DNA and DNA Replication

Front

What are the two molecules that form the sides (backbone) of the DNA ladder?

Back

Deoxyribose sugar and phosphate.

Front

What is the result of DNA replication?

Back

Each DNA molecule consists of one new strand and one original strand.

Front

What is the process in which DNA makes an exact copy of itself?

Back

Replication.

Front

What determines the direction each new strand of DNA is replicated in?

Back

The orientation of the original DNA strands.

Front

What is the complementary strand of DNA for AATCATGGA?

Back

TTAGTACCT.

Front

What are the building blocks of DNA?

Back

Nucleotides, which consist of a deoxyribose sugar, a phosphate group, and a nitrogenous base.

Front

What are the four nitrogenous bases in DNA?

Back

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

Front

What base pairs with Adenine in DNA?

Back

Thymine (T).

Front

What is the role of DNA helicase in DNA replication?

Back

It unwinds and separates the double-stranded DNA.

Front

What is the function of DNA polymerase?

Back

It adds nucleotides to the growing DNA strand during replication.
