DNA replication

  1. DNA helicase unwind the double strand DNAat replication fork
  2. The hydrogen bond between base pair are broken to form two template DNA strands
  3. The single strand protein bind to the unpaired DNA to stabilise it
  4. RNA permase synthesis RNA primer and bind to template DNA
  5. The DNA polymerase join the free nucleotides from the nucleoplasm to the DNA strand
  6. Starting from the RNA primer toward the replication fork in 3' to 5' direction of the old template DNA
  7. Another DNA polymerase replace the RNA primer with free nucleotides
  8. A new complementary strand is formed , called leadding strand
  9. Along another strand of template DNA, DNA polymerase formed okazaki fragment
  10. A different DNA polymerase replace the RNA primer with free nucleotides
  11. The DNA ligase join the okazaki fragment to form lagging strand
  12. Two strand of new DNA are simultaneously
  13. Each new DNA molecule is consits of one parental and one new complementary strand 


  • Remember this all,you will get full mark in this question..

感谢

很感谢你们,感谢你们出现在我的生命中
你们让我学会了很多东西,让我受惠很多
如果没有你们,现在的我会怎样呢
真心的感谢你们这六位。。。

他就是我前几天所说的“眼睛”
超美丽的眼睛,超羡慕的,好想要噢

诡异

不安的一天 ,拥有着诡异的天气,心情,和情绪
不管是前者还是后者,都让人很不舒服
阴沉的天气,不安的心情,低落的情绪

不公平,不公平,不公平.....
我要大声地向世界大喊:“不公平”...
这个世界就是那么的不公平
