  1. ARepetitive sequences are stretches of DNA sequences that are repeated many times, sometimes hundred to thousan
  2. BRepetitive sequences are thought to have direct coding functions, and they shed light on chromosome structure,
  3. CChromosome 1 has the fewest genes and the Y has the most.
  4. DScientists have identified about 1.4 billion locations where single-base DNA differences (SNPs – single nucleo

Correct answer

A. Repetitive sequences are stretches of DNA sequences that are repeated many times, sometimes hundred to thousan

Step-by-step solution

Some of the salient observations drawn from human genome project are as follows: (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 most genes (2968), and the Y has the fewest (231). (ix) Scientists have identified about 1.4 million locations where single-base DNA differences (SNPs – single nucleoti
