Explanation:
Meiosis produces haploid gametes (ova or sperm) that contain one set of 23 chromosomes. When two gametes (an egg and a sperm) fuse, the resulting zygote is once again diploid, with the mother and father each contributing 23 chromosomes.
Answer: Under normal ambient conditions water is less dense as a solid than as a liquid, so ice floats on water. Most materials are more dense as solids.
Explanation: When water freezes, the molecules do not stack into a close-packed structure. They form a relatively open, honeycomb-like arrangement.
The product of the lac z gene is an enzyme, this enzyme do in the bacterial cell that enzyme is known as β-galactosidase, that's an important a part of the metabolism of lactose.
<h3>What are lactose restriction enzyme ?</h3>
When a restriction enzyme along with BamHI is used to reduce the plasmid, it might reduce the circle at one place. The reduce could open up the circle withinside the LacZ gene. This is due to the fact gene cloners have located a bit of DNA that has many limit enzyme reducing in the LacZ gene.
It cleaves (separates) a disaccharide lactose molecule into a ways greater digestible glucose and galactose lacZ encodes β-galactosidase (LacZ), an intracellular enzyme that cleaves the disaccharide lactose into glucose and galactose.
