Answer:

C

Explanation:

Before the earthquake the gene pool of the parent population was bigger and carried different alleles for a lot of genes.

After the killing of 98% of the population, the surviving one has an incomplete representation of the original gene pool. We can think of this as a gene bottleneck ; the new allele frequencies will be different that the parental population. IE: broadness of stripes has a higher frequency after the earthquake.

You wish to create a mutation in which you prevent access of rna polymerase to the gene. Which region of a gene would you target
Alexus [3.1K]

Answer:

The promoter region/sequence

Explanation:

Promoter sequences/region is where the transcription factors and RNA polymerase must attach before the gene can be transcribed. SO if we mutate this sequence, the transcription factors and RNA polymerase won't recognize it thus would not attach and transcribe the targeted gene.

Vera_Pavlovna [14]

Explanation:

Central dogma represents the pathway in which the information encoded in the DNA flows into proteins.

The DNA is made up of the nucleotide monomers in which the nitrogenous bases are present as one of the constituents. These bases are present in the sequence are transcribed into the RNA molecule through the process of transcription.

The nitrogenous sequences in this RNA molecule are then translated into the proteins through the process of translation during which the sequence is read in pairs of three called "codons". A specific amino acid is attached to the peptide when the codons are read by the translation machinery and a protein is formed.

These proteins could perform various roles in organisms from physical to biochemical and thus the physical traits are controlled by the DNA.
