DNA Replication & 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

Where does transcription occur in a eukaryotic cell?

Back

In the nucleus.

Front

What is the role of RNA polymerase in transcription?

Back

RNA polymerase synthesizes RNA from a DNA template.

Front

What are the four nitrogenous bases in DNA?

Back

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

Front

What is the base pairing rule in DNA?

Back

A pairs with T, and C pairs with G.

Front

What is a nucleotide composed of?

Back

A nucleotide consists of a nitrogenous base, a sugar, and a phosphate group.

Front

What is the function of ribosomes in protein synthesis?

Back

Ribosomes are the sites where proteins are synthesized from amino acids.

Front

What is mRNA and its role in protein synthesis?

Back

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

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 process of translation?

Back

Translation is the process where ribosomes synthesize proteins using the information carried by mRNA.
