Phosphate, Deoxyribose sugar, Nitrogenous base.

15

What are the building blocks of DNA?

Nucleotides

10

What is the name given for the structure of DNA?

DNA-double helix

10

Name the four DNA bases:

Adenine, Thymine, Guanine, Cytosine

20

Explain what is base-pairing?

It is how complementary DNA bases bond together. A-T, G-C.

10

What are Chargaffs rules?

In a given DNA sample: %A = %T, %G = %C.

10

What is the back of DNA strand called?

The sugar-phophate backbone.

10

A DNA sample has in total 200 of 1000 bases that are G and C. How may are T?

A&T = 800, T = 400

25

Where is DNA stored in the prokaryotic cell?

Cytoplasm

10

Where is DNA stored in the Eukaryotic cell?

The nucleus

10

What are the bonds that form between two bases?

Hydrogen bonds

10

What does the enzyme, DNA polymerase do?

Builds new strand, checks for errors in DNA code.

15

What does the enzyme, helicase do?

Breaks hydrogen bonds between bases, seperating the two strands.

15

What is the function of ligase?

Molecular "glue" that joins DNA together.

15

What is the function of primase?

This enzyme makes the RNA primer.

15

What is the function of the RNA primer?

The RNA primer marks the beginning of the new DNA strand.
