dominance over rh negative and is designated by the alleles r and r, respectively. a third gene for the mn blood group has codominant alleles m and n. which of the following is a possible phenotype for the father?
A third gene for the MN blood group has codominant alleles M and N. This means that the father of the children must have at least one R allele, one M allele, and one N allele. Therefore, a possible phenotype for the father would be blood type A positive, Rh positive, MN positive.
In order to determine the father’s genotype, we must look at the genotypes of the mother and the two children. Since the mother is type A positive, she must have two A alleles and two R alleles (AO and Rr). The daughter is type O positive, which means she has two O alleles and two R alleles (OO and Rr). The son is type B negative, which means he has two B alleles and two r alleles (BB and rr).
From this information, we can deduce that the father must have at least one A allele, one B allele, and two R alleles. Therefore, the possible genotypes for the father can be AO and Rr, BO and Rr, AB and Rr, or AB and RR. All of these genotypes would result in a phenotype of blood type A positive, Rh positive, MN positive.
In conclusion, a woman who has blood type A positive and two children with different blood types (O positive and B negative) could have a father with a phenotype of blood type A positive, Rh positive, MN positive. The possible genotypes for the father in this situation would be AO and Rr, BO and Rr, AB and Rr, or AB and RR.
