For a science fair project, two students decided to repeat the Hershey and Chase experiment, with modifications. They decided to

label the nitrogenous base of the DNA, rather than the phosphate. They reasoned that each nucleotide has only one phosphate and two to five nitrogenous bases. Thus, labeling the nitrogenous bases would provide a stronger signal than labeling the phosphates. Why won't this experiment work?

4 0

Answer:

Explanation:

The aim of the Hershey and Chase experiment was to show that DNA and not proteins are the genetic material.

Proteins are made up of amino acids which also has a nitrogenous base. Since the whole point of the experiment was to differentiate between the two i.e. show which one is the genetic material, it would be impossible to differentiate between DNA and proteins if the nitrogenous base was labelled.

What is the function of the hydrogen ion concentration gradient?
padilas [110]

Answer:

Notice the large difference in the number of hydrogen ions on the two sides of the membrane. This difference is a hydrogen ion, or proton, concentration gradient. The energy associated with this gradient is used to synthesize ATP from ADP and Pi. This occurs at the ATP synthase complex.

Infer why it is more difficult to make an antiviral drug that fights a virus that replicates through the lysogenic cycle than it
jekas [21]

Answer:

In the lysogenic cycle, the viral genome gets incorporated into the host genome and replicates with the host genome. In the lysogenic cycle, no proteins and enzymes of the virus are formed while in the lytic cycle protein of viral capsid form and new phages generate in the host cell.

So as the viral genome integrates into the host genome in the lysogenic cycle, therefore, it is difficult for any drug to differentially act on the viral genome. So there are great chances for drugs to target the host genome in the host cell.  

But in virus that replicates through lytic cycle drugs can selectively act on viral enzyme and proteins. Therefore it is difficult to make a drug that affects lysogenic virus.

"a type of speciation that involves the development of several species, each adapted to a specific enviornment, is called"
Masteriza [31]

The correct answer is adaptive radiation.

Adaptive radiation is the process by which a single specie or single ancestral lineage, goes through several or various speciation processes and then become adaptively specialized to a specific or particular environmental or ecological place.
