Consider the following two statements about DNA melting temperature:

Biology
1 answer:
Scilla [17]2 years ago
6 0

Given what we know, we can confirm that statement 1 is false, while statement 2 is in fact true. Option D is correct.

<h3>Why is statement 1 false and 2 is true?</h3>

Statement 1 states that the melting point of DNA is determined by the denaturalization of 50% of the double helices in the sample. This is not the case, since the DNA melting point is when 50% of the sample becomes single-standard DNA. Statement 2 is true in that a higher concentration of GC base pairs leads to a higher melting point for DNA.

Therefore, we can confirm that statement 1 is false, while statement 2 is in fact true. Option D is correct.

Describe how the structure of sucrose differs from that of erlose.
grin007 [14]
<span>Sucrose is a disaccharide. It has the chemical formula C12H22O11. Its structure is composed of one glucose and one fructose joined at the glucosyl C1 to the fructosyl C2 by an ether bridge.

Erlose is a trisaccharide, composed of two glucosyls and one fructosyl subunit. Erlose can be formed from sucrose and glucose by joining the glucose C1 to the C4 of the glucosyl subunit of glucose by an ether bridge.</span>

The reaction mixture for PCR is missing the enzyme Taq polymerase. Which step of PCR would this affect?
djyliett [7]

Answer:

The missing of Taq DNA polymerase will affect the DNA synthesis or polymerization step.

Explanation:

Taq DNA polymerase is also known as termostable DNA polymerase because it is able to exert its catalytic activity at high temperature.

     Taq DNA polymerase is used for the 3rd step of polymerase chain reaction which deals with the joining of nucleotides by phosphodiester bond formation.

     The missing or lack of Taq DNA polymerase will affect the DNA synthesis step of PCR.

A species of oak tree grows in deciduous, hardwood forests. This species grows and germinates in close proximity to one another
kifflom [539]

Answer:

clustered distribution (clumped)

Explanation:

In ecology, species distribution refers to the way in which a biological taxon is spatially arranged in a particular geographic area. Species patterns of distribution are fundamental to analyze ecological systems. The main distribution patterns include 1-clustered (clumped) distribution, 2-uniformed distribution, and 3-randomized distribution. The clustered distribution is the most common type of dispersion pattern in nature and occurs when species tend to form small sets of three or more individuals clustered together. A clustered distribution may be due, for example, when resources (e.g., water) are not evenly distributed in the environment (unequal distribution of the resources). Moreover, a uniform distribution occurs organisms keep a uniform, constant, distance from each other (e.g., due to competition for limited resources), while a randomized distribution occurs when individuals are randomly distributed because resources are not limited.
