DNA Replication-PRACTICE 2

Front

What is the base pairing rule in DNA?

Back

In DNA, Adenine (A) pairs with Thymine (T) and Guanine (G) pairs with Cytosine (C).

Front

What is the percentage of Adenine if Thymine is 10% in a DNA segment?

Back

If Thymine is 10%, then Adenine is also 10%.

Front

What is the structure of DNA described as a twisted ladder?

Back

The structure of DNA is known as a Double Helix.

Front

Which nitrogen base pairs with Guanine?

Back

Cytosine pairs with Guanine.

Front

What are the four nitrogen bases found in DNA?

Back

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

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 5' and 3' ends of a DNA strand?

Back

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

Front

What is the function of helicase in DNA replication?

Back

Helicase unwinds the double helix of DNA, separating the two strands to allow replication.

Front

What is semi-conservative replication?

Back

Semi-conservative replication is the process by which each new DNA molecule consists of one original strand and one newly synthesized strand.

Front

What is the complementary DNA sequence for the strand CAT TCA CTG?

Back

The complementary sequence is GTA AGT GAC.
