DNA Replication

Front

What type of sugar is in DNA?

Back

Deoxyribose is the sugar found in DNA.

Front

What enzyme is responsible for unzipping the DNA strands during replication?

Back

DNA helicase is the enzyme that unzips the DNA strands.

Front

How many copies of DNA are left after replication in both prokaryotes and eukaryotes?

Back

After replication, there are 2 copies of DNA.

Front

What enzyme adds DNA to the ends of chromosomes in rapidly dividing cells?

Back

Telomerase adds DNA to the ends of chromosomes to prevent gene loss.

Front

What is the result of DNA replication in terms of new and original strands?

Back

DNA replication results in two DNA molecules, each with one new strand and one original strand.

Front

What is the role of DNA polymerase in DNA replication?

Back

DNA polymerase synthesizes new DNA strands by adding nucleotides.

Front

What is the structure of DNA?

Back

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

Front

What are the building blocks of DNA?

Back

The building blocks of DNA are nucleotides, which consist 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 base pairs with adenine in DNA?

Back

Thymine (T) pairs with adenine (A) in DNA.
