Question

Why do chromosomes look like thread like structures?

Answer 1

Explanation:

hey mate here is ur answer ☺❤

• In the nucleus of each cell, the DNA molecule is packaged into thread-like structures called chromosomes. Each chromosome is made up of DNA tightly coiled many times around proteins called histones that support its structure.

Answer 2

Chromosomes contain DNA molecules. Chromosomes look like thread like structures because without such packaging, DNA molecules would be too long to fit inside cells.
