A thread of DNA made up of a string of genes is called a?

Explanation:
A chromosome is a long DNA molecule that carries many genes arranged along its length. This description fits a thread of DNA made up of a string of genes because the genes are lined up along the same DNA molecule and form a single unit of heredity. The genome, by contrast, is the entire set of genetic material in an organism; a nucleotide is one building block of DNA; an allele is a version of a gene. So the term that best matches a single continuous thread of DNA containing multiple genes is chromosome.
