What is transcription in protein synthesis?

Back

Transcription is the process of copying a segment of DNA into RNA, specifically mRNA, which serves as a template for protein synthesis.

Front

What is translation in protein synthesis?

Back

Translation is the process where ribosomes convert the sequence of mRNA into a polypeptide chain, forming proteins.

Front

What is the role of RNA polymerase?

Back

RNA polymerase is an enzyme that synthesizes RNA from a DNA template during transcription.

Front

What is the function of ribosomes in protein synthesis?

Back

Ribosomes facilitate the binding of tRNA to mRNA and catalyze the formation of peptide bonds between amino acids.

Front

What is mRNA and its role in protein synthesis?

Back

mRNA (messenger RNA) carries the genetic information from DNA to the ribosome, serving as a template for protein synthesis.

Front

What are codons?

Back

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

Front

What is a stop codon?

Back

A stop codon is a nucleotide triplet in mRNA that signals the termination of translation, indicating that the polypeptide chain is complete.

Front

What is the role of tRNA in translation?

Back

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

Front

What is the difference between the nucleus and cytoplasm in protein synthesis?

Back

Transcription occurs in the nucleus where DNA is located, while translation occurs in the cytoplasm where ribosomes are found.

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 the amino acid sequence of proteins.
