Keeping in mind the life cycle of bacteriophages, consider the following problem: During the reproductive cycle of a temperate bacteriophage, the viral DNA inserts into the bacterial chromosome where the resultant prophage behaves much like a Trojan horse. It can remain quiescent, or it can become lytic and initiate a burst of progeny viruses. Several operons maintain the prophage state by interacting with a repressor that keeps the lytic cycle in check. Insults (ultraviolet light, for example) to the bacterial cell lead to a partial breakdown of the repressor, which in turn causes the production of enzymes involved in the lytic cycle. As stated in this simple form, would you consider this system of regulation to be operating under positive or negative control?

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.

The michaelis constant (km) is analogous to _______ that an enzyme has for its substrate. if the km drops then the enzyme has (gained / lost) affinity and if the km increases then the enzyme has (gained / gained) affinity.

Answers

The Michaelis menten constant (Km)

Is analogous to the affinity or the compatibility the particular enzyme has for its given substrate.

If the km drops, then the enzyme has reduced or lost affinity and likewise an increase in the affinity or gain is based on an increase in the value for km.

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.

Answers

Earth's atmosphere contains gases that filter out ultraviolet radiation. So, the correct options for 1, 2, 3, 4, 5, 6, 7, 8, 9 and 10 are D, A, A, D, B, A, B, A, B and C respectively.

What is the atmosphere of the Earth?

The layer of gases that covers the Earth is known as the atmosphere. It is made up of roughly 78% nitrogen, 21% oxygen, and 1% additional gases like argon, carbon dioxide, neon, and methane. It is held in place by the gravity of the Earth. The troposphere, stratosphere, mesosphere, and thermosphere are the four principal layers of the atmosphere.

Gases in the atmosphere of Earth serve as UV radiation filters. CO2 acts as an insulator. The existence of life on Earth is not a result of atmospheric gases. A temperate temperature is kept by the atmosphere. The water cycle and precipitation are made possible by the atmosphere. Life on Earth benefits from gases in the atmosphere because they provide protection from harmful solar radiation.

Earth is protected by ozone in the upper atmosphere. The best way to think about how the atmosphere supports life on Earth is as the source of oxygen in the air. The atmosphere's carbon dioxide and oxygen are necessary for life on Earth.

So, the correct options for 1, 2, 3, 4, 5, 6, 7, 8, 9 and 10 are D, A, A, D, B, A, B, A, B and C respectively.
