Answer:

The correct answer is d) genomic imprinting.

Explanation:

Genomic imprinting is a biological process by which specific modifications in the germ line that produce differences in the expression of the genetic material that is biochemically marked indicating its parental origin. The Prader-Willi syndrome is one of the best known and most studied examples in relation to pathologies produced by genomic imprinting. Prader-Willi syndrome is a complex genetic disease that is fundamentally neurological. Its appearance is due to a deletion of a fragment of chromosome 15 derived from the father.

Answer:

number of protons = 48

number of neutrons = 64

number of electrons = 48

Explanation:

The mass number of an atom is the sum of the number of protons and neutrons in the nucleus of the atom. Hence, for Cadmium;

mass number = proton number + neutron number = 112

Cadmium has an atomic number of 48. The atomic number is the number of protons found in the nucleus of the atoms of an element. Hence, the number of protons in an atom of Cadmium is 48.

proton number + neutron number = 112

proton number = 48, hence

48 + neutron number = 112

neutron number = 112 - 48 = 64

Also, for a neutral atom of an element, the number of protons and electrons must balance. This means that for a neutral atom of Cadmium with a proton number of 48, the number of electrons will also be 48.

In summary, for cadmium:

number of protons = 48

number of neutrons = 64

number of electrons = 48

The mass number of an atom can be seen as the sum of the number of protons and neutrons in the nucleus of the atom. And the number of protons is always the same as the number of electrons

The number of protons = 48

The number of neutrons = 64

The number of electrons = 48

 Since the mass number = proton number + neutron number = 112.

And cadmium has an atomic number of 48.

The atomic number is the also regarded as the number of protons found in the nucleus of the atoms of an element.

Then the  number of protons in an atom of Cadmium is 48.

Since proton number + neutron number = 112

    48 + x = 112

    x = 112 - 48 = 64

Therefore the number of neutron is 64.

Families are generally from the same background and culture. They usually take the therapy due to various reasons such as lack of communication among family members, inappropriate behaviors of children, or any type of change in family dynamics.

The language of all members is normally similar so it can not be a reason for barriers among family members and they require therapy.

Explanation:

In cellular respiration, glucose is fully oxidized, while in fermentation, glucose is not fully oxidized and regeneration of NAD+ is occurred.

Similar to burning, cellular respiration causes the full oxidation of glucose into CO2 and water. Contrarily, fermentation only partially oxidizes glucose.

In fermentation: lactic acid is produced from glucose in the absence of oxygen.

Cellular respiration: pyruvate is the product of glucose oxidation in the presence of oxygen.

Instead, waste is created in the form of tiny, reduced organic molecules. Because of this, cellular respiration uses glucose more efficiently than fermentation to release energy.

Therefore, in cellular respiration, glucose is fully oxidized, while in fermentation, glucose is partly oxidized.

Directly deposited sediments by water are often sorted and show layers, of the sediments left behind by glaciers, hence option D is correct.

Additionally, it appears that the glacier debris is unsorted a diamictite, a sedimentary rock made up of unsorted grains, is produced when this mass of sediment is cemented into a rock.

Till is the name for the loose silt in its unlithified state, they are distinguished by a lack of stratification and a diverse variety of sediment sizes, ranging from boulders to clay.

Therefore, a tillite is a more precise term for an unsorted sedimentary rock that contains grains that were deposited by ice, hence option D is correct.

The two ways by which we can detect that gene editing have occurred in the bacteria are;

A) WESTERN BLOT; Here,the gene that is edited will not be able to synthesize the protein.With this,if we do western against the already edited protein,no band will eventually appear in the western blot,and this indicates/confers that the gene have been edited.

B) PCR FOLLOWED BY SEQUENCING; IN PCR,there is amplification of the region with the use of flanking end primers that is edited.

However,mean primers will actually be used in a way that one primer is upstream to site of editing and the other primer to the downstream.

From this stage,the PCR product that is amplified will be sent for sequencing,and this sequency result will further confirm if the gene has been edited or not edited.

Restriction enzyme can also be used if the place where the gene has been edited is known.

If actually the gene has been edited,the nucleotide sequence will get changed.Having to choose such enzyme that cut only one's wide type wild type DNA but not actually gene that is edited,the result will further be compared inorder to confirm whether the gene has been edited or not.

The two experiments that can be done to detect gene editing including

Western blot and PCR(polymerase chain reaction)

DNA contain all the genetic properties of a cell and comprises of nucleotides with unique protein(amino) sequences. Western blot helps to detect specific protein through the sequences from a protein sample and helps to detect if editing took place.

Polymerase chain reaction(PCR) helps in the amplification of DNA which

helps to verify where editing took place if any.

Answer:

b. Forward or reverse primers

Explanation:

Sanger sequencing is a technique of DNA sequencing based on the extension of DNA fragments with variable sizes terminated with dideoxynucleotides at the 3′ end. This technique was developed by Frederick Sanger in 1977. In Sanger sequencing, a short primer is added in order to bind by complementarity to the target DNA region of interest. Subsequently, a DNA polymerase adds nucleotides (A, T, C and G) in the 5'-3' direction. Finally, the extension of the DNA strand is stopped by adding dideoxynucleotides, which are nucleotide analogs (i.e., modified nucleotides) that act as DNA synthesis terminators.

When setting up a Sanger sequencing reaction, each reaction should include template DNA, nucleotides, dideoxynucleotides, buffer, DNA polymerase, and forward or reverse primers.

Sanger sequencing refers to a laboratory procedure that's used in the determination of DNA sequence by using dideoxynucleotides. Sanger sequencing is also known as dideoxy sequencing.

For Sanger sequencing to work, one needs two pieces of information that will be used to apply the strategy of sentence game to the sequencing of DNA. It should be noted that forward or reverse primers are required for the reaction.
