Double Bond (Purine=Pyrimidine)

Question 21

Guanine and Cytosine have

Answer 21

Triple Bond

Question 22

Pentose sugar in DNA and RNA

Answer 22

In Pentose Sugar of DNA, on 2nd Carbon, only “H” is present, While in Pentose Sugar of RNA, on 2nd Carbon, OH is present

Question 23

Phosphate sugar is attached to

Answer 23

5th Carbon of Pentose Sugar

Question 24

How phosphate is attached?

Answer 24

From the 3rd Carbon of pentose sugar of DNA, OH is present. O gets removed due to deoxygenated reaction, One space gets empty and Phosphate joins in from there and the chain continues like this

Answer 28

2.2m

Question 29

Theoretically, our body has how much DNA

Answer 29

As much DNA as it can measure light years

Question 30

Nitrogenous base is always attached to which carbon number

Answer 30

CARBON NO 1

Question 31

What is free at 3'

Answer 31

OH

Question 32

Phosphoester bond

Answer 32

Sugar molecule bonds with phosphate grp

Question 33

Phosphodiester bond

Answer 33

A phosphodiester bond is a chemical bond that forms when exactly two hydroxyl groups in phosphoric acid react with a hydroxyl group on other molecules forming ester bonds. It is found in the DNA and RNA backbone.
