Identify a control group for the analysis shown in Figure 3. Justify analyzing SIRT3 protein level in four different cancer cell

Anuta_ua [19.1K]

Answer:

the control group is NS (normal stomach cells). the different cells can react different ways based on the specific cell because each cell in different people codes for different traits in each person therefore they are likely to react differently. the higher the SIRT3 expression the higher the cytoplasmic ATP levels. the difference is about 1 difference.

Duchenne muscular dystrophy is an X-linked recessive disease. A phenotypically normal couple wants to start a family. The woman’

Andreyy89

Answer:

$\frac{1}{8}$

Explanation:

From the question: Duchenne muscular dystrophy is an X-linked recessive disease.

Now for an X-linked recessive disorder to be affected by a male individual; it only requires the presence of only one copy of the recessive allele of the disease to be present BUT in a female individual. both copies of the recessive allele must be present.

Let the X-linked recessive disease(i.e Duchenne muscular dystrophy) be = (ⁿ)

However, we are told that the couples are normal and are unaffected. Therefore;

the male partner (XY) will be: $X^NY$

the female partner (XY) will be: $X^NX^N$

Similarly, the question proceeds by telling us that: the woman's brother has the disease.

Definitely, it's possible that this unaffected woman is a carrier of the disease.

So, if she is a carrier; we have her traits to be: $X^NX^n$

NOW, if a cross exist between these couples; we have

$X^NY$ × $X^NX^n$

$X^N$ $Y$

$X^N$ $X^NX^N$ $X^NY$

$X^n$ $X^NX^n$ $X^nY$

So, we have offspring as follows:

$X^NX^N$ = normal unaffected female

$X^NY$ = normal unaffected male

$X^NX^n$ = female carrier for the Duchenne muscular dystrophy disease

$X^nY$ = affected male with the Duchenne muscular dystrophy disease

So, the probability of the child to be affected with the disease = $\frac{1}{4}$

Also, the probability that the first child will be a male or a female = $\frac{1}{2}$

∴

the probability that the couple’s first child will be affected = $\frac{1}{4}*\frac{1}{2}$

= $\frac{1}{8}$

What is the main difference between catalysts <br> and enzymes?

Harrizon [31]

Answer:

Enzymes are proteins that increase (only) the rate of chemical reactions converting substrate into product.

Catalysts are substances that increase or decrease the rate of a chemical reaction but still remain unchanged.
