a culture of e. coli is irradiated with uv light. the highest frequency of mutations would be obtained if after the irradiation,
Klio2033 [76]

Oftentimes UV light can cause the genetic code of an organism to mutate, leading to a variety of errors, some of which are not compatible with life.

UV light is considered to be a mutagen. What this means is that the exposure of cells to UV light often leads directly to a mutation in the genetic code of that cell. This correlation has been studied extensively and shown to affect the nucleotides of DNA, which are:

  • A base (adenine)
  • T base (thymine)
  • G base (guanine)
  • C base (cytosine)

The exposure to UV light causes the base nucleotides in the DNA of an organism to oxidize. This oxidization causes the base pairs to form dimers. Most often the dimer formed is of a <u>thymine base</u>. This can be thought of as the fusion between two thymine bases, which will alter the frame in which DNA is read and <u>cause all sorts of abnormalities</u>.

kvv77 [185]

Answer:

See explanation

Explanation:

According to the theory of evolution,species which are better adapted to their environment tend to survive and reproduce in a population passing on these favourable characteristics to their offsprings.

During sexual reproduction, genes can be arranged in new ways from chromosomal crossing over and recombination. This introduces new gene combinations(genotype) and ultimately variation in the population.

This variation may also lead to the observation of new phenotypes in the population.

Explanation:

1:they have to have similar structre both internally and general appearance just like us and apes same genus different species

3: migration could vary with the habitat like lack of food in an area could lead them to migrate earlier or later

4:colour variation can also vary because of habitat since some may be darker to camouflage cause of predators like an adaptation.
