Which organelles would create a basic protein that could be modified to move chromatids during metaphase?
bija089 [108]

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.
