What is the difference between prophage and viral DNA?
mylen [45]

Answer:

A bacteriophage is a type of virus that attacks bacteria.  In the lytic cycle, the virus hijacks the cell machinery of the bacterium that it has infected. In the lysogenic cycle, the viral DNA is incorporated into the bacterial DNA.

Over time, bacteria have become increasingly resistant to antibiotics. Explains this in terms of natural selection.
zlopas [31]

Answer:

Bacteria with antibiotic resistance gene/s are favored by natural selection.  

Explanation:

The presence of one or more antibiotic resistance genes in the bacteria becomes an adaptive trait in the presence of antibiotics in the surroundings. These bacteria have higher chances of survival and reproduce more to produce more progeny as compared to the bacteria that lack any antibiotic resistance gene. Therefore, the frequency of antibiotic-resistant genes in the population increases over the generations. Here, the increased fitness of bacteria having antibiotic resistance gene/s in the presence of antibiotics represents a natural selection.

A small group of diploid triangular Sticky Notes were fluttering along the coast of The Mainland. A storm blew in and blew the S
muminat

Answer:

Because genetic drift (Founder effect) is acting on this population. Not all the Hardy weinberg criteria are accomplished. There are no random matings and populations are finite-sized.

Explanation:

This is a special case of genetic drift: the founder effect.

The “Founder effect” phenomenon refers to cases where a new population originates from a few founder individuals, coming from a bigger ancestral population, that established in a new environment. This small population might or might not be genetically representative of the original one. This subgroup carries with them some genetic information that they share with their original population. Over time, some genes can be lost, or they can increase in frequency. Some rare alleles might be exceeded or might be completely lost. On Consequence, when the small population grows, it will have a genetically different composition from the original one. In these situations, genetic variability is reduced and enhances the possibility of developing a peculiar allelic composition. In some cases, the founder effect is part of the process of speciation.  

The criteria for maintaining a Hardy-Weinberg equilibrium are:  

  • Random matings
  • No superposed generations
  • No mutations
  • No migration  
  • Infinite population size
  • No natural selection

Genetic drift involved the un-accomplishment of random matings and infinite population sizes.

Genetic drift involves:

  • limited population sizes
  • individuals reproduce by endogamy/exogamy, and matings occur by phenotype.
