Rod-shaped structures made up of proteins and DNA are called:
|
Centromeres
|
|
Chromosomes
|
|
Histones
|
|
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.
