Trait : meaning of TRAIT in Hindi - Definition and Translation.
That left the scientists with only two options: either DNA replicated semiconservatively, as Watson and Crick had predicted, or it replicated dispersively. To differentiate between the two, Meselson and Stahl had to let the cells divide again and then sample the DNA after a second round of replication.
The regular pairing of bases in the double-helical DNA structure suggested to Watson and Crick a mechanism of DNA synthesis. Their proposal that new strands of DNA are synthesized by copying of parental strands of DNA has proved to be correct. The DNA strand that is copied to form a new strand is called a template. The information in the template is preserved: although the first copy has a complementary sequence, not an identical one, a copy of the copy produces the original (template) sequence again.
