what environment stimulates evolution of drug-resistant pathogens?

Answers

Answer 1

The presence of an enzyme called penicillinase results in drug-resistant pathogens.

What causes drug-resistant pathogens?

Misuse and overuse of antimicrobials are the main drivers in the development of drug-resistant pathogens.

What is the function of penicillinase?

A bacterial strain exposed to penicillin may produce an extracellular enzyme called penicillinase which leaves the bacterial cell and degrades the penicillin around it by hydrolyzing the cyclic amide bond in the beta-lactam ring of penicillin and thus inactivates the antibiotic.

Thus, the presence of the enzyme penicillinase results in drug-resistant pathogens.

What part of the cell cycle result in the splitting of the new cells?( it’s not mitosis btw)

Answers

During cytokinesis (division of cytoplasm), the splitting of the new daughter cells takes place. It occurs after karyokinesis, which results into equal division of nuclear material.

What is Cell division?

Cell division is the process of formation of new cells which are also called as daughter cells from the parent cell. It is a part of the cell cycle.

During cell division, two daughter cells are produced from a single parent cell. Cell division is of two types: Mitosis and Meiosis. Mitosis results into formation of daughter cells which are exactly similar to the parent cells. Meiosis is the cell division which occurs in gamete cells and produce cells which contain half of the original genetic material and are different from the parent cell due to recombination of chromosomes.

During cell division, two processes occur which are karyokinesis and cytokinesis. Karyokinesis is the division of nucleus and cytokinesis is the division of cytoplasm which results into formation of daughter cells.

nondisjunction occurs when group of answer choices members of a chromosome pair fail to separate. an entire pair of chromosomes is lost during meiosis i. a portion of a chromosome breaks off and is lost. chromosomes replicate too many times. two chromosomes fuse into one.

Answers

Nondisjunction occurs when members of a chromosome pair fail to separate.

In the field of biology, nondisjunction can be described as a disorder in which the homologous chromosomes do not separate from each other during the cell division process.

As a result of nondisjunction, one of the daughter cells will have both pairs of chromosomes. This means that it will have an extra chromosome. On the other hand, the other daughter cell will not have any of the homologous chromosomes hence decreasing the number of entire chromosomes in the cell.

The process of nondisjunction can lead to severe diseases and syndromes in the newborn child.

Which of the following statements regarding mutation rates is correct?
A. Mutation rates for all genes of an organism are approximately the same.
B. Mutation rates are independent of exposure to external agents such as UV radiation.
C. Average mutation rates vary among taxonomic groups.
D. Mutation rates are independent of gene size

Answers

Average mutation rates vary among taxonomic groups.

The mutation rate is the probability of a mutation occurring during cellular division. The spontaneous mutation rate in bacteria is about one in a billion reproductions. This factor implies that there is at least one mutant in every billion cell population.

The more variable an organism's environment and the lower fitness of the organism in those environments, the more an increased mutation rate would be favored because there is a greater chance per mutation of a beneficial mutation. The rate of population mutation can have a significant impact on average population fitness. For example, as the rate of mutation increases, the average population fitness decreases due to a higher incidence of harmful mutations.

The host cell is LEAST likely to contribute which of the following enzymes or
enzymatic complex3s to the retroviral life cycle?
A. Ribosomes
B. DNA-dependent RNA polymerase
C. RNA-dependent DNA polymerase
D. DNA-dependent DNA polymerase

Answers

Option C. RNA-dependent DNA polymerase is the right answer.

Retroviruses contain RNA as their genetic material rather than DNA. Inside the host cell, they always go through reverse transcription. For this, they need a key enzyme called reverse transcriptase, also known as RNA-dependent DNA polymerase. This enzyme is not present in host cells. For the host cell's DNA replication, which employs DNA as a template strand, enzymes like DNA-dependent DNA polymerase are required. Additionally, transcription requires the other enzyme RNA polymerase, which is dependent on DNA. In order to produce the final expression of genes as proteins, translation is ultimately carried out within the ribosomal protein complex. Therefore, we can draw the conclusion that the host will provide a significant amount of the enzymes required for cellular activities in the host cells. The host will then supply the least amount of enzyme to retroviruses that are not related to their main dogma. The virus itself must therefore contain this enzyme since it uses RNA as a template strand to create DNA at first. Later, this DNA is translated and transcribed in order to create the essential viral proteins.

When you consider each option, assume that no other changes occur.Check all that apply.a) The magnitude of B increases.b) The magnitude of B decreases.c) The loop rotates through 45 degrees about the vertical axis (vertical dotted line) shown in the diagram.d) The loop rotates through 45 degrees about the horizontal axis (horizontal dotted line) shown in the diagram.e) The loop moves to the right while remaining in the plane of the page.f) The loop moves toward you, out of the page, while remaining parallel to itself. HW1.The vertices of a triangle ABC are A(2, 1), B(-2, 3) and C(4, 5). Find the equation of the median through thevertex AAAssume D be the midpoint of BC
