Question

function of chromosome

Answer 1

Organisms grow by undergoing cell division to produce new cells and replace older, wornout cells. During this cell division, DNA must remain intact and keep its even distributionthroughout the cells. Chromosomes are important to this process to ensure the DNA is accurately replicated.

Answer 2

The unique structure of chromosomes keeps DNA tightly wrapped around spool-like proteins, called histones. Without such packaging, DNA molecules would be too long to fit inside cells. For an organism to grow and function properly, cells must constantly divide to produce new cells to replace old, worn-out cells.
