Answer:
Explanation:
The eukaryotic genes of interest can be expressed in the prokaryotic genome or plasmid vector. The following are the steps used for the purpose of expression of eukaryotic genes in the prokaryotic genome.
1. Amplification of the target gene of interest from the eukaryotic genome by PCR or polymerase chain reaction.
2. The selection of the plasmid and digestion of the plasmid DNA with the restriction enzyme.
3. Ligation of the amplified DNA fragment and the plasmid.
4. Introduction of the ligated plasmid into the prokaryotic host organism.

Water purification is the process of removing undesirable chemicals, biological contaminants, suspended solids, and gases from water. The goal is to produce water fit for specific purposes.
Answer:
C As sperm mature, they migrate from the seminiferous tubules into the lumen.
Explanation:
Answer C is false. Different types of germline cells migrate through the seminiferous tubes into the lumen, but not the sperm. Primary spermatocytes located near the basal lamina of the seminiferous tube generate secondary spermatocytes (through meiosis 1) that are located closer to the lumen in relation to the primary spermatocytes; in turn, secondary spermatocytes generate spermatides (through meiosis 2) that are even closer to the lumen. Finally, the spermatides are transformed into sperm through spermatogenesis. Sperms are located very close to the lumen to be released into the lumen through spermiogenesis.
