Biology 24/25 Benchmark #1

Front

What is the process by which genetic information in DNA is converted to proteins?

Back

DNA is transcribed into mRNA, which carries the genetic code to ribosomes for protein synthesis.

Front

How do inheritable genetic variations in skin pigmentation occur?

Back

Genetic variations in skin pigmentation are inherited from both parental lines and further influenced by UV radiation.

Front

What happens to blood glucose levels when insulin production is deficient?

Back

Blood glucose levels increase due to decreased glucose uptake by cells.

Front

Where is insulin produced in the body?

Back

Insulin is produced in the pancreas.

Front

How does insulin regulate blood glucose levels?

Back

Insulin promotes glucose uptake by cells.

Front

What is the role of mitosis in cellular processes?

Back

Mitosis generates new cells.

Front

What is differentiation in the context of cell biology?

Back

Differentiation assigns specific functions to cells.

Front

What is the relationship between mitosis and differentiation in complex organisms?

Back

Mitosis generates new cells, while differentiation assigns specific functions to those cells.

Front

What is mRNA and its role in protein synthesis?

Back

mRNA (messenger RNA) carries the genetic code from DNA to ribosomes for protein synthesis.

Front

How does UV radiation influence skin pigmentation?

Back

UV radiation can lead to variations in skin pigmentation by affecting the expression of genes related to melanin production.
