Transcription vs. Translation

Front

What is transcription?

Back

Transcription is the process by which the information in a strand of DNA is copied into a new molecule of messenger RNA (mRNA). It occurs in the nucleus of the cell.

Front

What type of RNA is produced during transcription?

Back

mRNA (messenger RNA) is produced during transcription.

Front

Where does transcription occur in the cell?

Back

Transcription occurs in the nucleus.

Front

What is translation?

Back

Translation is the process by which the sequence of nucleotides in mRNA is used to assemble a sequence of amino acids to form a protein.

Front

What type of RNA is involved in translation?

Back

tRNA (transfer RNA) is involved in translation, bringing amino acids to the ribosome.

Front

What is the role of ribosomes in translation?

Back

Ribosomes are the cellular structures where translation occurs, facilitating the assembly of amino acids into proteins.

Front

What determines the sequence of amino acids in a protein?

Back

The sequence of amino acids in a protein is determined by the sequence of nitrogenous bases (A, T, G, C) in the DNA.

Front

What are the three types of RNA involved in protein synthesis?

Back

The three types of RNA involved in protein synthesis are mRNA (messenger RNA), tRNA (transfer RNA), and rRNA (ribosomal RNA).

Front

What is the function of tRNA?

Back

tRNA (transfer RNA) carries amino acids to the ribosome and matches them to the coded mRNA message during translation.

Front

What is the function of rRNA?

Back

rRNA (ribosomal RNA) is a component of ribosomes and plays a crucial role in the synthesis of proteins.
