The answer is b. because you wouldn't want a daughter cell that didn't have <em>all </em>necessary to be a complete cell, and this could be messed up if the DNA didn't replicate prior to cell division
The organelles would create a basic protein that could be modified to move chromatids during metaphase is the histine protien which is secreted from the RNA's.
<u>Explanation:</u>
Histone protein is the protein that is associated with the chromosome. The chromatin fibres get condensed into chromosomes on these proteins.
The chromatin fibre i.e. the DNA fibre gets to wrap itself around the histone octamer which is formed of two units of each of Histone H2A H2B H3 and H4. Then the H1 protein seals the turn and thus a chromosome is formed. These histone are produced in the S-phase of the cell cycle. This protein is transcribed into m-RNA's and then translated into protein.
I'm not completely sure, but I'm fairly certain that the answer is B.
Answer:
pathogens
Explanation:
pathogens may occur in various way e.g spread from a person to person by directly body contact
Answer:
D. Spindle Fibers
Explanation:
During anaphase, the centromeres of each chromosome split and the mitotic spindle pulls the sister chromatids apart.
