Describe the effect of amanitin on the maximum elongation rate for the wild-type and modified RNA polymerases. Determine the rat

io of the average maximum elongation rate for the modified RNA polymerase compared to the wild strain RNA polymerase in Figure 1
Biology

Ainat [17]3 years ago

Answer:

Average max. elongation rate = modified RNA pol./ wild type RNA pol = 2/12 = 0.166 nucleotides per sec.

Explanation:

After treating the wild type and experimental RNA with amanitin solution, the amanitin actively binds to the active site of wild type RNA polymerase, inhibiting addition of nucleotides and also it interferes with the motility of RNA pol. along the DNA template, due to which their is a sharp decline in maximum elongation rate of mRNA. In case of experimental RNA polymerase, due to single base substitution the experimental strain is already having very low elongation rate, but binding of amanitin causes constraint on the motility of RNA polymerase through the DNA template, thereby decreasing the elongation rate. Average max. elongation rate = modified RNA pol./ wild type RNA pol = 2/12 = 0.166 nucleotides per sec.

Temperatures are rising world-wide due to greenhouse gases trapping more heat in the atmosphere.

• Droughts are becoming longer and more extreme around the world.

• Tropical storms becoming more severe due to warmer ocean water temperatures.

• As temperatures rise there is less snowpack in mountain ranges and polar areas and the snow melts faster.

• Overall, glaciers are melting at a faster rate.

• Sea ice in the Arctic Ocean around the North Pole is melting faster with the warmer temperatures.

• Permafrost is melting, releasing methane, a powerful greenhouse gas, into the atmosphere.

• Sea levels are rising, threatening coastal communities and estuarine ecosystems.

In what way are the humerus and the femur similar?
dimaraw [331]
The humerus-
A long bone of the upper forelimb. It articulates proximally with the scapula to form the soulder joint and distally with the radius and ulna to form the elbow joint.
<span>Proximally the humerus has a rounded projection known as the head. </span>

Cranially at the lateral aspect of the head is a large prominence- the greater tubercle. The lesser tubercle lies medially. Both tubercles act as a sight for muscle attachment. At the distal end of the humerus is a condyle which articulates with the radius & ulna & forms part of the elbow.

The diaphysis of the humerus is twisted.
<span>In the dog a supra condylar foramen is present- a large hole in the condyle.
</span>
The Femur-This is the thigh bone and is the largest bone in the body, it is a long bone and is similar in structure to the humerus in that it has a head, neck, shaft & lateral & medial condyles. The femoral head articulates with the acetabulum proximally to form the hip joint, lateral to the head is the greater trochanter and on the medialTh side is a lesser trochanter (for muscle attachment). At the distal end of the femur are 2 condyles that articulate with the tibia to form the stifle joint. Between the 2 condyles is the trochlear groove along which the patella can move.

Here is some information. Hope this helps ☺

Which form of natural selection on polygenic traits results in the creation of two distinct phenotypes? A. Directional selection
mojhsa [17]

Answer;

-Disruptive selection

Disruptive selection results in the creation of two distinct phenotypes.

Explanation;

-Disruptive selection is a type of natural selection that selects against the average individual in a population. The make up of this type of population would show phenotypes of both extremes but have very few individuals in the middle.

-The variance of the trait increases and the population is divided into two distinct groups. The disruptive selection will cause organisms with intermediate traits to reproduce less, and will allow those organisms with extreme traits to reproduce more.
