23 Protein Synthesis Review

Front

What is the process of transcription?

Back

Transcription is the process of copying a segment of DNA into RNA. It occurs in the nucleus and is the first step in protein synthesis.

Front

What is translation in protein synthesis?

Back

Translation is the process where ribosomes synthesize proteins using the mRNA template. It occurs in the cytoplasm.

Front

What is the role of mRNA?

Back

mRNA (messenger RNA) carries the genetic information from DNA to the ribosome, where proteins are synthesized.

Front

What is the function of tRNA?

Back

tRNA (transfer RNA) delivers amino acids to the ribosome during protein synthesis, matching them to the coded mRNA sequence.

Front

What is the role of ribosomes in protein synthesis?

Back

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

Front

What is the difference between transcription and translation?

Back

Transcription is the process of creating RNA from DNA, while translation is the process of synthesizing proteins from mRNA.

Front

What is the significance of the genetic code?

Back

The genetic code is a set of rules that defines how the sequence of nucleotides in mRNA is translated into amino acids, determining the structure of proteins.

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 the start codon?

Back

The start codon is the first codon of a messenger RNA (mRNA) transcript that is translated by a ribosome, typically AUG, which codes for methionine.

Front

What are stop codons?

Back

Stop codons are codons that signal the termination of protein synthesis. They do not code for any amino acid.
