Unit 4: Protein Synthesis

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 is transcription in protein synthesis?

Back

The process of copying a segment of DNA into RNA, specifically mRNA, which carries the genetic information to the ribosome.

Front

What is translation in protein synthesis?

Back

The process where ribosomes read mRNA sequences and assemble amino acids into polypeptide chains to form proteins.

Front

What role do ribosomes play in protein synthesis?

Back

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

Front

What is a codon?

Back

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

Front

What is an anticodon?

Back

A sequence of three nucleotides in tRNA that pairs with a complementary codon in mRNA during translation.

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 DNA and RNA is translated 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 function of mRNA?

Back

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

Front

What is the role of tRNA in protein synthesis?

Back

tRNA (transfer RNA) transports specific amino acids to the ribosome and matches them to the corresponding mRNA codon.
