Which term describes the genetic material that contains all of an organism's genes?

• A. Karyotype
• B. Chromosome
• C. Genome
• D. Gene

Answer: (C)

The genome is the entire genetic material that contains all of an organism's genes. It includes not only the genes themselves but also the noncoding regions and regulatory sequences that control how those genes are expressed. A chromosome is one piece of DNA that carries many genes; a karyotype is a chart or image of all chromosomes in a cell; a gene is a single unit of heredity that encodes a specific product. So the term that describes the full set of genetic material containing all genes is the genome.
