A plasmid vector has a gene for erythromycin resistance (Ery") and a gene for ampicillin resistance (Amp"). The Ery gene is cut
NikAS [45]

Answer:

Amp resistant phenotypes

Explanation:

Insertion of the desired gene sequence within the sequence of an antibiotic resistance gene makes the transformed cells to lose the resistance against that particular antibiotic. To create a recombinant plasmid vector, the sequence of the gene for erythromycin resistance was cut with the restriction enzyme. This would cause a loss of resistance against erythromycin in the transformed cells. Since the ampicillin resistance gene was intact, the transformed gene would exhibit resistance against ampicillin. Therefore, the transformed cells would be ampicillin-resistant and erythromycin sensitive.

Answer:

Changes (mutations) to genes can result in changes to proteins, which can affect the structures and functions of the organism and thereby change traits. sexual reproduction, genetic information can be altered because of mutations. Though rare, mutations may result in changes to the structure and function of proteins.

What is the best choice for a blank when calibrating the spectrophotometer when you will later measure the absorbance of beverag
ELEN [110]

When calibrating a spectrophotometer, measuring absorbance concurrently is the best option for a blank since it is proportional to the concentration.

Beer's law states that A = a b c, wherein there is the diffusion coefficient at a constant, b is the actual route length, & c is the concentration. Direct proportionality exists between b and c and absorbance.

Once the route length is doubled, incident light contacts double as many molecules in the solution. The consequence is a doubling of absorbance, which is equivalent to a doubling of molecule concentration.

There are two ways to detect chemicals using spectrum scanning. One approach involves turning the monochromator continuously with a stepping motor while gradually altering the wavelength connected to the output slit.

It is more practical to use diode array detectors. Up to a few hundred photodiodes may be incorporated into the chip that makes up this device.
