Which vector would be the best choice for cystic fibrosis gene therapy and why?

1 answer:

5 0

The vector that would be the best choice for cystic fibrosis gene therapy is adeno-associated virus for it has valuable reasons. First, it is huge enough to carry the gene, second, it will infect the right type of tissue, third, it will not cause an immune response and lastly, it infects the particular cells that divide irregularly. Therefore, this vector will definitely treat cystic fibrosis for it can target affected cells, which is a great help in the normal functioning of an organ.

Answer:

Offspring-heterozygous genotype SsEe

Explanation:

If we name the gene for the body color with S and gene for the eye color with E and if the brown body is dominant over ebony body, while red eyes are dominant over sepia eyes, than the genotypes of the parents would be: female-SSEE, male-ssee

P: SSEE x ssee

Female gametes SE, male gametes se

F1: SsEe all of the offspring would be heterozygous.

vova2212 [387]

Answer:

Connectionism is the theory that memory is stored throughout the brain in networks among neurons, several of which may work together to process a single memory.

Explanation:

Human brain is responsible for all the storage of memories. Brain stores not only memories but all the things that we desire to learn and remember. There are a lot of neurons in our brain. These neurons are responsible for flow of little electric current. This electric current is nothing but form of information that has to be stored in our brain.

The expert which is related to brain and neurons is known as neurologist. Our brain is known as master part of the body because it controls all the parts

abruzzese [7]

Answer and Explanation:

Possibly, you forgot to attach the table with the contents of each food. Therefore, I calculated the task with similar values.

1. Assume you have Food A, B, and C. Each has certain amount of Calcium, Iron, and Vit C.

Let's designate: Calcium → X oz , Iron → Y oz, vit C → Z oz

2. Assume you have following amount of Calcium in each food:

Food A = 30 mg/oz
Food B = 25 mg/oz
Food C = 20 mg/oz

3. Assume you have following amount of Iron in each food:

Food A = 1 mg/oz
Food B = 1 mg/oz
Food C = 2 mg/oz

4. Assume you have following amount of vit C in each food:

Food A = 2 mg/oz
Food B = 5 mg/oz
Food C = 4 mg/oz

Calculations:

→ You have 3 different food and each has Calcium in it. You need exactly 320mg of Calcium per day. Therefore, each food would comprise certain proportion of daily Calcium intake. We can come up with equation: 30X+25Y+20Z = 390 mg

Similarly, for iron and vitamin C, the next equations could be used:

X+Y+2Z=17 - Iron

2X+5Y+4Z=42 - Vit C

→ Now you have a system of equations:

30X+25Y+20Z = 390 (1)

X+Y+2Z=17 (2)

2X+5Y+4Z=42 (3)

→ Look for similarities! (1) and (3) seem to be similar. We can multiply the (3) by -5 to obtain: -10X-25Y-20Z=-210. We add the (1) and modified (3) equations.

30X+25Y+20Z = 390

-10X-25Y-20Z=-210

__________________

20X+0+0=180

20X=180

→ X=9 (oz of Calcium)

→ Now, we can put x=9 into equations above to ease our job:

270+25Y+20Z=390 → 25Y+20Z=390-270=120

9+Y+Z=17 → Y+2Z=17-9=8

18+5Y+4Z=42 → 5Y+4Z=42-18=24

→ Similarly, we can use Eq-s (2) and (3). We can multiply the (2) by -5 to obtain: -5Y-10Z=-40. We add the (3) and modified (2) equations.

-5Y-10Z=-40

5Y+4Z=24

__________________

-6Z=-24

Z=4

→ Z=4 (oz of vit C)

→ Now, we can take X+Y+Z=17 (2) and just put in known values(X=9 and Z=4) to obtain Y:

9+Y+4=17

→ Y=17-9-4=4 (oz of Iron)

That's all! So, if you have table values, you can just re-write the equations and doing it stepwise, as it is shown here, you can manage to calculate every value you need :)
