Question

write a short note on chromosoes

Answer 1

$\underline\bold\pink{\huge{HELLO\:DEAR}}$


⭐ CHROMOSOMES - Chromatin materials are the network of thin, thread like inter-connected structures composed of Deoxyribonucleic acid (DNA). These contain genes. Genes are responsible for passing genetic characters from parents to the offspring. During cell division, this chromatin material condenses to form thick ribbon like structures known as chromosomes. The number of chromosomes varies from organism to organism but is definite in each organism.It also plays a vital role during cell division.



⭐ HAVE A LOOK INTO THE ABOVE MENTIONED PICTURE FOR OBSERVING THE ACTUAL STRUCTURE OF NUCLEUS CONTAINING CHROMATIN MATERIAL.

$<b><i><u>Chromosomes$

✔️ Chromosomes are thread - like structure .

✔️ Chromosomes are found in nucleus.

✔️ The DNA molecule is packaged into thread-like structures in nucleus called chromosomes.

✔️Each chromosome is made up of DNA tightly coiled many times around proteins called histones that support its structure.

✔️ Among organisms with prokaryotic cells , chromosomes consist entirely of DNA.

✔️ Chromosomes carry hereditary information for everything from height to eye color.

✔️ Chromosomes are made of protein and one molecule of DNA, which contains an organism's genetic instructions, passed down from parents.
