question 8

DNA is copied into mRNA  during  the process of  Transcription

  •  Transcription  is the process by which  information  in the strand of DNA  is copied into   new  molecule  of  messenger  mRNA.
  • The mRNA   formed is a complimentary  to  DNA  strand   whereby replace   of  C with   G,  and  A  with U and T with  A.

 Question 9

Translation  occurs  in  the  ribosome ,  the  organelle  responsible  for  building  proteins.

  •    Ribosome   are responsible for protein synthesis.
  •  They receive  messenger RNA sent  from  the nucleus  and build protein.
  • translation    has  three  steps that is
  1.   initiation -  ribosome assemble  around the target  mRNA.
  2.  elongation- The tRNA transfer  amino acid  to  tRNA  corresponding to  the next codon.
  3. Three  phases of translation initiation  polymerase  bind  to DNA  strand  and move  along until the small ribosomal  subunit  binds to  DNA.
