Front

What does RNA Polymerase do?

Back

Makes mRNA during transcription.

Front

What is a point mutation?

Back

A change in one nucleotide that can result in an amino acid change, no amino acid change, or an early stop signal.

Front

What are the complementary base pairs from DNA to RNA for the sequence ATG CCC GTC?

Back

UAC GGG CAG.

Front

What type of cells are turned on unless a Co-Repressor binds to the Repressor?

Back

Eukaryotic cells.

Front

What does it mean if a gene is 'turned on' or 'expressed'?

Back

It is making mRNA.

Front

What is transcription?

Back

The process of making mRNA from a DNA template.

Front

What is translation?

Back

The process of synthesizing proteins from mRNA.

Front

What is a frameshift mutation?

Back

A mutation that shifts the reading frame of the genetic message, potentially altering all downstream amino acids.

Front

What is the role of tRNA in protein synthesis?

Back

tRNA transports amino acids to the ribosome during translation.

Front

What is the function of the operator in gene regulation?

Back

The operator is a segment of DNA that a repressor can bind to, blocking transcription.
