Front

What provides the most reliable evidence of common ancestry for species?

Back

Nucleotide sequences provide the most reliable evidence of common ancestry for species.

Front

What do three consecutive nucleotides in DNA code for?

Back

Three consecutive nucleotides in DNA code for one amino acid.

Front

What is the role of messenger RNA in the nucleus?

Back

Messenger RNA carries the code from the nucleus to the ribosomes to make proteins.

Front

What happens if a nucleus lacks pores?

Back

If a nucleus lacks pores, messenger RNA would not be able to leave the nucleus to provide the code to make proteins.

Front

What is the optimal temperature for an enzyme?

Back

An enzyme's optimal temperature is the temperature at which it functions best, such as 25°C for some enzymes.

Front

How does increasing temperature affect enzyme activity?

Back

Increasing temperature from a lower level to the optimal level can increase the rate of enzyme reactions.

Front

What are homologous structures?

Back

Homologous structures are anatomical features in different species that share a common ancestry.

Front

What is the significance of DNA fingerprints?

Back

DNA fingerprints are used to identify individuals based on their unique DNA patterns.

Front

What is the function of the nuclear membrane?

Back

The nuclear membrane surrounds the nucleus and controls the movement of substances in and out of the nucleus.

Front

What is the relationship between DNA and proteins?

Back

DNA contains the instructions for making proteins, which are essential for cellular functions.
