DNA

• determines inherited characteristics of all living things.

• is found in the ribosome.

• makes proteins.

• is made up of RNA.

DNA is made up of nucleotides. Nucleotides are made up of

• a sugar, a phosphate, and a base.

• 4 different bases.

• a carbohydrates and a base.

• a sugar and a base.

This rule is otherwise known as the Base Pair Rule.

• Chargaff's Rule

• Charles' Rule

• Watson and Crick's Rule

• Franklin's Rule

In DNA, the bases pair up in the following way:

• A - C and T - G

• A - T and C - G

• A - U and C - G

• A - G and C - T

Rosalin Franklin built the first double helix model of DNA.

• True

• False

DNA Replication occurs

• outside the nucleus.

• before cell division.

• during Mitosis.

• in the ribosome.

During replication, the DNA unzips exposing the bases, then

• opposite bases attach to the exposed bases.

• complimentary nucleotides attach to the explodes bases.

• mRNA attaches to the exposed bases.

• tRNA attaches to the exposed bases.

The three main types of DNA mutations are substitution, deletion, and

• replication.

• insertion.

• duplication.

• mutagens.

A mutagen is

• a physical or chemical agent that harms DNA.

• a member of the X-Men.

• a helpful mutation.

• a harmful mutation.
