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.

Answer:
Medulla oblongata
Explanation:
Medulla oblongata is the part of hindbrain and have three vital centers located in it. The vital centers present in medulla are:
1. Cardiac center
2. respiratory center
3. and vasomotor center.
The cardiac center is also known as cardio inhibitory center and is involved in regulation of heart beat. The basic rhythm of breathing is under regulation of respiratory center while diameter of blood vessels is regulated by vasomotor center.
It helps prevent diarihea, which can be a side effect of taking the antibiotic
Both fungi and bacteria are very important for decomposition of organic matter. Decomposition is the break down of dead or decaying organisms. This allows nutrients from all trophic levels to re-enter the soil to be used by primary producers. Fungi are more effective decomposers compared to bacteria as they can <span>use their hyphae to penetrate larger pieces of organic matter, whereas bacteria are restricted to exposed surfaces. </span>
