Biology EOC Review 3

Front

What carries the instructions for making amino acids in a protein?

Back

The sequence of nitrogen bases on the mRNA.

Front

What is the likely result of habitat destruction due to human expansion?

Back

Many organisms will lose their homes because their habitats have been destroyed.

Front

What cell process is disrupted by the chemical colchicine?

Back

Mitosis.

Front

What effect can a mutation in mRNA have on protein production?

Back

The protein produced will have a different identity.

Front

Why are animals considered heterotrophic?

Back

They are able to obtain nutrients by consuming other organisms or their products.

Front

What is the role of tRNA in protein synthesis?

Back

tRNA carries amino acids to the ribosome, matching them to the codons on the mRNA.

Front

Define photosynthesis.

Back

Photosynthesis is the process by which green plants and some other organisms use sunlight to synthesize foods with the help of chlorophyll.

Front

What is the primary function of DNA?

Back

DNA stores and transmits genetic information.

Front

What is the difference between mitosis and meiosis?

Back

Mitosis results in two identical daughter cells, while meiosis results in four genetically diverse gametes.

Front

What is a mutation?

Back

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