BIO test 2 Chapter 6

The molecule that holds the instructions for all living things

• DNA

• RNA

What do each nucleotide consists of

• sugar, phosphate, and a base

• double helix and DNA

• sugar and phosphate

• phosphate and base

Alternating phosphate and sugar groups make up what of DNA

• backbone

• Sugar

• Phosphate group

• Nucleotide

What does Adenine bond with in DNA

• Thymine

• Guamine

• Cytosine

• Uracil

what does Cytosine bond with

• adenine

• thymine

• guanine

• uracil

Each strand of a DNA in a double helix is

• complementary

• backbone

• bases

• phosphate group

Features of DNA

• two strands of DNA form a double helix

• the bases in opposite strands hydrogen bond according to the AU/GC rule

• the two strands are complementary

• It is only one strand

what makes DNA a great molecule for hereditary information

• the fact that they are complementary

• semi-conservative

• messenger RNA

• robosomes

how is genetic instructions passed down

• DNA replication

• semi-conservative

• compplementary

new DNA molecules are made up of one of the original parental strands plus a new half

• semi conservative

• complementary

• Cell duplication
