The correct answer is: a section of DNA that encodes a specific protein.
To arrive at this answer, we can analyze each option:
- "A structure that contains many chromosomes": This is incorrect. Genes are not structures that contain many chromosomes. Rather, chromosomes contain genes.
- "A section of DNA that encodes a specific protein": This is the correct answer. Genes are specific sections of DNA that contain the instructions to make a particular protein.
- "A point that joins two halves of a chromosome": This is incorrect. The point that joins two halves of a chromosome is called the centromere.
- "A large molecule that performs a specific function": While this answer is somewhat true, it is not specific enough for the definition of a gene. Genes are specific sections of DNA that code for the production of proteins, rather than performing the function themselves.
Therefore, the correct answer is the second option: a section of DNA that encodes a specific protein.
