DNA (Structure and function)

Question 1

Nucleotides

Answer 1

Joined monomers that make up DNA.

Question 2

What are Nucleotides made up of.

Answer 2

1 phosphate, 1 five-carbon sugar, 1 nitrogenous base

Question 3

Replication

Answer 3

Copying of DNA to produce two identical DNA molecules, Happens during the ‘S’ phase of the cell cycle before division, Super wound into chromosomes right before cell division

Question 4

DNA Helicase

Answer 4

Unzip the DNA molecule by breaking the hydrogen bonds between the strands.

Question 5

DNA Polymerases

Answer 5

Enzymes that attach to the template strand of DNA at the replication forks and follows the base pairing rules

Question 6

DNA Polymerase

Answer 6

Joins nucleotides to synthesize a new complementary strand of DNA, Also proofreads for each new DNA strand

Question 7

Ligase

Answer 7

Finishes (Double checks) the proofreading

Question 8

Primase

Answer 8

synthesizes RNA primers during DNA replication

Question 9

Steps of replication

Answer 9

1: Seperates the 2 DNA strands, 2: Synthesize a complementary DNA strand, 3: Proofread
