The answer would be Felis silvestris lybica
Answer:
Green chemistry, or sustainable chemistry, involves creation on the molecular level:
Explanation:
During prophase, the complex of DNA and proteins contained in the nucleus, known as chromatin, condenses. The chromatin coils and becomes increasingly compact, resulting in the formation of visible chromosomes. Chromosomes are made of a single piece of DNA that is highly organized.
The given question is incomplete, the complete question is:
Raquel is having difficulty becoming pregnant, and her doctor believes it could be due to the position of her uterus. Which organ should the body of the uterus be immediately superior to in the pelvis? Multiple Choice Urinary bladder Rectum Ovary Vagina
Answer:
The correct answer is urinary bladder.
Explanation:
In the pelvis, the urinary bladder is the organ to which the body of the uterus would be immediately superior. In the pelvis or the lower abdomen, a pear-shaped hollow composition, present between the urinary bladder and the rectum is known as the uterus. The structure or the composition located superiorly lateral to the uterus body and associated with the utero-ovarian ligament is known as the ovary. The vagina and the rectum are located underneath the uterus or the uterine cavity.
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.
