Why do chromosomes condense at the start mitosis

Biology
1 answer:
Fynjy0 [20]2 years ago
3 0
This condensation is needed to allow the chromosomes to move along the mitotic spindle without becoming tangled or broken during their distribution to daughter cells. DNA in this highly condensed state can no longer be transcribed, so all RNA synthesis stops during mitosis.

Why would a mutation in a somatic cell of a multicellular organism escape detection?
Mashcka [7]

When a somatic cell is mutated, none of the other cells in the organism mutate with it. Screenings usually detect mutations that are in numerous cells and not in just one. That is why a mutation in a somatic cell of a multicellular organism escape detection.

<h3>What are mutations?</h3>

A mutation in biology is an adjustment to the nucleic acid sequence of an organism's, virus's, or extrachromosomal DNA. DNA or RNA can be found in the viral genome. Errors in DNA replication, viral replication, mitosis, meiosis, or other types of DNA damage (such as pyrimidine dimers from exposure to ultraviolet radiation) can result in mutations.

These errors can then lead to error-prone repairs, particularly microhomology-mediated end joining, error-causing repairs, or errors during replication. Due to mobile genetic elements, mutations can also result from the insertion or deletion of DNA segment.

love history [14]

Answer:

peptide antigens by MHC class II molecules

Explanation:

Helper T cells are activated by peptide antigens by MHC class II molecules. These antigens express on the surface of antigen-presenting cells (APCs). After activation, the T helper cells divide and secrete cytokines  to assist the immune response.
