Question

The genetic information is stored in
A. DNA
B. RNA
C. Ribosome
D. Endoplasmic reticulum

Answer 1

Hint: Genetic material consists of genes that are responsible for all the bodily processes as they have all the information of the body and its functions and structures in the form of genes that can be transcribed and translated later on. This genetic material is inherited from the mother and father.

Complete answer:
The DNA possesses the gene segments that are the unit of the genetic material and inherited from the parents, and also DNA is semi-conservative in nature. Thus it is the storehouse of the genetic information in a cell. During gamete formation, a part of the parents; gene gets passed on to the gamete, at the time of fertilization, when a zygote is formed, it becomes a combination of both the father’s and mother’s genes.
-RNA is ribonucleic acid. RNA is a genetic material only in a few viruses, unlike DNA that is a common genetic material in almost all organisms. Types of RNA are: mRNA, shRNA, snRNA, tRNA, rRNA, out of which the transcription product formed is mRNA that can undergo translation. RNA can also undergo reverse transcription to form DNA.
-Ribosomes are not the location consisting of the genetic material and are mainly present as polysomes that consist of proteins and rRNA and are one of the main units required in the translation as ribosomes recognize the mRNA and allow the translation to happen.
-Endoplasmic reticulum is an organelle that can be rough endoplasmic that possess ribosomes and allow protein synthesis or smooth endoplasmic reticulum that do not have any ribosomes and allow mainly lipid synthesis. They do not contain any genetic material.
Hence, the correct answer is option (A), that is, genetic material is stored in DNA.

Note: DNA is semi-conservative in nature meaning, one strand of DNA acts as a template strand and the other is synthesized from the complementary template strand and the S phase of the cell cycle is responsible for DNA replication.
