Semester Exam Review

Front

What determines the amino acids that are combined to create proteins like albumin?

Back

The sequence of nucleotides in DNA.

Front

How do environmental factors influence gene activation in a cell?

Back

They can transcribe DNA to mRNA for translation into proteins.

Front

What allows cells in the body to differentiate into various specialized cell types?

Back

Each cell type expresses different genes at different times.

Front

What is active transport in cellular processes?

Back

Active transport is the movement of molecules across a cell membrane from a region of lower concentration to a region of higher concentration, requiring energy.

Front

Which body systems work together to maintain blood calcium homeostasis?

Back

Excretory, endocrine, skeletal, circulatory, and digestive systems.

Front

What is the role of albumin in the bloodstream?

Back

Albumin helps maintain osmotic pressure and transports various substances in the blood.

Front

What is gene expression?

Back

Gene expression is the process by which information from a gene is used to synthesize a functional gene product, usually proteins.

Front

What is the difference between DNA and RNA?

Back

DNA is double-stranded and contains the sugar deoxyribose, while RNA is single-stranded and contains the sugar ribose.

Front

What is the function of mRNA in protein synthesis?

Back

mRNA carries the genetic information from DNA to the ribosome, where proteins are synthesized.

Front

What is homeostasis?

Back

Homeostasis is the process by which living organisms regulate their internal environment to maintain stable, constant conditions.
