A biochemist isolated and purified molecules needed for dna replication. Whne she added some dna, replictation occursd but the d
liberstina [14]

Answer:

She left Ligase enzyme out of the mixture.

Explanation:

DNA replication is the process of formation of new molecules of DNA from the existing one. This process occurs in semiconservative way i.e each new strand consist of one newly synthesised strand and one old parent strand that act as template for the formation of new strand. replication on one strand occurs continuously from 5 prime to 3 prime but on other strands it occurs discontinuously from 5 prime to 3 prime because DNA polymerase moves only in one direction from 5 prime to 3 prime. Hence in discontinuous strands gaps remained. These gaps are filled by Ligase enzyme.

Requirements for DNA replication:

DNA replications needs

Primers

DNA Polymerase enzyme

DNA helicase enzyme

Single nucleotide binding protein

dNTPs

and Ligase enzyme.

Correct choice:

She left Ligase enzyme out of the mixture.

What physiological changes can occur during hibernation
Vitek1552 [10]

Answer:

When a species goes into hibernation, the heart rate drops drastically, and the body temperature does as well, in order to conserve energy.  The body becomes induced into a comatose state by releasing chemicals from the brain to body to go into sleep mode.

Explanation:

Hibernation usually occurs during the winter.

Just considering one locus (a specific location on a DNA strand), evidence at a crime scene shows a genotype of 5, 9 STR repeats
marta [7]

Answer:

0.1 x 0.3 = 0.03 = 3%

Explanation:

Assuming a process of random mating in the population, it is possible to infer that the genotype frequencies will be the product of the allele frequencies. The random mating is one of the postulates of the Hardy-Weinberg Law, which is widely used in population genetics to estimate genotypic frequencies when populations are expected to be in an equilibrium state (it is also expected by default in human populations).  In this case, the genotype frequencies will be certainly low (3%), thereby this locus may be useful to investigate a police case.
