Which of the processes are coupled (i.e. LINKED) in prokaryotic organisms but uncoupled (i.e. UNLINKED) in eukaryotic organisms?

PilotLPTM [1.2K]

Answer:

Transcription & translation (Ans. A)

Explanation:

Prokaryotic organisms do not have membrane-bound organelles such as the nucleus, thus the process of transcription & translation occurs in the cytoplasm. Also because of the need for rapid life cycle, the mRNA molecules start to be made, & their ribosomes are ready to start making proteins more rapidly than Eukaryote, thus the process of the couple is quicker.

In eukaryotic organisms, transcription process start (happens) inside the nucleus of the cell and translation process can't start until the mRNA is transported out from the nucleus into the cytoplasm.

Bacteria and other microbes can be used to "clean up" an oil spill by breaking down oil into carbon dioxide and water. Two sampl

aksik [14]

Answer:

For sample A, A=17.7 %, T=17.7 %, G=32.30%, C=32.30%

For sample B, A= 28.9%, T=28.9%, G= 21.10%, C= 21.10%

Explanation:

The composition of nitrogenous bases in DNA is calculated using the suggestions proposed by the results of the experiment performed by Erwin Chargaff.

He found that in a DNA sample the composition of purine to pyrimidine is 1:1. This indicates that the amount of purine equals pyrimidine. This can be presented as purines + pyrimidines= 100. Also, adenine binds thymine and cytosine binds guanine.

In the given question,

For sample A

A= 17.7 %, Therefore, thymine will be = 17.7 %,

A+T= 35.40%

Now, G+C=100- 35.40%

G+C= 64.60%

content of G= 64.60/2= 32.30%

content of C= 32.30%

For sample B

T=28.9%, A will be= 28.9%

A+T= 57.80%

G+C=100-57.80%

G+C= 42.20%

Thus content of G will be= 42.20/2=21.10

content of C= 21.10%

Thus,

For sample A, A=17.7 %, T=17.7 %, G=32.30%, C=32.30%

For sample B, A= 28.9%, T=28.9%, G= 21.10%, C= 21.10%

In class we also talked about the metabolism of HDL particles.

zhuklara [117]

Answer:

Explanation:

The basis for the inverse relationship between number of matured HDL in circulation and and cardiovascular disease is that when new HDL entertainment circulation they mature by picking up extra cholesterol until they become mature and high cholesterol level is a major cause of cardiovascular disease and atherosclerosis. The implication of this is that the more the number of matured HDL in circulation, the lower the cholesterol level in the blood thus the lower the risk of cardiovascular disease and atherosclerosis.

When testing for hiv, a/an test produces more accurate results than the elisa test?

34kurt

When testing for hiv, an Antibody screening test produces more accurate results than the elisa test.

Explanation:

An Antibody screening test is the best test available to diagnose a HIV infected person by spotting a particular protein in the infected blood sample. HIV a sexual borne disease is highly contagious and a life taker. The earlier it is been deducted through the antibody screening test and the treatment can be given to expand your life cycle.

ELISA test is a normal test that is done collecting the blood sample of the patients and when known an ELISA test is done on an individual it defers and shakes the person scary to death as it takes a minute for the test but a long wait to announce the result .
