7. What is the purpose of the replicases?
masya89 [10]

Answer:

Replicates can be used to measure variation in the experiment so that statistical tests can be applied to evaluate differences. Averaging across replicates increases the precision of gene expression measurements and allows smaller changes to be detected.

Y_Kistochka [10]

Answer:

c. The harmless bacteria had been transformed.  

Explanation:

Fredrick Griffith carried out the first experiment that showed bacteria can get DNA by transformation in 1928.

He used two different strains of the bacteria Streptococcus pneumoniae a)type-III-S or smooth strain-Covered by a protective polysaccharide capsule hence lethal

b) type II-R or rough strain-Lacked the polysaccharide hence non-lethal

In his experiment he observed heat killed Type-III-S strain was not able to kill the mice. However, when its remains was added with rough strain then the blend was able to kill the mice.

When he collected blood  from the dead mice it had live strains of both smooth and rough type.

He came to a conclusion that non-lethal type II-R strain was transformed into lethal type II-S strain by a "transforming principle"  that was supposed to be the part of dead III-S strain bacteria.

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-.
