DNA Structure and Replication

Front

What is the role of DNA polymerase in DNA replication?

Back

DNA polymerase is the enzyme responsible for adding free nucleotides to the growing DNA strand during replication.

Front

What are the building blocks of DNA?

Back

Nucleotides are the units that are repeatedly joined together to form a strand of DNA.

Front

If a DNA sequence is CATCAT, what are the matching base pairs?

Back

The matching base pairs are GTAGTA.

Front

What shape does a DNA molecule have?

Back

A DNA molecule has a double helix structure.

Front

Which base does Guanine bond with?

Back

Guanine bonds with Cytosine.

Front

What are the components of a nucleotide?

Back

A nucleotide consists of a phosphate group, a sugar (deoxyribose), and a nitrogenous base.

Front

What is the function of DNA helicase?

Back

DNA helicase unwinds the DNA double helix during replication.

Front

What is the difference between DNA and RNA?

Back

DNA contains deoxyribose sugar and thymine, while RNA contains ribose sugar and uracil.

Front

What is the significance of base pairing in DNA?

Back

Base pairing ensures accurate replication and transcription of genetic information.

Front

What is semi-conservative replication?

Back

Semi-conservative replication is the process where each new DNA molecule consists of one original strand and one newly synthesized strand.
