A gene sequence reads ATCGAT. which represents a substitution mutation.

Biology
1 answer:
KIM [24]3 years ago
4 0

Answer:

D

Explanation:

A substitution is where a base is substituted by another base

A. ATGAT  - this is not a substitution, the C has been <u>deleted</u>

B. UAGCUA  - this is not a substitution, but is the complementary mRNA sequence (you can tell because there are Us instead of Ts)

C. TAGCTA  - this is not a substitution, but is the complementary DNA sequence

D. ATGGAT​ - this is a substitution, the C in the original sequence has been replaced (substituted) by a G.

Evolution can be guided by random processes. What is the effect called when some genotypes are lost in a small population over t
soldi70 [24.7K]

Answer:

Genetic drift

Explanation:

Genetic drift is defined as the random change in allelic frequencies from one generation to the other.

Genetic drift is an evolutionary mechanism in which the allelic frequencies in a population change through many generations. Its effects are harder in a small-sized population, meaning that this effect is inversely proportional to the population size. Genetic drift results in some alleles loss, even those that are beneficial for the population, and the fixation of some other alleles by an increase in their frequencies. The final consequence is to <u>randomly</u> fixate one of the alleles. Low-frequency alleles are the most likely to be lost. Genetic drift results in a loss of genetic variability within a population.  

Genetic drift has important effects on a population when this last one reduces its size dramatically because of a disaster -bottleneck effect- or because of a population split -founder effect-.

Proteus vulgaris has a doubling time of roughly 28 minutes. If an initial population of 500 cells is allowed to grow for 6 hours
romanna [79]

<u>Answer:</u> The final population of Proteus vulgaris after 6 hours is 3.71\times 10^{6}cells

<u>Explanation:</u>

We are given:

Proteus vulgaris divides and doubles every 28 minutes

Total time given = 6 hours = 360 min      (Conversion factor: 1 hr = 60 min)

Number of times Proteus vulgaris doubles in 6 hours = \frac{360min}{28min}=12.857times

Calculating the number of bacteria after 6 hours under ideal conditions:

We are given:

Initial population = 500 cells

Number of times it doubles = 12.857 times

Final Proteus vulgaris population = 500\times 2^{12.857}=3709476.8=3.71\times 10^{6}cells

Hence, the final population of Proteus vulgaris after 6 hours is 3.71\times 10^{6}cells
