RNA and Protein Synthesis

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

How many nitrogen bases make up a codon?

Back

A codon consists of three nitrogen bases.

Front

What process occurs in the ribosome?

Back

Translation is the process that occurs in the ribosome, where mRNA is translated into a protein.

Front

What type of bond holds amino acids together in a protein?

Back

Amino acids are held together by peptide bonds.

Front

What is transcription?

Back

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

Front

What is the function of tRNA in protein synthesis?

Back

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

Front

What is the difference between transcription and translation?

Back

Transcription is the process of creating mRNA from DNA, while translation is the process of synthesizing proteins from mRNA.

Front

What is the significance of the start codon?

Back

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

Front

What are the three main types of RNA involved in protein synthesis?

Back

The three main types of RNA are mRNA (messenger RNA), tRNA (transfer RNA), and rRNA (ribosomal RNA).

Front

What is a mutation?

Back

A mutation is a change in the DNA sequence that can affect protein synthesis.
