Answer:
An accurate description of genes is that genes are made of DNA and code for proteins.
Step-by-step explanation:
Genes are the molecules responsible for containing the genetic information that determines specific characteristics or features of an individual. Genes are housed in chromosomes, in specific locations called locus.
A DNA molecule forms a chromosome, and fragments of that same molecule form the genes on that chromosome. The information contained in each gene codes the synthesis of proteins, as well as the synthesis of RNA.
The other options are not correct because:
1. Proteins are not made of genes, but of amino acids, and they do not code for DNA.
2. Genes are not made of proteins, but of DNA fragments.
3. DNA is not made of carbohydrates.
