RNA & Protein Synthesis

Front

What is RNA?

Back

RNA (Ribonucleic Acid) is a molecule that plays a crucial role in coding, decoding, regulation, and expression of genes.

Front

What are the three main types of RNA?

Back

The three main types of RNA are mRNA (messenger RNA), tRNA (transfer RNA), and rRNA (ribosomal RNA).

Front

What is the function of mRNA?

Back

mRNA carries the genetic information from DNA to the ribosome, where proteins are synthesized.

Front

What is the role of tRNA in protein synthesis?

Back

tRNA transports amino acids to the ribosome and matches them to the coded mRNA message.

Front

What is the role of rRNA in protein synthesis?

Back

rRNA is a structural component of ribosomes, facilitating the assembly of amino acids into proteins.

Front

What is a codon?

Back

A codon is a sequence of three nucleotides in mRNA that specifies a particular amino acid.

Front

How many bases are in a codon?

Back

A codon consists of three bases.

Front

What is the codon wheel used for?

Back

The codon wheel is used to determine which amino acid is coded for by a specific mRNA codon.

Front

Where does translation occur in the cell?

Back

Translation occurs in the cytoplasm of the cell.

Front

What is the start codon and its significance?

Back

The start codon (AUG) signals the beginning of protein synthesis and codes for the amino acid methionine.
