A gene is a section of DNA that encodes a specific protein.
A gene is a section of DNA that encodes a specific protein. To understand this concept and find the answer, you can break down the multiple-choice options and eliminate incorrect answers.
Option 1: "A section of DNA that encodes a specific protein." This option correctly defines a gene as it states that genes are specific sections of DNA responsible for encoding proteins. This is the correct answer.
Option 2: "A point that joins two halves of a chromosome." This option refers to a centromere, which is the point that joins chromatids (not halves) of a chromosome during cell division. This is not the correct answer.
Option 3: "A large molecule that performs a specific function." While this option describes a molecule that performs a specific function, it does not specifically define a gene as a section of DNA responsible for encoding proteins. This is not the correct answer.
Option 4: "A structure that contains many chromosomes." This option refers to a nucleus, which is a structure within a cell that contains multiple chromosomes. However, it does not specifically define a gene. This is not the correct answer.
By considering and eliminating the incorrect options, you can identify that option 1, "A section of DNA that encodes a specific protein," is the correct answer.
