What term refers to all of the DNA within a cell?

• A. Chromosome
• B. Genome
• C. Genotype
• D. Phenotype

Answer: (B)

The term that refers to all of the DNA within a cell is "genome." The genome encompasses all the genetic material, including genes and non-coding sequences, found within an organism's chromosomes. It essentially represents the complete set of hereditary information in a cell and serves as the blueprint for the organism's development, functioning, and reproduction. In contrast, a chromosome specifically refers to the structure that carries genetic information; it is a single strand of DNA that is coiled and compacted. While chromosomes are part of the genome, they do not encompass the entirety of the genetic material beyond those structures. Genotype refers to the specific genetic makeup of an individual with respect to a trait or a set of traits, which is a subset of the genome. Phenotype, on the other hand, refers to the observable physical and biological characteristics that result from the interaction between the genotype and the environment. Thus, while related to genetics, both genotype and phenotype do not encompass all the DNA within a cell like the term "genome" does.
