Explanation:
when does mutation have the greatest effect; translation, RNA synthesis, DNA Replication or somatic cell formation?
Answer:
It depends on the specific cell type that suffers the mutation. For example, in stem cells, it is reasonable to expect that mutations in the genes involved in DNA replication will have critical consequences
Explanation:
A mutation is a genetic modification in the DNA sequence due to errors during the mechanism of DNA replication or by the effects of environmental (mutagenic) factors. A mutation in the germline can be inherited in the next generations, while a mutation in somatic cells is not inherited. Moreover, a mutation affecting RNA synthesis may have diverse effects depending on the function of the gene involved in this mutation. In a similar mode, a mutation in one gene associated with the mechanism of DNA replication can have critical consequences on the cells originated from the mutated parental cell, but again it is variable and generalizations can not be made without knowledge of the cell type suffering this modification.

When glycogen phosphorylase is phosphorylated Group of answer choices its activity decreases. its activity increases. its activity is unaffected. none of these because that enzyme doesn't get phosphorylated.
Answer:
The correct answer is that its activity increases.
Explanation:
Glycogen phosphorylase comes under the category of phosphorylase enzymes. The mentioned enzyme catalyzes the rate-limiting step in the process of glycogenolysis within the animals. The sequential phosphorolysis of glycogen to discharge glucose-1-phosphate is catalyzed by the enzyme glycogen phosphorylase. Therefore, glycogen phosphorylase plays an essential part in the use of liver and muscle reserves of glycogen. After undergoing phosphorylation, the activity of the enzyme increases.

A farmer plants Bt cotton that is genetically modified to produce its own insecticide. Of the cotton bollworms feeding on these Bt plants, only 8% survive unless they have at least one copy of the dominant resistance allele R that confers resistance to the Bt insecticide. When the farmer first plants Bt cotton, the frequency of the R allele in the cotton bollworm population is 0.4. What will the frequency of the resistance allele be after one generation of cotton bollworms fed on Bt cotton
Answer:
0.6
Explanation:
According to hardy-weinberg principle,
P2+2pq+q2=1
P+q=1
q=1-p
Given that Allele R frequency is 0.4
and p represent the dominant allele
P=0.4
P2=0.4^2 = 0.16 for genotypic frequency
Since p+q=1
q=1-p
where q stands for recessive allele r frequency and q2 stands for genotypic frequency for allele r
q= 1-0.4= 0.6
q2=0.6 ^2
q2=0.36
Hardy-Weinberg principle states that are used to calculate the genetic variation of a population at equilibrium.
The frequency of the resistance allele in the cotton bollworm is 0.6.
Hardy-Weinberg equation can be given as:
P² + 2PQ + Q² = 1
where,
P = dominant allele (R)
Q = recessive allele (r)
Frequency of R allele = 0.4
From the equation:
P + Q = 1
or,
Q = P - 1
Genetic frequency of the R allele = P² = 0.4 x 0.4 = 0.16
Substituting the values:
Q = 1 - 0.4
Q = 0.6
Q² = 0.36
Thus, the frequency of the resistance allele will be 0.6.

Drag each label to the correct location. Each label can be used more than once. In a hydropower station, water stored in dams is allowed to fall with force to make a turbine move. The turbine moves and produces electricity. In the diagram, identify the stages of transformation of energy in the hydropower station. Please help!!
Answer:
Stored water - gravitational energy
Water fall - kinetic energy
Turbine - kinetic energy
Powerlines - electric energy
Explanation:
Dams are used to store or hold water for hydroelectric power plants. This stored water which has gravitational energy is a form of potential energy.
When the water is left to fall and run fast through the turbine, the gravitational energy is transformed into kinetic energy which makes the turbine to spin.
As the turbine spins, kinetic energy that is produced also powers the shaft of the engine in the electric generator, which produces electricuty.
Kinetic energy is transformed to electric energy and transmitted along powerlines.
