During DNA replication DVA polymerase lands at origination sites and forms

1 answer:

7 0

DNA polymerase is instrumental in DNA elongation as it catalyzes the addition of deoxyribonucleoside triphosphates to the 3 prime end hydroxyl group of the DNA chain. DNA polymerase binds on the origin of replication, and forms a pre-replication complex with other proteins. The replication complex unwinds DNA during replication

You are an almond grower and want to determine whether almond size (measured as shelled almond weight) is a heritable trait. A s

inn [45]

Answer: 1. S = 0.77

2. R = 0.14

Explanation:

1. Selection differential is the difference between the population mean and the average of the selected parents. Its symbol is S.

S = mean of selected parents - population mean

S = 6.48 - 5.71

S = 0.77

2. Response to Selection is how much gain you make when crossing over selected parents. Its symbol is R.

R = mean of offspring of selected parents - population mean

R = 5.85 - 5.71

R = 0.14

3. Heritability is, basically, a statistical variable that shows how much the variation in a trait is due to genetic factors. Its symbol is h².

To calculate it, use Breeder's Equation:

R = h²S

$h^{2}=\frac{R}{S}$

$h^{2}=\frac{0.14}{0.77}$

h² = 0.18

4. You would expect the production to be strongly influenced by environment, because heritability lies between 0 and 1. Low heritability means there is low level of resemblance between offspring and parents. As this program heritability is low, the resemblance is small, which means the characteristics are influenced mostly by the enviroment.

Several experiments were required to demonstrate how traits are inherited. Which scientist or team of scientists first demonstra

Snowcat [4.5K]

Answer:

Frederick Griffith was the first scientist who discovered that cell contains some components that can be transferred to another cell and cause a permanent change(transformation) in the new cell.

To prove this he performed an experiment in which he took two strains of Streptococcus pneumoniae which contain one rough strain and one smooth strain. Rough strain was non-virulent strain and smooth strain was virulent strain.

So he injected smooth and rough strain in mice and saw that mice die when virulent strain is injected and survive when non-virulent strain is injected. Then he injected heat killed virulent strain in which mice survived.

Then he added remain of heat killed bacteria with live smooth strain of bacteria and infected the mice and saw that the mice was killed by non-virulent smooth strain of streptococcus.

After this experiment he concluded that cells contain some component later identified as DNA which can be transferred to new population of cells and transform these new cells.
