DNA and DNA replication

Front

What is the structure of a DNA molecule?

Back

A DNA molecule is structured as a double helix.

Front

What determines the genetic code in DNA?

Back

The genetic code in DNA is determined by the order (sequence) of the nitrogen bases.

Front

What is the result of DNA replication?

Back

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

Front

What type of bond joins nitrogenous bases in DNA?

Back

Nitrogenous bases in DNA are joined by hydrogen bonds.

Front

What molecules form the backbone of the DNA ladder?

Back

The backbone of the DNA ladder is formed by deoxyribose sugar and phosphate.

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

How do adenine and thymine pair in DNA?

Back

Adenine pairs with thymine through two hydrogen bonds.

Front

How do cytosine and guanine pair in DNA?

Back

Cytosine pairs with guanine through three hydrogen bonds.

Front

What is the role of DNA polymerase in DNA replication?

Back

DNA polymerase is an enzyme that synthesizes new DNA strands by adding nucleotides complementary to the template strand.

Front

What is the significance of the antiparallel structure of DNA?

Back

The antiparallel structure of DNA allows for the proper base pairing and replication of the DNA strands.
