Protein Synthesis Review

Front

What is tRNA?

Back

tRNA (transfer RNA) is a type of RNA that helps decode a messenger RNA (mRNA) sequence into a protein. It carries amino acids to the ribosome during protein synthesis.

Front

What occurs during transcription?

Back

During transcription, the DNA sequence of a gene is copied into mRNA (messenger RNA). This process takes place in the nucleus.

Front

What organelle is made up of rRNA?

Back

Ribosome. Ribosomes are the cellular structures where protein synthesis occurs, and they are composed of ribosomal RNA (rRNA) and proteins.

Front

What is the function of mRNA?

Back

mRNA (messenger RNA) carries the genetic information from the DNA in the nucleus to the ribosomes in the cytoplasm, where proteins are synthesized.

Front

Where are codons found?

Back

Codons are found in mRNA. A codon is a sequence of three nucleotides that corresponds to a specific amino acid.

Front

What is a codon?

Back

A codon is a sequence of three nucleotides in mRNA that specifies a particular amino acid or a stop signal during protein synthesis.

Front

What is the role of ribosomes in protein synthesis?

Back

Ribosomes are the sites of protein synthesis where mRNA is translated into a polypeptide chain (protein) by linking amino acids together.

Front

What is the difference between DNA and RNA?

Back

DNA (deoxyribonucleic acid) is double-stranded and contains the sugar deoxyribose, while RNA (ribonucleic acid) is single-stranded and contains the sugar ribose.

Front

What is the process of translation?

Back

Translation is the process by which the sequence of nucleotides in mRNA is decoded to produce a specific sequence of amino acids, forming a protein.

Front

What is an anticodon?

Back

An anticodon is a sequence of three nucleotides in tRNA that is complementary to a codon in mRNA, allowing for the correct amino acid to be added during protein synthesis.
