what is a gene?
a section of DNA that encodes a specific protenin
a large molecule that preforms a specific function
a point that joins two halves of a chromesome
a structure that contains many chromosomes
The correct answer is: a section of DNA that encodes a specific protein.
A gene is a specific sequence of DNA that contains the instructions for making a particular protein or molecule. Genes determine traits and characteristics in organisms and are the basic units of heredity. They are located on chromosomes, which are structures that contain many genes. However, a gene itself does not join two halves of a chromosome or perform a specific function; it is the sequence of DNA that carries the information for protein synthesis.
