Question

WHAT IS CHROMOSOME?
Thanks in advance

Answer 1

a thread-like structure of nucleic acids and protein found in the nucleus of most living cells, carrying genetic information in the form of genes.

Answer 2

Hey !!

• The term chromosome was coined by Waldeyer (1888).
• Sutton and Boveri (1902) proved that chromosome is the physical basis of heredity, in the chromosomal theory of inheritance.
• Chromatin material (made of DNA), which is found in the interphase nucleus gets condensed at the time of division into small and thick threads called ''chromosome''.
• Chromosome number for a species remains always same. It is diploid (2n) in somatic cell and haploid (n) is gametes. Chromosome has one or more centromeres (center) and arms (chromatids).
• Genome is the haploid entity of an organism's heredity information. It includes both genes and non-coding sequences of DNA/RNA.

GOOD LUCK !!
