DNA polymerase adds new bases to the

• 5' end of the new strand.

• 3' end of the new strand.

• 5' end of the old strand.

• 3' end of the old strand.

Griffith studied __________________, how DNA is able to travel from one cell to another and change its traits.

• DNA replication

• mutations

• transformation

• conjugation

In Griffith's experiment, he realized

• DNA has a specific amount of A based on the amount of T.

• only DNA with radioactive phosphorus entered bacteria cells.

• a material was passed from harmful bacteria to non-harmful bacteria making it harmful.

• only proteins can be passed from one bacteria to another.

In a DNA nucleotide, you will not find

• a covalent bond.

• a phosphate group.

• uracil.

• adenine.

You are examining an RNA molecule. It has a three base sequence and is connected together at certain regions by hydrogen bonds. What type of RNA is this?

• tRNA

• mRNA

• cRNA

A DNA molecule is made of 35% G. How much T will it contain?

• 15%

• 35%

• 70%

• 20%

Which would you be able to find in the backbone of DNA?

• ribose

• covalent bonds

One strand of DNA reads:

5' C G T T A 3'

What will the complementary strand read?

• 3' G C A A T 5'

• 5' G C A A T 3'

• 3' T A C C G 5'
