NucleicAcids:Structure And DNA Replication

Question 1

What is DNA and function?

Answer 1

DNA is DEOXYribonucleic Acid and function is HOLDS GENETIC INFORMATION

Question 2

What is RNA and its function?

Answer 2

RNA is Ribonucleic Acid and function is TRANSFERS GENETIC INFORMATION from DNA to RIBOSOMES

Question 3

Describe the Structure of nucleotide and what are DNA and RNA?

Answer 3

Nucleotide are Phosphate bonded to a Pentose sugar with a nitrogenous Base which forms phosphate backbone in DNA
DNA and RNA are polymers of nucleotide:Polynucleotides
Monomers are nucleotides

Question 4

What Sugar and Bases are present in DNA and RNA and how many Hydrogen bonds present between Base Pairs?

Answer 4

In DNA there is Deoxyribose Sugar and in RNA you have ribose Sugar.
DNA base pairs:Adenine,Thymine,Guanine and Cytosine.
RNA base pairs:Adenine,Uracil,Guanine and Cytosine.
Guanine pairs up with Cytosine-3HydrogenBonds
Adenine pairs up with Thymine/Uracil:2HydrogenBonds

Question 5

What is formed in a Condensation of Nucleotides?

Answer 5

Condensation of nucleotides produce a Dinucleotide
Forms Phosphodiester Bonds

Question 6

What are the difference between DNA and RNA?
[Structures]

Answer 6

DNA:Two polynucleotide chains
Double Helix
RNA:ONE relatively short polynucleotide chain
Single Helix
