10/25 DNA Structure and Replication v2

Front

What is DNA replication?

Back

DNA replication is the process of making an identical copy of DNA.

Front

What are nitrogenous bases in DNA?

Back

Nitrogenous bases are the building blocks of DNA, consisting of adenine (A), thymine (T), cytosine (C), and guanine (G).

Front

What type of bond joins nitrogenous bases in DNA?

Back

Nitrogenous bases are joined by hydrogen bonds.

Front

What is the complementary base for adenine (A) in DNA?

Back

The complementary base for adenine (A) is thymine (T).

Front

What is the complementary base for cytosine (C) in DNA?

Back

The complementary base for cytosine (C) is guanine (G).

Front

What is the structure of DNA?

Back

DNA has a double helix structure, consisting of two strands twisted around each other.

Front

What is the role of DNA polymerase in replication?

Back

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

Front

What is a nucleotide?

Back

A nucleotide is the basic building block of DNA, consisting of a sugar, a phosphate group, and a nitrogenous base.

Front

What is the significance of the 5' and 3' ends of DNA strands?

Back

The 5' and 3' ends indicate the directionality of the DNA strands, which is important for replication and transcription.

Front

What happens during the unwinding of DNA?

Back

During unwinding, the double helix structure of DNA is separated into two single strands, allowing replication to occur.
