Honors Bio Protein Synthesis Practice Test

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 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 a point mutation?

Back

A change in a single nucleotide in the DNA sequence, which can lead to changes in the amino acid sequence of a protein.

Front

What is the function of tRNA?

Back

tRNA (transfer RNA) brings amino acids to the ribosome and matches them to the coded mRNA sequence during protein synthesis.

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

Where is DNA located in eukaryotic cells?

Back

In eukaryotic cells, DNA is stored in the nucleus.

Front

What are amino acids?

Back

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

Front

What is the ribosome's role in protein synthesis?

Back

The ribosome is the cellular machinery that assembles amino acids into proteins based on the sequence of mRNA.

Front

What is transcription?

Back

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

Front

What is translation?

Back

Translation is the process of decoding mRNA to synthesize a specific polypeptide chain (protein) at the ribosome.
