Options

  1. AChromosome Y
  2. BChromosome 1
  3. CChromosome X
  4. DAll chromosomes have an equal number of genes

Correct answer

B. Chromosome 1

Step-by-step solution

(v) Less than 2 percent of the genome codes for proteins. (vi) Repeated sequences make up a very large portion of the human genome. (vii) Repetitive sequences are stretches of DNA sequences that are repeated many times, sometimes hundred to thousand times. They are thought to have no direct coding functions, but they shed light on chromosome structure, dynamics and evolution. (viii) Chromosome 1 has the most genes (2968) , and the Y has the fewest (231). (ix) Scientists have identified about 1.4 million locations w
