Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Rod-shaped structures made up of proteins and DNA are called:
A
Centromeres
B
Chromosomes
C
Histones
D
DNA
Explanation: 

Detailed explanation-1: -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.

Detailed explanation-2: -A telocentric chromosome is a chromosome in which the centromere is located at the terminal end of the chromosome and their shape is similar to the letter i or is rod-shaped. So, the correct answer is ‘Telocentric’.

Detailed explanation-3: -A chromosome is a DNA molecule that contains the genetic information for an organism. The chromosomal structure is composed of the organism’s DNA and special proteins to form the dense, coiled architecture.
