What is protein synthesis?

Back

The process by which cells generate new proteins, involving transcription of DNA to mRNA and translation of mRNA to amino acids.

Front

What is a codon?

Back

A sequence of three nucleotides in mRNA that corresponds to a specific amino acid.

Front

How many codons equal 1 amino acid?

Back

1 codon.

Front

How many nucleotides equal 1 amino acid?

Back

3 nucleotides.

Front

What is the role of ribosomes in protein synthesis?

Back

Ribosomes are the organelles where proteins are synthesized by translating mRNA into amino acid sequences.

Front

What is transcription in the context of protein synthesis?

Back

The process of copying a segment of DNA into mRNA.

Front

What is the significance of the DNA sequence TACGTTACT when transcribed?

Back

It transcribes to AUGCAAUGA, which is the mRNA sequence that will be translated into a protein.

Front

Why must transcription occur in the nucleus?

Back

Because DNA cannot leave the nucleus, and transcription must occur where the DNA is located.

Front

What is translation in protein synthesis?

Back

The process of decoding mRNA into a polypeptide chain (protein) at the ribosome.

Front

What is the function of mRNA?

Back

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