Unit 6: Test Review

Front

What process involves the synthesis of mRNA from a DNA template?

Back

Transcription

Front

What type of mutation results in a premature stop codon in the protein sequence?

Back

Nonsense mutation

Front

What is the complementary mRNA sequence to the DNA strand AACTGAA?

Back

UUGACUU

Front

How can different cell types (like muscle and nerve cells) have the same DNA but perform different functions?

Back

The proteins expressed in each cell are different.

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

Define 'mutation' in the context of genetics.

Back

A mutation is a change in the DNA sequence that can lead to changes in protein structure and function.

Front

What is the difference between a silent mutation and a missense mutation?

Back

A silent mutation does not change the amino acid sequence, while a missense mutation results in a different amino acid being incorporated.

Front

What is the function of ribosomes in protein synthesis?

Back

Ribosomes are the sites where translation occurs, synthesizing proteins by linking amino acids together.

Front

What is the significance of the genetic code being universal?

Back

The universal genetic code means that the same codons specify the same amino acids across different organisms.
