RNA and Protein Synthesis

Front

What are the components of a nucleotide?

Back

A nucleotide includes a pentose sugar, a nitrogenous base, and a phosphate group.

Front

Why are insertion and deletion (frameshift) mutations harmful?

Back

They change all of the codons from the mutation on down the line, which changes the amino acid sequence.

Front

What type of mutation is represented by the change from T-G-A-C-C-A to T-G-A-G-C-A?

Back

Substitution.

Front

Which nitrogen base is not found in RNA?

Back

Thymine.

Front

How is the genetic code read?

Back

The genetic code is read 3 bases at a time in the same direction.

Front

What is the role of mRNA in protein synthesis?

Back

mRNA carries the genetic information from DNA to the ribosome for protein synthesis.

Front

What is the function of tRNA?

Back

tRNA transports amino acids to the ribosome during protein synthesis.

Front

What is transcription?

Back

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

Front

What is translation in the context of protein synthesis?

Back

Translation is the process where ribosomes synthesize proteins using the mRNA sequence.

Front

What are codons?

Back

Codons are sequences of three nucleotides in mRNA that specify a particular amino acid.
