Question

The central dogma of molecular genetics states that genetic information flows from:
(A) $DNA\to RNA\to proteins$
(B) $DNA\to RNA\to carbohydrates$
(C) $amino\text{ }acids\to proteins\to DNA$
(D) $DNA\to carbohydrates\to proteins$

Answer 1

Nucleic acids are one of the most important biomolecules present in the human body. These nucleic acids store our genetic information and pass down to future generations. The peculiar structure and shape of nucleic acids can perform their functions.

Complete step by step solution:
Nucleic acids are made up of monomers which are repeating units like biomolecules. The repeating units or monomers in nucleic acids are called nucleotides, which are the building blocks of nucleic acids.
Although proteins are essential components with structure and function, they are not sufficient for their own propagation. The information of specific proteins is stored in nucleic acids. The central dogma of molecular biology states that sequence information can be transferred among nucleic acids.
The flow of the molecular path of genetic information is briefly explained by the central dogma. The flow of genetic information involves four processes with unidirectional.
Replication of DNA copies the genetic information that transcribes into RNA. The RNA sequence translation of amino acid of a polypeptide by translation.
So, the central dogma of molecular genetics states that genetic information flows the path from:
$DNA\to RNA\to proteins$
In the above process, DNA to RNA is that genetic information transcription and RNA to proteins is translation.

The correct answer to this question is option (A).

Note: An unwounded DNA molecule is 6 feet long and if stretched out of all strands in DNA in our body will stretch to 110 billion miles which are linked together. The nucleic acid structures predefine the DNA structure in our body and nucleic acid structure formed from monomers of nucleotides.
