DNA Review

Front

What are genes?

Back

Genes are segments of DNA that contain the instructions for making proteins, which determine the traits of an organism.

Front

What is the role of DNA in living organisms?

Back

DNA serves as the blueprint for the traits of all living things, encoding the information necessary for growth, development, and functioning.

Front

What is the relationship between DNA, genes, and proteins?

Back

DNA contains genes, which are sequences that code for the production of proteins.

What is a protein?

Back

Proteins are large, complex molecules that perform many critical functions in living organisms, including acting as enzymes, hormones, and structural components.

Front

How do variations in DNA affect traits?

Back

Variations in DNA can lead to differences in the proteins produced, which can result in different traits among individuals.

Front

What is the function of a gene?

Back

A gene codes for the production of a specific protein, influencing an organism's traits.

Front

What is the structure of DNA?

Back

DNA is a double helix composed of nucleotides, which include a sugar, a phosphate group, and a nitrogenous base.

Front

What are the four nitrogenous bases in DNA?

Back

Adenine (A), Thymine (T), Cytosine (C), and Guanine (G).

Front

What is the significance of the sequence of bases in DNA?

Back

The sequence of bases in DNA determines the genetic information carried by the DNA and influences the traits of an organism.
