Suppose you have monohybrid snapdragons in your garden and you find that they produce red seeds to white seeds in the ratio of 3:1. If the alleles are designated R (red seeds) and r (white seeds), what are the probable phenotypes of the parents (P1)?

Answers

Answer 1

Answer:

Parents are both red-seeded (Rr)

Explanation:

The gene involved here is that of seed colour in snapdragons. Red allele (R) and white allele (r) are the two forms of the colour gene. According to the question, the offsprings are in the ratio 3red:1white. This ratio means that there are 3 red-seeded offsprings and 1 white-seeed offspring.

Based on this, the red allele (R) is dominant over the allele for white (r). This means that the red trait can be expressed in a homozygous or heterozygous state while the white trait can only be expressed in a homozygous state. Hence, this 3:1 ratio can only be experienced if both parents (P1 generation) are heterozygous.

This would produce offsprings with genotype: RR, Rr, Rr, rr

RR, Rr, and Rr are all phenotypically red while rr are phenotypically white

Answer 2

Answer: They parents would both be "half red and half white" making them heterozygous or Rr and Rr
Since when put into a punnet square it produces the 3:1 result

Consider this reaction:PCl5(g) + heat PCl3 (g) + Cl2 (g)
What will happen when the pressure is decreased?
There will not be a shift in equilibrium.
There will be a shift toward the products.
There will be a shift toward the reactants.
There is not enough information to make a prediction.

Answers

The answer is There will be a shift toward the products.

To solve this problem, it is necessary to understand Le Chatelier's principle. According to the principle, if a chemical reaction undergoes changes in conditions, the chemical equilibrium will shift in order to undo the effects. In the reaction PCl5(g) + heat ↔ PCl3 (g) + Cl2 (g), when pressure is decreased, the system will try to increase it. This will result in the increase of gaseous pressure, so the equilibrium will be shifted toward the products.

What happens after genetically modified plasmids are inserted into bacteria?

Answers

The answer to the question is: Once a new DNA is inserted, the modified plasmid can be grown in bacteria for self-replication to make endless copies.
>The plasmid is genetically modified to produce 1 or 2 specific proteins from a pathogen and then purified for immunization.

>A plasmids are small double-stranded unit of DNA.They are usually circular but sometimes linear, that exists independent of the chromosome and is capable of self-replication. Each plasmid carries only a few genes.

The function of glycogen phosphorylase is: question options: a. the conversion of glucose-1-phosphate to glucose-6-phosphate.
b. inhibit the production of glucose-1-phosphate.
c. to breakdown atp.
d. stimulate the buildup of glycogen.
e. catalyze the phosphorolysis of glucose-1-phosphate from glycogen molecules.

Answers

Answer:
The correct option is e (catalyze the phosphorolysis of glucose-1-phosphate from glycogen molecules).

Reason:
It is that type of enzyme which is responsible for the conversion of glycogen into glucose through a series of reactions. First of all glycogen is converted to glucose 1-phosphate catalysed by glycogen phosphorylase. It is then converted into glucose 6-phosphate with the help of phosphoglucomutase. In liver it is then converted into glucose which enter into blood stream.
I hope it will help you. If not then look at diagram you will easily understand the phenomenon.

Final answer:

Glycogen phosphorylase catalyzes the phosphorolysis of glucose-1-phosphate from glycogen molecules, playing a critical role in the process of glycogenolysis. It helps in the conversion of stored glycogen into glucose for use as energy by the body.

Explanation:

The function of glycogen phosphorylase is to catalyze the phosphorolysis of glucose-1-phosphate from glycogen molecules. What this means is that it helps to break down glycogen, a form of energy storage in animals, into glucose-1-phosphate. In other words, glycogen phosphorylase plays a critical role in the process of glycogenolysis, which is the process of converting stored glycogen into glucose for use as energy by the body. It does this by adding a phosphate group to the glycogen molecule, creating glucose-1-phosphate, which can then be converted into glucose-6-phosphate and ultimately used to generate ATP, the cell's primary energy currency.

Which of the following is an example of gene cloning

Answers

Gene cloning is the process in which a gene of interest is located and copied (cloned) out of DNA extracted from an organism. It is a common practice in molecular biology labs that is used by researchers to create copies of a particular gene for downstream applications.

A good example of gene cloning would be, breeding 2 dogs that are the same breed and have good characteristics to have similar outcome.
