Unit 5 DNA History, Structure, and Replication (ADV BIO)

Front

What is gene regulation?

Back

Gene regulation is the process of controlling the expression of genes.

Front

Why is DNA replication important?

Back

DNA replication is important because it ensures genetic information is passed to new cells and each cell has a full copy of DNA.

Front

What are segments of DNA found at specific locations on a chromosome called?

Back

Segments of DNA found at specific locations on a chromosome are called genes.

Front

What does it mean for DNA strands to be antiparallel?

Back

Antiparallel means that the two strands of DNA run in opposite directions.

Front

What is the function of helicase in DNA replication?

Back

The function of helicase in replication is to unzip the DNA double helix.

Front

What is the structure of DNA?

Back

DNA is a double helix composed of two strands of nucleotides.

Front

What are nucleotides?

Back

Nucleotides are the building blocks of DNA, consisting of a sugar, a phosphate group, and a nitrogenous base.

Front

What are the four nitrogenous bases in DNA?

Back

The four nitrogenous bases in DNA are adenine (A), thymine (T), cytosine (C), and guanine (G).

Front

What is the base pairing rule in DNA?

Back

The base pairing rule states that adenine pairs with thymine (A-T) and cytosine pairs with guanine (C-G).

Front

What is the role of DNA polymerase?

Back

DNA polymerase is the enzyme responsible for synthesizing new DNA strands during replication.
