Karo-lina-s [1.5K]3 years ago
6 0

Answer:

RNA polymerase

Explanation:

The RNA polymerase is an enzyme used in the transcription of genes in DNA to make mRNA. RNA polymerase binds on the promoter region based on the sequences  that can be identified by the enzyme’s active site. A mutation can distort the interaction between the promoter region and the enzyme’s active site hence throttle up or inhibit transcription.

What can we infer from the stickleback fossil record about evolutionary processes occurring today?
s2008m [1.1K]
<h3><u>Answer;</u></h3>

Evolutionary patterns observed in the fossil record are consistent with evolutionary processes occurring today.

<h3><u>Explanation;</u></h3>
  • Three spine stickleback is a model organisms for studies in evolution because; Stickleback fish are small and have short generation times. These two characteristics make them easy to keep in a lab and useful for conducting genetic studies, since researchers can follow several generations of fish in a relatively short time.
  • Also, stickleback fish populations occur throughout the Northern Hemisphere in a wide range of environments, so researchers can compare different populations and study how they have changed over time in response to different environmental pressures.

Damm [24]

Answer:

The correct option is C. 0.435

Explanation:

To get the results, let's make a punnet square and check the results. The parents in the cross will be heterozygous prefering sorbet. We can say that the alleles for sorbet are dominant over the alleles which prefer ice cream.

          T        t

T        TT       Tt

t         Tt        tt

The results show that there is 25% (0.25) probability that the individual will be homozygous preferring sorbet (TT). 25% (0.25) will have the probability of preferring ice- cream (tt).

50% (0.5) which is nearest to 0.435 will have the probability for having heterozygous alleles (Tt) and preferring sorbet,
