Suppose you take glycine tRNA and modify it so that the glycine is changed to valine. You then find that the amino acid sequence

in the generated proteins does not show the expected change. This result would suggest that the protein synthesis machinery recognizes the _______ and is _______ with what was actually found by researchers.

Answer:

Suppose you take glycine tRNA and modify it so that the glycine is changed to valine. You then find that the amino acid sequence in the generated proteins does not show the expected change. This result would suggest that the protein synthesis machinery recognizes the tRNA anticodon and is congruent with what was actually found by researchers.

Explanation:

A group of researchers led by Seymour Benzer demonstrated that the anticodon of the charged tRNA was recognized by the protein synthesis machinery, when they changed the amino acid sequence. This example shows the exact result as found by the researchers.

A DNA fragment is introduced into the lacZ gene of a plasmid, which also contains an ampicillin resistance gene. What is the app
zhenek [66]

Answer: The bacteria transformed with this particular plasmid will form white colonies on the plates containing ampicillin and Xgal.

Explanation: The lacZ gene produces an enzyme called β-galactosidase which is responsible for the breakdown of lactose into glucose and galactose. The lacZ gene is one of the three genes (the other two being lacA and lacY) of the lac operon which is responsible for the transport and mechanism of lactose in E. coli and many other bacteria.

In recombinant DNA technology, when a plasmid is to be used to transform a host cell, such markers are used to help screen the transformed cells from the ones that have not taken up the plasmid. Xgal present in the plates is an artificial substrate which is hydrolyzed by

β-galactosidase into 5-bromo-4-chloro-indoxyl which will dimerize and oxidise into 5,5'-dibromo-4,4'dichloro-indigo. This is a blue pigment which will give blue color to the bacterial cells. Introducing a DNA fragment in this lacZ gene will make it non-functional so it will not be able to produce the enzyme.

Therefore, when a bacterial cell is transformed with a plasmid containing ampicillin resistance gene and a DNA fragment introduced in the lacZ gene and then grown on plates containing ampicillin and Xgal, white colored colonies will appear. The white colonies will show the bacterial cells that have successfully taken up the plasmid with the DNA fragment incorporated in the lacZ gene as this will render the gene non-functional and will not produce β-galactosidase which will breakdown Xgal to give blue colonies. Since the plates contain ampicillin, only the bacterial cells that have been successfully transformed with the plasmid ( the ones that have the DNA fragment and the ones without it) will grow as the ampicillin resistance will give them resistance against ampicillin in the plates. The bacterial cells that have not taken up the plasmid will not be resistant to ampicillin and will not form colonies on the plate.

This is called blue-white screening which is used to identify successfully transformed host cells. A picture of this is given in the attachment, taken from the following website:

makvit [3.9K]

Option A, When cells undergo meiosis, the cells of sexual reproduction are divided into two parts, the first is the meiotic division that is reductional division, and the second is an equational division because they have the same number of chromosomes of the stem cell And in this situation, there is no duplication of DNA.
