Front

Which units are repeatedly joined together to form a strand of DNA? Options: amino acids, nucleotides, fatty acids, polysaccharides

Back

nucleotides

Front

What is the enzyme that unwinds the DNA to prepare for replication?

Back

helicase

Front

DNA replication results in two DNA molecules. What is the composition of these molecules?

Back

Each one with one new strand and one original strand.

Front

Order of replication: 3, 4, 2, 1, 3, 1, 4, 2, 2, 1, 4, 3, 3, 4, 1, 2

Back

3, 4, 1, 2

Front

Back

DNA Polymerase

Front

Which series of steps is in the correct order?

1. Recoils

2. Straightens the double helix

3. Breaks hydrogen bonds

4. Adds free nucleotides

Back

Front

Based on the diagram, the enzyme (represented in gray) is most likely...

Options: DNA polymerase, ligase, primase, helicase

Back

DNA polymerase

Front

Why does DNA replicate?

Back

To create another copy for the new cell

Front

What will the first four bases of the new DNA strand look like if copying the template strand? Options: TGGT, ACCA, GTTG, CAAC

Back

TGGT

Front

What is/are the function(s) of DNA polymerase?

Back

connects nucleotides (in the new strand) through covalent bonds, matches the template nucleotides with free nucleotides, proofreads
