23 Protein Synthesis Review

Front

What is the role of tRNA in protein synthesis?

Back

tRNA (transfer RNA) brings amino acids from the cytoplasm to the ribosomes, where proteins are synthesized.

Front

What does mRNA stand for and what is its function?

Back

mRNA stands for messenger RNA. It carries the genetic information from DNA to the ribosomes for protein synthesis.

Front

What is a ribosome and its role in protein synthesis?

Back

A ribosome is a cellular structure that facilitates the translation of mRNA into a protein by linking amino acids together.

Front

How many nucleotides are in a codon?

Back

A codon consists of three nucleotides.

Front

What is the start codon and its significance?

Back

The start codon is AUG, which signals the beginning of protein synthesis and codes for the amino acid methionine.

Front

What is the end codon and its role?

Back

End codons (UAA, UAG, UGA) signal the termination of protein synthesis.

Front

What is the primary function of DNA?

Back

DNA contains the instructions for building proteins and is the genetic material of living organisms.

Front

What are amino acids and their role in proteins?

Back

Amino acids are the building blocks of proteins, linked together in a specific sequence to form a protein.

Front

What is the process of transcription?

Back

Transcription is the process of copying a segment of DNA into mRNA.

Front

What is translation in the context of protein synthesis?

Back

Translation is the process where ribosomes read mRNA and assemble amino acids into a polypeptide chain.
