The pedigree below concerns a certain rare disease that is incapacitating but not fatal. Determine the most likely mode of inheritance of this disease. Write the genotype of each family member according to your proposed mode of inheritance. If you were this family’s doctor, how would you advise the three couples in the third generation about the likelihood of having an affected child?

Answers

Answer 1

Answer:

Males are the only ones who exhibit the condition because it is X-linked and recessive (unaffected parents have affected progeny). Given that the feature is rare, it is assumed that no one possesses it.

What is pedigree analysis?

Pedigree is a family treediagram with standardized symbols. A pedigree reveals the connections between family members.

It identifies the members of a family who have particular geneticpathogenic variations, features, and diseases as well as their current health.

Because the disease is X-linked and recessive, only males can have it (unaffected parents have affected progeny). It is considered that no one has the feature because it is rare.

When one marries into the family, they inherit the recessive allele. Because the boy inherited a Y chromosome from his father, the first couple has no chance of having a child who is afflicted.

The possibility that the secondcouple will have afflicted sons is 50%, but there is no chance that they will have affected daughters.

All of the third couple'sdaughters will be carriers even though they have no chance of conceiving an impacted child.

Thus, this can be concluded regarding the given situation.

Why is a cap added to mRNA, but not to tRNA or rRNA?A-Transfer RNA and rRNA exhibit complex structures with double stranded regions. The three-dimensional shapes of these molecules keep the 5\' end of the RNA away from the enzymes that process the cap.B-Transcription and processing of mRNA occur in the nucleus, where cap binding proteins are found. These proteins, which add and modify the cap, are not found in the cytoplasm, where tRNA and rRNA are transcribed and processed.C-Each of the three types of RNA are transcribed by different RNA polymerases. Only RNA polymerase II, involved in mRNA synthesis, contains a domain capable of interacting with enzymes that form the cap.D-Only mRNA contains introns. Capping occurs simultaneously with intron removal because the same enzymes and proteins involved in both of these processes must bind to RNA at the same time.

) How many cells can be grown in a 5 mL culture using minimal medium before the medium exhausts the carbon?

Answers

Answer:

$5 * 10^(10)$

Explanation:

The question is not complete. Remaining part of the question is as follows - Minimal growth medium for bacteria such as E. coli includes various salts with characteristic concentrations in the mM range and a carbon source. The carbon source is typically glucose and it is used at 0.5% (a concentration of 0.5 g/100 mL). For nitrogen, minimal medium contains ammonium chloride (NH4Cl) with a concentration of 0.1g/100 mL

How many cells can be grown in a 5 mL culture using minimal medium before the medium exhausts the carbon?

Solution -

We will first find the mass concentration of 0.5 g/100 mL of solution.

$(0.5)/(100)$ gram per ml of glucose

The chemical formula of glucose is $C_6H_(12)O_6$

The molecular weight of glucose molecule is $180$ grams per mole

Now, we will find the number of moles of glucose in a 5 ml medium -

$((0.5)/(100) * 5)/(180) \n1.39 * 10^(-4)$ mole

The number of carbon atom in each glucose molecule is equal to six, thus, number of minimal carbon mole is equal to

$1.39 * 10^(-4) * 6\n= 8.34* 10^(-4)$ mole

Number of carbon atoms is equal to

$8.34* 10^(-4) * 6.023 * 10^(23)\n= 5 * 10^(20)\n$ Carbons

One bacteria has $10^(10)$ carbon molecule.Thus, $5$ ml medium will have $5 * 10^(10)$ bacteria

When a piece of liver is dropped into hydrogen peroxide, the peroxide bubbles vigorously as the hydrogen peroxide (H2O2) decomposes into water (H2O) and oxygen (O2) This range change in reaction rate suggeststhat liver is a substrate for hydrogen peroxide

that liver contains lots of germs

the liver contains an enzyme that breaks down hydrogen peroxide

that hydrogen peroxide is a powerful enzyme

Answers

When a piece of liver is dropped into hydrogen peroxide, the peroxide bubbles vigorously as the hydrogen peroxide decomposes into water and oxygen. This suggests the liver contains an enzyme that breaks down hydrogen peroxide. Thus, the correct option is C.

What is Catalase?

Catalase is a common enzyme which is found in nearly all living organisms which are exposed to oxygen gas. Catalase is a key enzyme which uses hydrogen peroxide, a nonradical Reactive Oxygen Species, as its substrate. Catalase enzyme is responsible for the neutralization through decomposition of hydrogen peroxide, thereby maintaining an optimum level of the molecule in the cell system which is also essential for the cellular signaling processes.

Catalase is an enzyme which causes or speeds up a reaction without being affected during the reaction. The enzyme catalase speeds up the breakdown of hydrogen peroxide into water and oxygen gas.

Therefore, the correct option is C.
