What stages of replication do both cycles have in common? Describe the virion action at each of these stages.

Answers

The stages of replication is  Attachment, Penetration and Replication

The following information should be considered:

  • A bacteriophage means the virus that attacks bacterial cells.
  • The lytic and lysogenic cycles comrpise of two methods of viral replication.
  • In the lytic cycle, the virions generated are released from the host cell while on the other hand in the lysogenic cycle, viral nucleic material are existed into host nucleic material and also they are copied to daughter cells at the time when the host cell reproduces.

The common steps in both cycles are given below:

  1. Attachment – in this step, the bacteriophage attaches itself to the host surface cell to insert its DNA into the host cell.
  2. Penetration – the virus inserts its DNA into the host cell via penetrating the cell membrane of the host cell.
  3. Replication – the viral nucleic material is replicated using the host cell's replication mechanism.

Answer:

Attachment, Penetration and Replication

Explanation:

A bacteriophage is a virus that attacks bacterial cells. The lytic and lysogenic cycles are two methods of viral replication. In the lytic cycle, the virions produced are released from the host cell whereas in the lysogenic cycle, viral nucleic material are incorporated into host nucleic material and are copied to daughter cells when the host cell reproduces. The common steps in both cycles are given below:

1  Attachment – in this step, the bacteriophage attaches itself to the surface of the host cell so as to insert its DNA into the host cell.

2. Penetration – the virus inserts its DNA into the host cell by penetrating the cell membrane of the host cell.

3. Replication – the viral nucleic material is replicated using the host cell's replication mechanism.

Answer:

i think conversion of mass

Explanation:

1. What is the equation for the equilibrium constant, Keq, for the following general reaction: aA + bB → cC + dD Define each term in the equation. 2. What is the actual free energy change of the reaction above? Again, define each term in the equation. Express this equation in terms of mass action Q
3. What is the standard free energy change of the reaction above? Again, define each term.

Answers

Answer:

Explanation:

From the reaction ; aA + bB → cC + dD

1) Keq = equilibrium constant = [A]^a [B]^b / [C]^c [D]^d

where [A] = [B] = [C] = [D] are the concentrations of reactants A, B, C and D respectively.

2) What is the actual free energy change of the reaction above? ;

  • ΔG is the differences between the sum of the free energies of the product and the reactant.
  • Mathematically; ΔG = (cΔGC + dΔGD) - ( aΔGA + bΔGB)
  • ΔG, in terms of reaction quotient ; ΔG = ΔG(standard) + RT lnQ

where R = gas constant and T = temperature.

3) What is the standard free energy change of the reaction above;

  • ΔG(Reaction) = Summation ΔGf(products) - summation ΔGf(reactants)
  • where summation ΔGf = standard free energy of formation

A mutation is found in a tRNA-encoding gene. The wild type allele produces a tRNA that recognizes the codon GAA, and is charged with the amino acid Glutamic acid. The mutant tRNA is still charged with Glu, but the anticodon is mutated such that it recognizes the codon UAA. What effect will this have on translation in these cells

Answers

Answer:

It will bring about a stop to the translation process

Explanation:

The mutant tRNA despite still being charged with Glu, since it's anticodon is mutated and then recognizes and reads the codon UAA which is one of the  stop codons (UAA, UAG and UGA) on the mRNA strand causes the translation process of that particular mRNA strand to stop. And the growing polypeptide chain to be released if any from the ribosomes.

Answer:

The anticodon will be unable to recognize the mRNA codon that is GAA, and the translation of this protein/polypeptide will be abruptly stopped. This may result in a truncated protein which is defected and hence, will be degraded by the relevant mechanisms in place. Since, UAA is actually one of the stop codons, the ribosome will not continue onward with the translation and fall off the mRNA.

Hominins first appear by around 6 million years ago, in the Miocene epoch, which ended about 5.3 million years ago. Our evolutionary path takes us through the Pliocene , the Pleistocene , and finally into the Holocene, starting about 12,000 years ago.
