Question

An advantage of using yeasts rather than bacteria as recipient cells for the recombinant DNA of eukaryotes is that yeasts can ______________.
A. Produce restriction enzymes
B. Excise introns from the RNA transcript
C. Remove methyl groups
D. Reproduce more rapidly

Answer 1

Hint:- As yeast is an eukaryote, it has an intron extraction component. Hence, it is very well utilized for delivering and communicating recombinant DNA of eukaryotes. Yeast is nowadays used in bakery products too.

Complete Answer:-
Yeasts are eukaryotic, single-celled microorganisms delegated individuals from the organism realm. The principal yeast began a huge number of years prior, and in any event 1,500 species are as of now recognized. They are assessed to comprise 1% of all depicted parasitic species.

If we go for Recombinant DNA, it is the overall name for taking a bit of one DNA, joining it with another strand of DNA.Recombinant DNA is likewise here and there alluded to as "fabrication." By joining at least two distinct strands of DNA, researchers can make another strand of DNA.The most normal recombinant cycle includes consolidating the DNA of two different creatures.

The yeast has become the most complex eukaryotic model for recombinant DNA innovation. One of the principle reasons is that the transmission hereditary qualities of yeast is very surely known, and the reserve of thousands of freaks influencing many various aggregates is a significant asset when utilizing yeast as an atomic framework rather than in case of bacterias. In yeast, another significant bit of leeway is the accessibility of a roundabout 6.3-kb normal yeast plasmid. This plasmid, which has a perimeter of 2 μm, has gotten known as the "2-micron" plasmid. It shapes the reason for a few modern cloning vectors. This plasmid is communicated to the cell results of meiosis and mitosis. Yeast vectors can be integrative, can independently repeat, or can look like counterfeit chromosomes, permitting qualities to be disengaged, controlled, and reinserted in sub-atomic hereditary examination.

Yeasts have been widely utilized for utilitarian articulation of eukaryotic qualities since they offer a few preferences.These are the most straightforward eukaryotic life forms and like microorganisms are single-celled, hereditarily all around described, simple to develop and control.

Thus the answer is B.” Excise introns from the RNA transcript ”.

Note:- Yeasts are chemoorganotrophs, as they utilize natural mixes as a wellspring of energy and don't expect daylight to develop. Carbon is gotten generally from hexose sugars, for example, glucose and fructose, or disaccharides, for example, sucrose and maltose.Most yeasts fill best in an unbiased or somewhat acidic pH climate.
