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 are the two main stages of protein synthesis?

Back

Transcription and Translation.

Front

What is the role of mRNA in protein synthesis?

Back

mRNA (messenger RNA) carries the genetic information from DNA to the ribosome, where proteins are synthesized.

Front

What is the function of tRNA in protein synthesis?

Back

tRNA (transfer RNA) transports specific amino acids to the ribosome during translation.

Front

What is the role 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 are amino acids?

Back

Amino acids are the building blocks of proteins, and there are 20 different types that combine in various sequences to form proteins.

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 significance of the start codon?

Back

The start codon (AUG) signals the beginning of protein synthesis and codes for the amino acid methionine.

Front

What is the significance of the stop codon?

Back

Stop codons (UAA, UAG, UGA) signal the termination of protein synthesis, indicating that the polypeptide chain is complete.

Front

What is the difference between DNA and RNA?

Back

DNA contains thymine, is double-stranded, and stores genetic information, while RNA contains uracil, is single-stranded, and plays a role in protein synthesis.
