DNA Structure and Replication

Joins the nucleotides together and proofreads each strand for replication.

• Helicase

• DNA Primase

• DNA Polymerase

• DNA Ligase

DNA replication is the process of....

• making less DNA

• making more DNA

The complementary strand of this template sequence would be?

3' A T C C G 5'

• 5' G C C T A 3'

• 5' T A G G C 3'

• 3' T A G G C 5'

• 3' A T C C G 5'

DNA is "packaged" in:

• genes

• chromosomes

• chloroplasts

• ribosomes

Adenine (A) pairs with?

• Thymine (T)

• Cytosine (C)

• Guanine (G)

"Unzips" the original DNA strand, breaks the hydrogen bonds for replication.

• Helicase

• Primase

• Polymerase

• Ligase

How many different types of nucleotides are there in DNA?

• 1

• 2

• 3

• 4

In DNA replication the new strand remains and each has a new DNA strand. This model is called....

• Semi-Conservative

• Half Assist

• Secondary

• Ideal Conservation

The original strand is called the ___________ and the new strand is called the ___________ strand.

• template; complementary

• parent; son

• first, final

DNA strands align......

• antiparallel (one 5' to 3'; other 3' to 5')

• parallel (both 5' to 3')
