Which of the following statements explains how N-formylmethionine (fMet) is only associated with the 5' AUG initiation codon and

not with internal AUG codons, given that methionine in both cases in encoded by an AUG in the mRNA. Select all that apply. Group of answer choices Only fMet-tRNA(fMet) can bind first to the P site in the ribosome. There are more than one tRNA with the 5' CAU 3' anticodon. fMet is always incorporated at interior AUG sites and then deformylated after translation. The N-formyl group attached to methionine prevents fMet from entering interior positions in a polypeptide.

Answer:

  • Only fMet-tRNA(fMet) can bind first to the P site in the ribosome. ( A )
  • There are more than one tRNA with the 5' CAU 3' anticodon. ( B )
  • The N-formyl group attached to methionine prevents fMet from entering  interior positions in a polypeptide. ( D )

Explanation:

The statements that explains how N--formyl methionine (fMet) is only associated with the 5' AUG initiation codon and not with internal AUG codons, given that methionine in both cases in encoded by an AUG in the mRNA are :

Only fMet-tRNA(fMet) can bind first to the P site in the ribosome. ( A )

There are more than one tRNA with the 5' CAU 3' anticodon. ( B )

The N-formyl group attached to methionine prevents fMet from entering  interior positions in a polypeptide. ( D )

While statement C is wrong.

Why can't both strands of DNA be replicated at the same time?
saw5 [17]

Answer: DNA is a molecule made up of two strands, twisted around each other in a double helix shape. The two strands are complementary which have a 5 prime end and a 3 prime end. To understand this question you must first understand the steps that follow.

DNA Replication:

<u>Step one: </u>

DNA Helicase (unzips) separates the strands.

<u>Step two:</u>

DNA Primase starts the process and makes a small piece of RNA called a primer. This marks the starting point for the DNA.

<u>Step three:</u>

DNA Polymerase binds to the primer and will make the new strand of DNA. DNA Polymerase can only add DNA bases in one direction, from the 5 prime end to the 3 prime end.

  • The leading strand is made continuously.
  • The lagging strand does not run continuously because it runs in the opposite direction. Each fragment is started with an RNA primer. DNA Polymerase then adds a short row of DNA bases from the 5 prime to 3 prime direction. This results in okazaki fragments because it can only replicate in small chunks. The process is repeated.

<u>Step four:</u>

Once the new DNA is complete the enzyme exonuclease removes all the RNA primers from both strands of DNA.

<u>Step five:</u>

Another DNA Polymerase fills in the gaps that are left behind with DNA.

<u>Step six:</u>

DNA Ligase seals up the fragments in DNA, in both strands to make a continuous double strand.

<u>Final answer:</u>

DNA Replication cannot replicate at the same time due to the leading and lagging strand.

Good luck!
