What is the difference between Nucleoside and Nucleotide

Nucleotide contains a phosphate, Nucleosides do not.

Polymerization

Process by which nucleotides are added to the 3' end of a DNA strand

5' and 3' ends

You can't replicate from 3' to 5' because it is too difficult to make the bond from the OH to the phosphate

What are the 3 components of Nucleic acid?

Base, Sugar, Phosphate group

Where does the base connect in a nucleic acid?

1'

Where does the phosphate connect in a nucleic acid?

5'

Which part contains the OH group?

Sugar

What is the difference between DNA and RNA?

DNA runs antiparallel with RNA, DNA contains Thymine and RNA contains Uridine. DNA lacks an OH group. DNA is double stranded

How do you tell a purine?

2 rings

How do you tell a Pyramidine?

1 ring

What is Adenine?

Purine. two rings, (Angels and God are pure)(Absent Oxygen)

How can you tell if it's Guanine?

Purine. (angels and God are pure) Has oxygen

How do you know if it's Thymine?

One ring (Pyramidine) -T-wo Oxygens

Cytosine

One ring (Pyramidine) - Has NH2

Uracil

One ring - Two oxygens. CONTAINS NO CH3

How can you find the 5' end in a molecule?

5' generally has a free phosphate group

How can you find a 3' end?

generally has a hydroxyl group

Why are DNA and RNA called acids if they are negatively charged?

They more readily donate protons than accept them.
