Describe two controversies surrounding the race to discover the structure of DNA. What is your opinion about each?Would the same controversies exit today?Why or why not?
DNa replication starts with helicase unwinding DNA. Then polymerase adds a free 3’ end of a growing chain. The leading strand (complementary strand) synthesizes continues on the 5’ to 3’ direction. DNA polymerase adds deoxyribonucleotides to a free 3’ OH. RNA primer sets up for polymerase 3 and then one. Ligase forms a bond between the 3’ OH bond.
A single strand of DNA forms a chromosome. DNA is wrapped in spools of histone.
Crick & Watson: Co-founders of DNA structure.
Franklin: Made important discoveries with DNA and RNA
Not too sure what the controversies are after reading it. I am assuming it has to do with the fact that Franklin was a girl. I do not think the same controversy would occur today.
