A haploid human genome consists of 3 billion base pairs. If the distance between each base pair is 0.34 nm (a nanometer is one b

illionth of a meter), in a cell that has just completed replication in S phase, what is the length of DNA in this cell, in meters, if all the chromosomes were strung together?

Answer:

The answer is 6.8 meters.

Explanation:

During the S phase of the cell replication, the DNA is doubled before the division of the cell which means that it is twice it's original length.

At 0.34 nanometers, 3 billion base pairs (3.000.000.000) comes up to 3.4 meters and during the S phase the length is doubled so it is 6.8 meters long.

I hope this answer helps.

Answer;

The likely consequence of this ingestion is A decrease in aerobic respiration and an increase in anaerobic respiration.

Explanation;

-Pyruvate dehydrogenase is the enzyme that mediates pyruvate decarboxylation. This step is the critical link between anaerobic and aerobic respiration. With this link broken, cells would be limited to anaerobic respiration. Thus, there will be a decrease in aerobic respiration.

- Lactic acid is a byproduct of anaerobic respiration. With pyruvate decarboxylation blocked, the cell would likely see an increase in such products.

-Also, since, Acetyl-CoA and NADH are products of pyruvate decarboxylation. Blocking this enzyme would lower these concentrations.

antigen processing involves the breakdown of protein antigens and the subsequent association of peptide fragments on the surface
vredina [299]

antigen processing involves the breakdown of protein antigens and the subsequent association of peptide fragments on the surface of antigen-presenting cells with MHC class I or class II proteins.

Antigen is any foreign particle or molecule that can trigger a n immune response in the body.

After the body encounters the antigen cells like macrophages, B cells and dendritic cells will recognise and destroy them. The parts of the antigen will be presented by the macrophages to the T cells and hence they are also called Antigen presenting cells.

Antigen presenting cells will showcase the antigen or its part to the T cells. This is done with the help of a protein called major histocompatiblity complex or MHC complex proteins.

MHC proteins are present on cell surface and holds the antigens to showcase them to T cells.
