New Protein Synthesis no enzymes Review

Front

What is the process of protein synthesis?

Back

Protein synthesis is the process by which cells generate new proteins, involving transcription of DNA to mRNA and translation of mRNA to amino acids.

Front

What is the role of mRNA in protein synthesis?

Back

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

Front

What are amino acids?

Back

Amino acids are organic compounds that serve as the building blocks of proteins. There are 20 different amino acids.

Front

How many nucleotides are needed to code for one amino acid?

Back

Three nucleotides (a codon) are needed to code for one amino acid.

Front

What is the significance of the start codon AUG?

Back

AUG is the start codon that signals the beginning of protein synthesis and codes for the amino acid Methionine.

Front

What is the difference between DNA and RNA?

Back

DNA contains the sugar deoxyribose and the base thymine (T), while RNA contains the sugar ribose and the base uracil (U).

Front

What are the two main stages of protein synthesis?

Back

The two main stages of protein synthesis are transcription (DNA to mRNA) and translation (mRNA to protein).

Front

What is a codon?

Back

A codon is a sequence of three nucleotides in mRNA that specifies a particular amino acid.

Front

What is the function of ribosomes in protein synthesis?

Back

Ribosomes are the cellular structures where protein synthesis occurs, facilitating the translation of mRNA into a polypeptide chain.

Front

What is the role of tRNA in protein synthesis?

Back

tRNA (transfer RNA) transports specific amino acids to the ribosome during translation, matching them to the corresponding codon on the mRNA.
