  1. Genetic variation is the difference in DNA sequences between individuals within a population. The human genome has about 3 × 109 base pairs of DNA, and between any two humans, the amount of genetic variation is about 0.1%. In other words, about 1 bp in every 1,000 bp of DNA will be different between two random individuals. Any two individuals have about 6 × 106 base pairs that are different. Therefore, we can say that there is considerable genetic variation in humans and it is important to understand every kind of genetic variation and to develop specialized techniques to analyze these variations. Only then, we can identify and relate these variations with human health and disease.
  1. Please consider our whole genome and write and briefly explain every possible type of human genetic variation that you can think of.
  2. Choose two variations from part (i) and state two different techniques to identify these two variations. Please explain briefly how these techniques can detect these variations.
  3. What may be the effect of genetic variations, if they are found in protein coding regions of genes?

Please read the two scnarious and answer the questions:

Scenario #1
Ten pea plant seeds were planted in each of 5 pots that contained 500g of “Peat’s Potting Soil.” The pots were given the following amounts of distilled water each day: Pot 1, 50ml; Pot 2, 100ml; Pot 3, 150ml; Pot 4, 200ml; Pot 5, 250ml. According to the pea seed package, the recommended of water for the pea plants was 150ml of water daily. After 40 days, the height of each plant was measured in centimeters.

Scenario #2
Sandy wanted to find out if the color of food would affect whether or not kindergarten children would select it for lunch. She put food coloring into 4 identical bowls of mashed potatoes. The colors were red, green, yellow, blue. One bowl of mashed potatoes was left as the regular white color. Each child was given the choice to choose the bowl of mashed potatoes of the color of their choice. Each day she recorded the choice of 100 different students. She did this for five days.

Please discuss about Corona virus what and what is the impact of this word on American culture? What about other cultures? Why is the history of corona virus important for us to understand? What can we gain from this knowledge? Has your research led you to believe this word will grow into something else? What will it grow into and why does that matter?

inThe citric acid cycle there are three reactions of the citric acid cycle it's self that are regulated:
-citrate synthase which is where ATP inhibits in in citeo
-isocitrate dehydrogenase: alosterrically activated by Ca2+ and ADP also is inhibited by NADH
- alpha ketoglutarate dehydrogenase which is where Ca2+ increases the rate of formation of succinyl-CoA

what would happen if all three of these reactions were not present? what would happen if citrate synthase was not functioning, what would happen if only isocitrate dehydrogenase was not working, what would happen of alpha ketoglutarate was not working?

You have discovered a new single-celled organism. Describe how you would classify it as Bacteria, Archaea, or Eukarya based on the genetics strand of cell biology. Your answer should be a couple sentences long and should include at least one tool or method you would use, the information that tool or method would provide, and what information you would expect to obtain if your organism belonged to each of the above domains.

Question 3.

Human haemoglobin is a complex protein molecule made up of four poly-peptides joined to an iron-containing haem group. In normal human adult haemoglobin, haemoglobin A, or HbA, two kinds of polypeptides designated as alpha and beta are found. Two identical alpha and two identical beta chains plus the haem group make up each molecule of haemoglobin A. Haemoglobin S, or HbS, is a haemoglobin variant occurring in individuals affected with the heritable disorder sickle cell anaemia. A comparison of the amino acid sequences of the polypeptides in haemoglobins A and S indicates that the alpha chains in the two molecules are identical, but that the beta chains differ in a single interior amino acid.

a.   How many of genes are necessary for the synthesis of haemoglobin S in an adult who is homozygous for the S allele?

b.   Assuming that the gene for the beta chain of HbS arose from the gene for the beta chain of HbA through a single mutation, what general type of mutation was most likely responsible?

c.   The difference between the beta chains of haemoglobin S and A is restricted to the sixth amino acid from the amino (-NH2) end of the polypeptide. In haemoglobin S, the amino acid at the site is valine and in haemoglobin A it is glutamic acid. From your knowledge of the genetic code (and with reference to the genetic code) what can you deduce about the specific (and simplest) base alteration in the beta polypeptide that would produce the amino acid substitution?
