Normally, this region is imprinted in the sperm, but not the egg. This means that the DNA on the ____________ copy of the chromosome will be methylated at the imprinting center, while the DNA on the ____________copy of the chromosome will not be methylated in this region.

Answers

Answer 1

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. 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.

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. Methylation modifies DNA function when found in the promoter gene, repressing gene transcription. This means that a methylated gene will not be expressed, 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.

They are both six-legged arthropods sub-grouped under the class Hexapoda (coined from the word "hexa" meaning six and "Poda" meaning leg). Their body are divided into three parts; head, thorax and abdomen.

Anaerobic respiration of yeast produces ethanol and carbon dioxide, which can be experimentally tested by determining the rate of CO2 production in a closed system.

What is anaerobic respiration?

Anaerobic respiration is a series of chemical reactions by which certain organisms can produce energy (ATP) in absence of oxygen.

Anaerobic respiration is useful in experimental settings to determine the survival rate of yeast, which can be determined by measuring the concentration of products of this process.

The experimental procedure requires the use of a closed system to determine the rate of change between reactants (glucose) and products (ethanol + carbon dioxide).

In conclusion, Anaerobic respiration can be experimentally tested by determining the rate of CO2 production.

Explanation:

A 55-year-old male is sent to your office to have an esophagogastroduodenoscopy. He is a heavy drinker and smoker who also consumes spicy foods on a daily basis. He is quite anxious about having the procedure performed and is afraid he might choke during insertion of the scope. His father and younger brother were both diagnosed with esophageal cancer. His father died, but the brother was just recently diagnosed and is taking chemotherapy.
A. List the risk factors the patient has for developing esophageal cancer.
B. How might you calm the patient's fears about the procedure?

Answers

Answer and Explanation:

A. The risk factors for this patient are age, family history, and smoking and alcoholism. That's because, most cases of esophageal cancer are detected at age 55 years. We must not forget that cancer is a disease with great genetic potential, which means that, as the father and brother of this patient had this type of cancer, this patient has a high probability of developing the same cancer. Furthermore, the constant consumption of cigarettes doubles the risk of developing esophageal cancer. This risk is also increased by alcoholism.

B. To calm the patient down, I would say that there is a very small and almost non-existent risk that he will choke or even feel the endoscopy insertion, as the entire procedure is done with the patient anesthetized and sedated.

The risk factors the patient has for developing esophageal cancer as well as how you can calm the patients fears about the procedure are as follows

A) Risk factors include

People between the age of 45 and 70 have the more risk of esophageal cancer.

If the patient has genetic signs of cancer from the past generations may have highest risk of esophageal cancer.

Males have more risk than women that is 3 to 4 times to develop esophageal cancer.

Alcohol consumption also increases the risk of esophageal cancer.

Too much weight or obesity increases the risk of esophageal cancer.

Deficiency in nutrients, vitamins and minerals can increase risk of esophageal cancer.

B) Calming the patients fears

Make the patient be happy and stress free.

Do exercise which produces mood boost endorphins that get rid of worries and stress.

Stay positive, being friendly keep good health.
