Question

Chromosomes appearing rod shaped during anaphase are
A. Acrocentric
B. Metacentric
C. Submetacentric
D. Telocentric

Answer 1

Hint:- One can say that the structures which look like thread present inside the nucleus of
animal and plant cells are called chromosomes. It is said that every chromosome is made of the
protein and a single molecule of deoxyribonucleic acid (DNA). It is said that the specific traits are
passed from parents to offspring with the help of chromosomes. However, the DNA is the one that
contains the specific instructions that make each type of living creature unique.

Complete answer:-
A. A chromosome in which the centromere is placed at the terminal end of the chromosome is called
a telocentric chromosome. These types of chromosomes normally are rod-shaped. Or else, we can
also say that their shape is similar to the letter ‘I’.
B. A chromosome in which the centromere is located near to one end of the chromosome is called
an acrocentric chromosome.
C. A chromosome in which the centromere is present in the center so that the two arms are the equivalent is called Metacentric chromosomes. They are normally X-shaped chromosomes.
D. A chromosome in which the centromere is placed near the slightly away from the focus and the
two arms that are a little unequal in length is called a submetacentric chromosome. They are normally in
L-shape.
So, the correct answer is “Telocentric”.

Note:- Thus, we can say that a long DNA molecule with part or all of the genetic material of an
an organism is known as a chromosome. Mostly, the eukaryotic chromosomes include packaging
proteins. From time to time these are also aided by chaperone proteins. They get bind to and
abbreviate the DNA molecule to maintain its integrity.
