Q/A :
DNA introduction and structure __
Introduction Of DNA
1.Who exactly discovered the DNA structure, and in what year?
James Watson and Francis Crick discovered the double-helix structure of DNA in the year 1953.
This was made possible through the X-ray diffraction data obtained from the research carried
out by Rosalind Franklin.
Reasoning: Watson and Crick used Franklin’s data to propose the structural model, which
explained DNA's function as a carrier of genetic information. This was a milestone in molecular
biology.
2.What does DNA stand for?
DNA stands for Deoxyribonucleic Acid.
Answer: Deoxyribose sugar, phosphate, and nitrogenous bases are its components; that's why it
is called DNA.
3. State the primary function of DNA in all living organisms.
DNA stores and passes the hereditary or genetic information required for the growth,
development, functioning, and reproduction of an organism.
Reasoning: The information stored in the DNA provides the guidelines for protein synthesis and
regulation of cellular activities, thus guaranteeing life
4. What kind of molecule is DNA classified as?
DNA is classified as a nucleic acid.
Justification: DNA is classified in the group of nucleic acids because RNA is the second
compound that also belongs to the nucleic acids and is responsible for the storage and
expression of genetic information.
5. Where is DNA found in both prokaryotic and eukaryotic cells?
