DNA Replication Practice Flashcard

Front

What is the semi-conservative model of DNA replication?

Back

In the semi-conservative model of DNA replication, each daughter DNA molecule consists of one parent strand and one newly synthesized strand.

Front

What are the correct complementary base pairs in DNA?

Back

The correct complementary base pairs in DNA are Adenine (A) paired with Thymine (T), and Guanine (G) paired with Cytosine (C).

Front

What is the method of DNA replication called?

Back

The method of DNA replication is known as semi-conservative replication.

Front

List the four nitrogenous bases found in DNA.

Back

The four nitrogenous bases found in DNA are Adenine (A), Guanine (G), Cytosine (C), and Thymine (T).

Front

In double-stranded DNA, what is the relationship between Adenine and Thymine?

Back

In a molecule of double-stranded DNA, the amount of Adenine (A) present is always equal to the amount of Thymine (T).

Front

What is the role of nitrogenous bases in DNA?

Back

Nitrogenous bases are essential components of nucleotides, which make up the DNA structure and encode genetic information.

Front

What is the significance of the term 'complementary' in DNA base pairing?

Back

The term 'complementary' refers to the specific pairing of nitrogenous bases in DNA, where A pairs with T and G pairs with C, ensuring accurate replication and transcription.

Front

What is the function 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 during DNA replication.

Front

What is the difference between the leading and lagging strands in DNA replication?

Back

The leading strand is synthesized continuously in the direction of the replication fork, while the lagging strand is synthesized in short segments (Okazaki fragments) away from the replication fork.

Front

What is the role of helicase in DNA replication?

Back

Helicase is an enzyme that unwinds and separates the double-stranded DNA into single strands, allowing replication to occur.
