Protein Synthesis Review

Front

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 are the two main stages of protein synthesis?

Back

Transcription and Translation.

Front

What occurs during transcription?

Back

The process where the DNA sequence of a gene is copied into mRNA.

Front

What is the role of mRNA in protein synthesis?

Back

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

Front

What is translation in the context of protein synthesis?

Back

The process where ribosomes read mRNA sequences to assemble amino acids into a polypeptide chain.

Front

What is a frameshift mutation?

Back

A genetic mutation caused by insertions or deletions of nucleotides that shift the reading frame of the genetic code.

Front

What is the function of tRNA?

Back

tRNA transports specific amino acids to the ribosome during protein synthesis.

Front

What is the role of ribosomes in protein synthesis?

Back

Ribosomes are the cellular machinery that facilitate the translation of mRNA into proteins.

Front

What is the difference between DNA and RNA?

Back

DNA is double-stranded and contains deoxyribose sugar, while RNA is single-stranded and contains ribose sugar.

Front

What is the significance of codons in mRNA?

Back

Codons are sequences of three nucleotides in mRNA that specify particular amino acids during translation.
