AJH DNA and DNA Replication CHECK 1

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 DNA replication?

Back

DNA replication is the process by which a DNA molecule makes an exact copy of itself.

Front

What is the complementary strand of DNA?

Back

The complementary strand of DNA is the strand that pairs with the original strand according to the base pairing rules.

Front

What are the main steps of DNA replication?

Back

1. Unwinding of the DNA double helix. 2. Base pairing of free nucleotides with the template strand. 3. Joining of nucleotides to form a new strand.

Front

What is the role of DNA polymerase in replication?

Back

DNA polymerase is the enzyme that adds nucleotides to the growing DNA strand during replication.

Front

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

Back

The 5' and 3' ends refer to the directionality of the DNA strand, which is important for replication and transcription.

Front

What is a mutation in DNA?

Back

A mutation is a change in the DNA sequence that can lead to changes in the structure and function of proteins.

Front

What is the difference between DNA and RNA?

Back

DNA is double-stranded and contains Thymine (T), while RNA is single-stranded and contains Uracil (U) instead of Thymine.

Front

What is transcription?

Back

Transcription is the process of copying a segment of DNA into RNA.

Front

What is translation?

Back

Translation is the process by which ribosomes synthesize proteins using the information encoded in mRNA.
