What type of DNA replication is described as semi-conservative?

Back

In semi-conservative replication, each new DNA molecule consists of one original strand and one new strand.

Front

What amino acid is represented by the codon CCA?

Back

Proline

What are the four bases of DNA?

Back

Adenine (A), Thymine (T), Cytosine (C), Guanine (G).

Front

What is the role of DNA polymerase in DNA replication?

Back

DNA polymerase synthesizes new DNA strands by adding nucleotides complementary to the template strand.

Front

What is the difference between DNA and RNA?

Back

DNA is double-stranded and contains thymine, while RNA is single-stranded and contains uracil instead of thymine.

Front

What is transcription in molecular genetics?

Back

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