DNA and DNA Replication

Front

What are the three components of a nucleotide?

Back

sugar, phosphate, nitrogen base

Front

Which units are repeatedly joined together to form a strand of DNA?

Back

nucleotides

Front

What is the monomer of nucleic acids?

Back

Nucleotides

Front

What enzyme unzips the DNA to prepare for replication?

Back

helicase

Front

How many hydrogen bonds do cytosine (C) and guanine (G) have between them?

Back

3

Front

What is the role of DNA polymerase in DNA replication?

Back

DNA polymerase synthesizes new DNA strands by adding nucleotides complementary to the template strand.

Front

What is the structure of DNA?

Back

DNA is a double helix composed of two strands of nucleotides running in opposite directions.

Front

What are the base pairing rules in DNA?

Back

Adenine (A) pairs with Thymine (T) and Cytosine (C) pairs with Guanine (G).

Front

What is the function of the phosphate group in a nucleotide?

Back

The phosphate group links nucleotides together to form the backbone of DNA.

Front

What is the significance of the 5' and 3' ends of a DNA strand?

Back

The 5' end has a phosphate group, and the 3' end has a hydroxyl group, determining the direction of DNA synthesis.
