1.	Question : The total number of genes in humans is far less (lt 25,000) than the previous estimate (upto - 1,40,000 gene). Comment.
Answer» SOLUTION :REPEATED SEQUENCES MAKE up very large portion of the human genome. 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. Less than 2 per cent of the genome codes for proteins.
