The trp and lac operons are regulated based on presence of tryptophan and lactose respectively.
The Lac Operon model can be used to describe how prokaryotic genes are regulated. Here, it is possible to see how changes in physiology and the environment affect prokaryotes' ability to express certain genes. Monod and Jacob were present and saw it. Genes aid in the metabolism of lactose. Lactose functions as an inducer in the lac operon. The regulatory gene becomes active when the bacteria's media contains lactose. The repressor protein will bind to the inducer and become inactive, enabling operon transcription. Therefore, in this instance, the lac operon is negatively regulated.
Escherichia coli, a helpful gut bacterium, need amino acids to survive because, like humans, it needs to make proteins. Tryptophan is one of the amino acids they require. E. coli will use tryptophan to create proteins if it is present in the environment. E. coli, however, can also synthesize tryptophan on their own utilizing enzymes that are encoded by five different genes. The so-called trp operon contains these five genes close to one another.
Hence, operon functioning is determined by presence of inducer.

Within a cell, the amount of protein made using a given mRNA molecule depends partly on...
A. the presence of certain transcription factors.
B. the rate at which the mRNA is degraded.
C. the degree of DNA methylation.
D. the number of introns present in the mRNA.
The amount of protein produced in a cell utilizing a particular mRNA molecule is somewhat influenced by the rate of mRNA degradation. Here option B is the correct answer.
DNA is converted into mRNA, which joins cytoplasmic ribosomes to act as a template for protein production. There are many levels at which gene expression is regulated.
One such regulatory system is the longevity of mRNA and the pace of its degradation which in turn influences the availability of templates again for the process of protein synthesis and so keeps a check on the overall quantity of protein being generated in a cell.
For instance, bacterial mRNA has a relatively short life cycle, which enables them to swiftly adjust the pattern of protein production in response to environmental changes.

To make a buffer you will need to mix a solution of a weak base with a weak acid. We will be making a phosphate buffer by combining a phosphate base K2HPO4 (dibasic monohydrogen phosphate) with a phosphate acid KH2PO4 (monobasic dihydrogen phosphate). Equal amounts of each should provide a solution with a pH of 6.8.
Determine the mass of 1 mole of each of the phosphate salts
1 mole of K2HPO4
1 mole of KH2PO4
To make a 0.1 M solution of K2HPO4 how much salt should you add in a 100 ml solution?
To make a 0.1 M solution of KH2PO4 how much salt should you add in a 100 ml solution?
By the principle of Henderson-Hasselbalch equation:
Mass of 1 mole of each of the phosphate salts 1 mole of K₂HPO₄: 0.575 gm
Mass 0.1 M solution of KH₂PO₄ in a 100 ml solution: 0.912 gm
What is Henderson-Hasselbalch equation?In biological and chemical systems, the Henderson-Hasselbalch equation defines the link between pH as a measure of acidity and the acid dissociation constant (pKa). The equation is particularly useful for calculating the pH of a buffer solution and determining the pH of equilibrium in acid-base processes.
Phosphoric acid pKa's are 2.3, 7.21 and 12.35.
Our required pH is 6.5, so 7.21 will be used.
Hence, mono-potassium dihydrogen phosphate (KH₂PO₄) and dipotassium mono-hydrogen phosphate (K₂HPO₄) will be used.
Handerson-Hasselbach equation:
pH = pKa + log ([A⁻]/[HA])
Therefore, A⁻ is K₂HPO₄ concentration, and for HA is KH₂PO₄ concentration:
or, 6.5 = 7.21 + log(A⁻/HA)
or, log(A⁻/HA)=-0.71
or, A⁻/HA = 0.49
We know that total salt concentration = 0.1 M
HA+A=0.1
A⁻/HA=0.49
So, HA+0.49 HA=0.1
[HA] = 0.1/1.49 = 0.067M
[A] = 0.1-0.067M = 0.033M
Therefore, the concentration of K₂HPO₄ = 0.033M
and the concentration of KH₂PO₄ = 0.067M
Since, we are preparing 100 ml or 0.1 L of the solution,
Thus, the weight of K₂HPO₄ = (0.033M x mol.weight)x 0.1 L
= (0.033M x 174.2 g/mol)x 0.1 L
= 0.575 g of K₂HPO₄ required for 0.1 L
Similarly, we can calculate for KH₂PO₄:
or, wieght of KH₂PO₄ = (0.067M x mol.weight)x 0.1L
= (0.067M x 136.086 g/mol)x 0.1L
= 0.912 g of KH₂PO₄ required for 0.1L buffer solution.
Therefore, we need to take 0.575 g of K₂HPO₄ + 0.912 g of KH₂PO₄ and dissolve them in 100 ml water to prepare 100mL of a 0.1M potassium phosphate buffer of pH 6.5.

In the spinocerebellar pathway, sensory information travels to the cerebellum along Primary and secondary neurons. The cell body of the primary neuron is housed in the dorsal root ganglion of a spinal nerve or, if the sensation is in the head or neck, the ganglia of the trigeminal or cranial nerves. The secondary neuron acts as a relay and is located in either the spinal cord or the brainstem.
The spinocerebellar pathway is the pathway by which sensory information travels from the periphery of the body to the cerebellum. This pathway involves two types of neurons: afferent and efferent.
1. Afferent neurons: These are sensory neurons that carry nerve impulses from the periphery of the body to the central nervous system (CNS). The afferent neurons of the spinocerebellar pathway start in the muscle spindles and joint receptors of the skeletal muscles and joints. These receptors detect changes in the muscle tension and joint position and send signals to the CNS.
2. Efferent neurons: These are motor neurons that carry nerve impulses from the CNS to the periphery of the body. The efferent neurons of the spinocerebellar pathway start in the cerebellum and end at the skeletal muscles and joints. These neurons carry signals from the cerebellum to the skeletal muscles and joints to control movement.

Recombinant DNA technologyRecombinant DNA technology is a part of genetic engineering whereby the DNA molecule from different species are fused together ( I.e. DNA molecule is taken from a donor and inserted into the DNA of the host ).
Intermolecular forces are the forces that bind molecules together. These forces are significant because they aid chemists in determining a substance's physical characteristics, such as its state, melting and boiling points, and so on.
The stronger the intermolecular interactions, the higher the melting and boiling temperatures. During fertilization, egg and sperm combine to form a zygote, a cell with 46 chromosomes (23 pairs). One homologous chromosome originated from each parent for each chromosomal pair.
They have the same genes in the same order, however the DNA letters of those genes differ somewhat.
If a mutation develops in a germ-line cell (one that will give birth to gametes, such as egg or sperm cells), the mutation can be passed on to the progeny of an organism. This means that the mutation will be carried by every cell in the growing embryo.

These snails alter their shell form and slow down their growth when bluegill sunfish, a predator, is around. They become more resistant to crushing and more defended against predators as a result.
What is a good illustration of phenotypic plasticity?The ability of a genotype to exhibit several phenotypes depending on the environment in which it dwells is known as phenotypic plasticity. According to whether they were raised in the presence or absence of a possible predator, genetically identical water flea clones, for instance, can have different morphologies.

X: found between impermeable rockY: contains the water tableWhat is the aquifer?An aquifer is a layer of unconsolidated materials, rock cracks, or water-bearing, porous rock that is underground. A water well can be used to obtain groundwater from aquifers. Aquifers come in a wide range of varieties.
An aquifer is a water-bearing rock that easily transfers water to wells and springs. The aquifers may be dug into and water pumped out of. The porous rock of the aquifer eventually receives water (recharge) from precipitation.
