Protein Synthesis Review

Front

What is mRNA?

Back

mRNA (messenger RNA) is a type of RNA that carries genetic information from DNA to the ribosome, where proteins are synthesized.

Front

What is the role of DNA in protein synthesis?

Back

DNA contains the genetic blueprint for the synthesis of proteins, which is transcribed into mRNA.

Front

What is transcription?

Back

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

Front

What is translation?

Back

Translation is the process where the sequence of mRNA is read by ribosomes to synthesize proteins.

Front

What are the differences between DNA and RNA?

Back

1. DNA is double-stranded; RNA is single-stranded. 2. DNA has deoxyribose sugar; RNA has ribose sugar. 3. RNA contains uracil instead of thymine. 4. RNA can leave the nucleus; DNA cannot.

Front

What is the Central Dogma of molecular biology?

Back

The Central Dogma describes the flow of genetic information from DNA to RNA to protein.

Front

What is an amino acid?

Back

Amino acids are the building blocks of proteins, linked together by peptide bonds.

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 a stop codon?

Back

A stop codon is a codon that signals the termination of protein synthesis.
