Question

What are the structures in a cell that group genes together, are composed of chromatin (dna and protein), and become visible under a light microscope during mitosis?

Answer 1

Answer:

chromosome

Explanation:

During most of the cell cycle, interphase, the chromosomes are somewhat less condensed hence they are not visible as individual objects under the light microscope. However during cell division, mitosis, the chromosomes become highly condensed and are then visible as dark distinct bodies within the nuclei of cells when observed under light microscope

Answer 2

Answer:

chromosomes

Explanation:

they are the units of inheritance because they have the genetic material and during cell division [mitosis a way cells divide] they are visible through the light microscope and help the cell divide
