DNA synthesis involves unwinding two strands of parent DNA, copying each strand to synthesize complementary strands, and release

of parent and daughter DNA. Which of the following accurately describes this process. Is this Anabolic or catabolic reaction

Answer:

This is an anabolic process.

Explanation:

DNA replication involves unwinding two strands of parent DNA, copying each strand to synthesize complementary strands, and releasing the parent and daughter DNA. Thus, it is an anabolic process.

Dafna11 [192]

Creationists criticize the idea of natural selection as a circular argument, or tautology, claiming "the fittest are those that survive, and survival is how fitness is defined. "

The definition of natural selection is not tautological because natural selection is measured by contribution to the next generation, not simply survival of an individual organism.

Tautologies or circular arguments are true at all times and therefore are not productive as theories since they cannot be disproved. A tautology is a statement which is true by necessity.

Natural selection is the prevalent theory which explains biological change by predicting the mechanism behind evolution.

Nevertheless, natural selection can be explained non-tautologically. It should be described as the theory which tries to speculate as well as retrodict evolutionary change by environmental forces affecting the organisms.

HELP!! DNA was isolated from water samples taken from six different sites. This gel
VladimirAG [237]

After running DNA in a gel, bands of different sizes and species might appear. <em>Scientists know silver carp are at North Shore site 1 because one of the bands in lane 1 matches a band in the positive control (Option C). </em>

<h2>Gel</h2>

When DNA was isolated and run in a gel, many bands migrated to different points.

These bands were the different-sized fragments of DNA samples from different species from the six sites.

<em>Researchers wanted to figure out where the silver carp is. </em>

To do it, they needed to identify the bands on the gel that belonged  to the silver carp DNA, so they included negative and positive controls to make comparisons.

<h3>Positive and negative Controls</h3>

Negative and positive controls guarantee the interpretations of the results.

  • The positive control shows the band sizes that belong to the silver carp DNA.

<em>Any</em><em> band</em><em> in the sampling sites that</em><em> matches</em><em> one of the </em><em>positive control</em><em> bands indicates that the species is present at that site.</em>

  • The negative control is the opposite. It is the absence of the species' DNA.

<h3>Results interpretation</h3>

As we can see, there are four sites where the bands match one of the bands of the positive control. These are,

  1. North shore site 1
  2. Chicago site 1
  3. Calumet site 1
  4. Calumet site 2

This means that at these four sites, the silver carp is present.

<em>So scientists know silver carp are at North Shore site 1 because one of the</em><em> bands</em><em> in </em><em>lane 1</em><em> matches a band in the </em><em>positive control</em><em> (Option C). </em>

By looking at the lane of the North Shore site 1, we can also see another band (Thinner and grey). But this band does not match either of the positive control bands. This result suggests that the grey band belongs to another species' DNA.
