Answer:

The correct answer is option A) "The plasmid would not contain the human gene because the cuts are not compatible".

Explanation:

One of the basis of genetic engineering is to use the proper restriction enzymes to cut fragments of DNA. After cutting DNA with restriction enzymes most of the time the fragments have sticky ends, which are a few nucleotides that are one stranded and complementary to each other. Scientists take advantage of this characteristic and use the same restriction enzyme to cut genes and plasmid and later put it together with DNA ligases. If genes and plasmids are accidentally cut with different restriction enzyme it is very likely that the plasmid would not contain the human gene because the cuts are not compatible, since no sticky ends are generated.

What are the characteristics of red light, which is absorbed by chlorophylls?
Lilit [14]
<span><span>There are choices for this question namely:

A. Its photons have the shortest wavelength in the visual spectrum
B. Its photons have the highest energy in the visual spectrum
C. Its photons have the longest wavelength in the visual spectrum
D. It is not considered a part of the visual spectrum

The correct answer is that </span>its photons have the longest wavelength in the visual spectrum<span>. Chlorophyll, being green in color (around 495 to 590 nm wavelength), reflects this wavelength; not absorbed. Mostly, the chlorophyll absorbs longer wavelengths of light such as red (around 680 nm wavelength) and blue to violet (around 400 to 480 nm wavelnegth). </span></span>

Now that you have come up with an equation that describes the relationship between amounts of different nucleotide bases in DNA,
Colt1911 [192]

Answer:

G=21 %

T= 29 %

A= 29 %

Explanation:

Since C only binds to G, you have the same amount of C and G, so G is 21 %.

100 % minus 42 % ( 21 % C plus 21 % G=) equals 58 %.

So the other 58 % is made of T and A. Since T only binds to A , the half of the extra 58 % is T and the other half is A. Therefore 29 % is T and 29 % is A

Varvara68 [4.7K]

Diabetes insipidus is a disease characterized by excessive thirst and the excretion of large amounts of highly diluted urine, which can not be reduced by a reduction in fluid intake.

Diabetes insipidus is due to a deficiency of antidiuretic hormone or insensitivity of the kidneys to this hormone. This hormone causes water reabsorption via action on the distal segment of the nephron during dehydration.
