Explanation:
A protein purification is a series of processes that allow the isolation of a single type of protein from a complex mixture. Protein purification is vital for the characterization of the function, structure interactions of the protein of interest, for example an enzyme a cell receptor or an antibody. The initial material is generally a biological tissue or a microbial culture. There are several steps in the purification process; it can release the protein from the matrix that confines it, separate the protein and non-protein parts of the mixture, and finally separate the desired protein from all the others. This last step may be the most laborious aspect of protein purification.
Techniques used
Homogenization
Cell fractionation
Reversible denaturation with ammonium sulfate

Enzymatic assay
Answer:
Explanation:
S phase. In S phase, the cell synthesizes a complete copy of the DNA in its nucleus. It also duplicates a microtubule-organizing structure called the centrosome. The centrosomes help separate DNA during M phase.

Answer:
during this process the nucleic of the male and female gametes are fused in order to create a zygote .known as fertilisation.Gametes contain half the number of chromosomes of all other cells in the organism .Meaning they are haploid .
Cells responsible for fertilisation:
fertilisation is the fusion of the nucleus of a male gamete with the nucleus of a female gamete ,producing a new cell called a zygote

Answer:
genetic drift
Explanation:
The newly isolated population of beetle would have very different allele frequencies than the main population because of <u>genetic drift.</u>
Genetic drift refers to<u> a change in the frequencies of alleles in a population over generations brought about by pure chance</u>. Genetic drift can cause a bottleneck or founder effect. A <u>bottleneck effect</u> is a temporary decrease in the genetic diversity of a population while the<u> founder effect</u> refers to a decrease in the genetic variability of a new population formed from a small number of individuals that get separated from a larger population.
<em>Hence, the newly formed population of beetles would have lower allele frequencies than the main population due to the founder effect brought about by genetic drift. </em>
