Answer 2

Pentose sugar, phosphate group, base

Question 3

The different purines?

Answer 3

Adenine, guanine

Question 4

The different Pyrimidines?

Answer 4

Cytosine, Thymine, uracil

Question 5

Difference between RNA and DNA?

Answer 5

RNA - pentose sugar is ribose, and the bases are adenine, guanine, cytosine and uracil. One strand
DNA - pentose sugar is deoxyribose and the bases are adenine, guanine, cytosine and thymine. 2 stands

Question 6

how are nucleotides connected?

Answer 6

by covalent bonding between pentose sugar and the phosphate of the next one.

Question 7

What is the structure of DNA

Answer 7

It is a double helix which means antiparallel, run alongside each other but in opposite directions and are held together by hydrogen bonding.
