RNA and Protein Synthesis

Front

What is mRNA?

Back

mRNA (messenger RNA) is a type of RNA that carries genetic information from DNA to the ribosome, where proteins are synthesized.

Front

What is the role of tRNA in protein synthesis?

Back

tRNA (transfer RNA) is responsible for bringing amino acids to the ribosome during protein synthesis, matching them to the corresponding codons on the mRNA.

Front

What is ribosomal RNA (rRNA)?

Back

rRNA is a form of RNA that makes up the ribosome, the cellular structure where protein synthesis occurs.

Front

What is the function of RNA polymerase?

Back

RNA polymerase is the enzyme that synthesizes mRNA from a DNA template during the process of transcription.

Front

Where does mRNA travel after being synthesized?

Back

After being synthesized, mRNA travels from the nucleus to the ribosome in the cytoplasm for protein synthesis.

Front

What is the structure of a ribosome?

Back

A ribosome is composed of rRNA and proteins, and it has two subunits that come together during protein synthesis.

Front

What is transcription?

Back

Transcription is the process of copying a segment of DNA into mRNA, which 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 chain of amino acids, forming a protein.

Front

What are codons?

Back

Codons are sequences of three nucleotides in mRNA that correspond to specific amino acids or stop signals during protein synthesis.

Front

What is an anticodon?

Back

An anticodon is a sequence of three nucleotides in tRNA that is complementary to a codon in mRNA, allowing for the correct amino acid to be added.
