Explanation:

Histone proteins provide structural support to the chromosomes and help in DNA packaging.

Epigenetics is the study of how particular genes or proteins associated with particular genes are altered chemically in an organism.

When a cell divides and information is passed from one generation to the next, this process is referred to as epigenetic inheritance. For sustaining diverse gene expression patterns in differentiation, development, and disease, epigenetic inheritance is essential.

It is crucial to demonstrate that the inherited phenotype requires passing through the gametes when considering transgenerational epigenetic inheritance (i.e., sperm and eggs). The fact that stressed-out moms generate stressed-out offspring is an instructive illustration.

The step with the highest energy transition state is the slowest step in a reaction that has more than one step. This process is known as the rate-determining step of the reaction because it has the greatest impact on the overall reaction.

What is the slowest step in a reaction mechanism?

The reaction mechanism's slowest step is the rate-determining one. By limiting the overall rate, the rate-determining step establishes the rate law for the overall reaction.

Why is the slowest step used to determine the rate?

This is because it takes longer for the slowest phase to finish since there may be several other processes involved. For instance, before another reaction can take place and a product is immediately produced, a reactant may need to diffuse or migrate to a particular reaction site.

Fermentation breaks down the glucose when no oxygen is available in order to make some ATP, hence option a is correct.

Glycolysis, the first step in fermentation, converts glucose into two pyruvate molecules, two ATP (net), and two NADH.

The constant breakdown of glucose to produce ATP during fermentation is made possible by the recycling of NADH to NAD+, to produce lactic acid and alcoholic fermentation.

Therefore, the fermentation's need for anaerobiosis is made easier by the carbon dioxide that is created in place of the air, hence option a is correct.

2. Cas9 cuts DNA

Every live cell has a genome (DNA). DNA is a double helix structure kept together by the complementary base pairing rule, which states that adenine always pairs with thymine and guanine always pairs with cytosine.

Researchers have discovered thousands of genes that might cause sickness in our bodies. Changing these genes in our bodies is difficult, but it is now achievable thanks to the CRISPR method.

CRISPR:

This method is based on natural system used by bacteria against the DNA of bacteriophages by activating CAS9 protein which due to guide RNA recognizes the target DNA and cut it into pieces.

Mechanism of CRISPR:

Initially, tiny guide RNA forms a complex with the CAS9 endonuclease protein.

This results in the formation of a Cas9/sgRNA complex, which subsequently binds the PAM sequence found inside the target DNA.

Cas9 unzips DNA when it binds to the PAM sequence.

The CAS9 complex contains small guide RNA (sgRNA), which hybridizes with the target DNA.

The blood within the glomerulus produces glomerular hydrostatic pressure, which forces fluid out of the glomerulus and into the glomerular capsule. The fluid in the glomerular capsule generates pressure, which pushes fluid out of the glomerular capsule and back into the glomerulus, thus opposing the glomerular hydrostatic pressure. 

The glomerular filtration rate is the volume of filtrate produced by both kidneys per minute. The hydrostatic pressure and colloid osmotic pressure on either side of the glomerular capillary membrane influence GFR. Remember that filtration occurs when pressure forces fluid and solutes through a semipermeable barrier, with particle size limiting solute movement.

The pressure produced by a fluid against a surface is known as hydrostatic pressure. When a fluid is present on both sides of a barrier, it exerts pressure in opposite directions.The direction of net fluid movement will be in the direction of the lower pressure.

The movement of a solvent (water) across a membrane that is impermeable to a solute in the solution is referred to as osmosis. This produces osmotic pressure, which exists until the solute concentration on both sides of a semipermeable membrane is the same.

Genes that prevent cell division, Cancer results from cells that divide when they should not. A hallmark of cancer is high levels of DNA methylation in cell genomes.

A gene is the primary structural and functional element of heredity. Genes are made out of DNA. Some genes serve as the building blocks for making proteins. However, many genes do not encode proteins. A human gene can be made up of a few hundred DNA nucleotides or more than 2 million bases. According to the Human Genome Project, a global research effort to decipher the human genome's sequence and catalog its genes, humans are believed to have between 20,000 and 25,000 genes.

DNA methylation entails the insertion of methyl groups (-CH3) to sections of DNA where the Cytosine and Guanine bases occur often (often called CpG island). Genes that control the cell cycle, maintain chromosome stability, and control transcription is typically not methylated.

What is mutation?

The nucleotide sequence of an organism's genome, that of a virus, extrachromosomal DNA, or other genetic components can change permanently, a process known as mutation.

Gene structural changes can be divided into two categories: small-scale changes and large-scale changes.

Gene mutations that impact only one or a few nucleotides in a tiny gene are known as small-scale mutations. Examples include:

Point mutations

When a mutation affects one or more nucleotides in the same gene, it is considered to be punctual.

Substitution mutations:

Missense mutations: A nucleotide is changed by another as a result of this point mutation. In some circumstances, this alteration results in a change in the amino acid encoded, which may or may not affect the function of the protein generated by the gene in the case of a gene encoding change or the affinity for a transcription factor in the case of a promoter region of the DNA.

Nonsense mutation: In this case, the changed DNA sequence prematurely instructs the cell to stop producing proteins rather than replacing one amino acid for another. A truncated protein produced by this kind of mutation may operate incorrectly or not at all.

Due to genetic code redundancy (the new triplet codes for the same amino acid as the original triplet), or because it affects a region of the DNA that does not code for a protein, such as an intron, silent mutations do not change the sequence of a protein.
