Understanding Genes and Proteins Flashcard

Front

What is a protein?

Back

A protein is a large, complex molecule made up of amino acids that performs various functions in the body, including structural support, transport, and catalyzing biochemical reactions.

What role do proteins play in the skin?

Back

Proteins like collagen, elastin, and keratin provide structure, elasticity, and strength to the skin.

Front

What is collagen?

Back

Collagen is a protein that helps maintain the structure and firmness of the skin, as well as providing support to bones and connective tissues.

Front

What is elastin?

Back

Elastin is a protein that allows skin and other tissues to resume their shape after stretching or contracting.

Front

What is keratin?

Back

Keratin is a fibrous protein that forms the structural framework of hair, nails, and the outer layer of skin.

Front

What happens to collagen and elastin as people age?

Back

As people age, their skin cells produce less collagen and elastin, leading to a weaker skin structure and more wrinkles.

Front

What is a gene?

Back

A gene is a segment of DNA that contains the instructions for making a specific product, usually a protein.

Front

What is genetics?

Back

Genetics is the study of heredity and the variation of inherited characteristics, focusing on how genes influence traits.

Front

How do proteins determine the function of a cell?

Back

Each type of cell has a unique set of proteins that determine how the cell functions, influencing its role in the body.

Front

What is the relationship between genes and proteins?

Back

Genes provide the instructions for making proteins, which perform essential functions in the body.
