Answer:

Gram positive and Gram negative

Explanation:

Bacteria are classified as gram positive or negative depending on whether or not they take up gram stain. The bacteria cell wall is unusual in its chemical construction .It has a strong layer of sugar polymer, cross-linked by amino acid and called *PEPTIDOGLYCAN*.

The bacteria cell wall that has a much of peptidoglycan stains *blue, and termed Gram positive*,while the *gram negative have less peptidoglycan and stained pink to red*. Example of Gram positive bacteria are Clostridium tetani, wound infecting Staphylococcus aureus(spherical),Tuberculosis-causing actinomycetes -Mycobacterium tuberculosis. Examples of Gram negative bacteria are Syphilis causing Treponema pallidum(spiral),Escherichia coli(rod), gonorrhea causing Neisseria gonorrhoeae(spherical),and Cyanobacteria.

<h3>What is Empathy?</h3>

This is defined as the capacity to understand or feel what another person is experiencing from within their frame of reference.

Normally, this region is imprinted in the sperm, but not the egg. This means that the DNA on the ____________ copy of the chromo
Nostrana [21]

Answer: The DNA on the paternal copy of the chromosome will be methylated at the imprinting center, while the DNA on the maternal copy of the chromosome will not be methylated in this region.

Explanation:

Chromosomes are DNA structures associated with proteins such as histones. They are found in the nucleus of cells and contain genetic information for the development and functioning of an organism. Human beings are diploid, meaning that they possess two copies of each of the 23 chromosomes (a total of 46).

Gametes, which are sex cells such as the sperm (produced by the male) and the egg (produced by the female) that are haploid. This means that they possess only one chromosome of each pair. During fertilization, a male gamete fuses with a female gamete to generate a zygote, which will give rise to a new human being. <u>This new individual will possess half of the genetic material from its father and half from its mother. Thus having a total of 46 chromosomes, 23 from each parent</u>.

Genetic imprinting modulates gene expression by chemical modification of DNA and/or modification of chromatin structure. Often, genetic imprinting causes a gene to be expressed only on the chromosome inherited from one of the parents. One example of imprinting is DNA methylation, which is a process by which methyl groups are added to DNA. <u>Methylation modifies DNA function when found in the promoter gene, repressing gene transcription. This means that a methylated gene will not be expressed</u>, that is, it will not produce a protein encoded by that gene. So, if a region of DNA is imprinted in the sperm cell, the paternal chromosome inherited from this sperm will be methylated in the genes of the offspring. And the offspring will only express the maternal copy inherited, which will not be methylated.
