DNA Replication and Protein Synthesis

Front

What is DNA replication?

Back

The process by which a cell makes an exact copy of its DNA before cell division.

Front

What is the role of helicase in DNA replication?

Back

Helicase is the enzyme that unwinds and separates the two strands of DNA.

Front

What is transcription?

Back

The process of copying a segment of DNA into RNA.

Front

What is translation?

Back

The process by which ribosomes synthesize proteins using mRNA as a template.

Front

What is the function of mRNA?

Back

mRNA (messenger RNA) carries the genetic information from DNA to the ribosome for protein synthesis.

Front

What are the four bases of DNA?

Back

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

Front

What base does adenine pair with in DNA?

Back

Thymine (T).

Front

What base does cytosine pair with in DNA?

Back

Guanine (G).

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 the role of ribosomes in protein synthesis?

Back

Ribosomes are the cellular machinery that assembles amino acids into proteins based on the sequence of mRNA.
