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 organelle is made up of rRNA?

Back

The ribosome is the organelle made up of ribosomal RNA (rRNA) and proteins, and it is the site of protein synthesis.

Front

What occurs during transcription?

Back

During transcription, the DNA sequence is copied into mRNA, which then carries the information needed for protein synthesis.

Front

Where are codons found?

Back

Codons are found on mRNA and consist of three nucleotides that correspond to specific amino acids.

Front

What is an anticodon?

Back

An anticodon is a sequence of three nucleotides on tRNA that pairs with a complementary codon on mRNA during protein synthesis.

Front

What is the role of tRNA in protein synthesis?

Back

tRNA (transfer RNA) transports specific amino acids to the ribosome, where they are added to the growing polypeptide chain.

Front

Define transcription in the context of protein synthesis.

Back

Transcription is the process of synthesizing RNA from a DNA template, resulting in the formation of mRNA.

Front

What is the function of ribosomes in cells?

Back

Ribosomes are the cellular structures where protein synthesis occurs, translating mRNA into polypeptide chains.

Front

What is the relationship between DNA, mRNA, and proteins?

Back

DNA contains the genetic code, mRNA is the messenger that carries this code to ribosomes, and proteins are synthesized based on the information in mRNA.

Front

What are amino acids?

Back

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