Answer: The options are not given, here are the options.
A. A zygote is an unfertilized egg
B. A zygote is made up of one cell
c.A zygote is the fusion of two gametes
d.A zygote is where gametes are formed
The correct option is C.
zygote is the fusion of two gametes
Explanation:
A zygote is the fusion of to gamete because it is formed from the union of sperm cell and ovum or egg when the sperm and ovum fuse together after fertilization.
A zygote is start as a single cell but it eventually divides after undergoing fertilization after some days into smaller cells.
Therefore, after two weeks that the zygote divides, it become an embryo.
When the dsDNA copies are then inserted into vectors and cloned into E. coli. the scientist has produced a cDNA library.
A collection of DNA fragments that have been cloned into vectors to identify and isolate desired DNA fragments is known as the DNA library. cDNA libraries and genomic libraries are the two types of libraries.
cDNA (Complementary DNA )library: cDNA is a DNA copy of an mRNA molecule that is produced by reverse transcriptase, a DNA polymerase that can use RNA or DNA as its template.
- These are made by using mRNA as their starting material as templates.
- They only represent genes in the genome that are expressed under particular conditions.
- Because cDNA lacks introns, prokaryotic cells can express it.
