8. DNA is copied into mRNA during the process of ________________.
MAXImum [283]

question 8

DNA is copied into mRNA  during  the process of  <u>Transcription</u>

  • <u>  </u>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.

Which model of replication did the actual results of the Meselson-Stahl experiment support? Explain your answer.
AfilCa [17]

Answer:

Semi-conservative replication

Explanation:

After the double-helix discovery of Watson and Crick, there were three possible models about the DNI replication:

  • The Conservative model stated that the two strands of DNI together were the template of another new molecule. The final product was the original double-stranded molecule and the new molecule.
  • The semi-conservative model stated that the original DNI molecule separated into two strands, and each of them served as a template for the synthesis of a new complementary strand. The replication product would be two double-stranded DNA molecules, each carrying an original strand a new one.
  • The Dispersive moles stated that the replication product would be two molecules made by a mixture of segments of the original and the new molecules.

Meselson and Stahl joined to discover which of the models was the correct one. To do it they used E. coli and Nitrogen isotopes.

  • First, they extracted DNI from bacteria grown in a medium with N¹⁴ and got its density band by centrifugation.
  • Then they grew bacteria in a medium with N¹⁵, extracted their DNI molecules, centrifugated them, and got the density band, which was heavier than the firsts ones.
  • The researchers then transferred bacteria grown in medium with N¹⁵  to a medium with N¹⁴, and they allowed only one replication process to occur. DNI was extracted and centrifugated again, and a new band appeared. This band was an intermediate form between bands of DNI-N¹⁵ and DNI-N¹⁴.

This event <em>eliminated the conservative model</em>. If this model were correct, the expected result would be to get two bands: one corresponding to the density DNI-N¹⁵ and the other corresponding to the density DNI-N¹⁴.

  • Bacteria grown in a medium with N¹⁵ and then transferred to a medium with N¹⁴ were finally allowed to replicate twice. Their DNI was extracted and centrifugated. The result was two bands: one of them coincided with the intermediate band, and the other one with the DNI-N¹⁴.

<u>This result was conclusive</u> because if the dispersal model were correct, these two bands should not appear, as all the DNI strands would have part of the original molecule.

With this experiment, Meselson and Stahl proved that the correct replication model was the semi-conservative one.
