Joe and Angie Summers would like to know how their daughter Jane has PKU whe
her brother Josh does not. They do not understand how neither of them could have
PKU and then have a daughter who does.
Your task is to help Joe and Angie understand how this has happened and the
likelihood it will happen again if they have another child.
Write a letter to Joe and Angie Summers explaining how the PKU trait was passed
down to their daughter, Jane.
Your role: Genetics Counselor
Audience: Joe and Angie Summers
Format: A formal letter
PKU is an autosomal recessive condition that is transmitted from parents to their progeny. Joe and Angie are heterozygous (Pp) and express the normal phenotype, but are carriers. They have 75% chances of having a healthy child, and 25% chances of having a child with PKU. Jane has PKU because both of them transmitted the recessive allele.
Note: I will provide an explanation of what PKU is, and how the cross between Joe and Angie occurs. After that, you will need to write the formal letter.
What is PKU?PKU is an inherited condition coded by a somatic recessive allele. PKU means Phenylketonuria that causes a natural increase of phenylalanine in blood. If it is not correctly treated it can lead to severe damage.
Phenylalanine is an amino acid that is converted into other substances necessary for the organism by the enzyme phenylalanine hydroxylase. In the absence of this enzyme, the amino acid increases its level in the blood.
The somatic gene PAH is responsible for the enzyme phenylalanine hydroxylase production. The mutated form of this gene -recessive allele- leads to the lack of enzyme production or the alteration of its functions, and hence, the increase in Phenylalanine levels.
PKU is transmitted by the recessive allele of PAH.
Two parents that are heterozygous for this trait express the normal phenotype but might have a child with PKU. This is because both parents transmit the recessive allele to their child, and so, the baby is homozygous recessive and expresses the condition.
Let us assume that
P is the dominant allele that codes for the normal enzymep is the recessive mutated allele that codes for the altered enzymeJoe and Angie are bothe heterozygous for this trait ⇒ Pp. They express the normal phenotype but are carriers.
Parentals) Pp x Pp

F1) Expected Genotype
There are 25% of chances of having a homozygous dominant child PPThere are 50% of chances of having a heterozygous child PpThere are 25% of chances of having a homozygous recessive child ppExpected phenotype
There are 75% chances of having a normal child (PP + Pp)There are 25% chances of having a child with PKU (pp)Every time Joe and Angie have a baby, they have 75% chances of having a healthy baby, and 25% chances of having a baby with PKU.
Baby Jane was among this 25%. She inherited two recessive alleles from her parents.Jane's bother was among the 75%. He inherited at least one dominant allele from his parents.In the letter you must explain,
This is a recessive autosomal condition, Joe and Angie must be heterozygous and this is why neither of them could have PKU, but can transmit it. Depending on the alleles they transmit to their progeny thay can have healthy or affected children. Healthy children inherit at least one dominant allele, while affected children only inherit recessive alleles. Baby Jane only recesived recessive alleles from them, so she is homozygous recessive and expresses PKU.Jane's brother has at least one dominant allele, and can be homozygous dominant or heterozygous. This is why he is healthy. The likelihood of having another affected child again is 25%, versus 75% of having a healthy child.You can learn more about PKU at

Tom40 is partially translocated through the outer membrane and is then transferred in the plane of the membrane to fold into its native conformation. true or false
Tom40 is partially translocated through the outer membrane and is then transferred in the plane of the membrane to fold into its native conformation. The given statement is true.
Tom40 is a protein that is found in the outer mitochondrial membrane. The TOM complex is responsible for the translocation of preprotein into the mitochondria. The translocation of Tom40 is similar to that of other mitochondrial proteins. The TOM complex recognizes the sequence of Tom40, which is cleaved by a matrix-processing peptidase to generate a mature protein. The partially translocated Tom40 then moves laterally in the membrane to fold into its native conformation.
The translocation of Tom40, like many mitochondrial proteins, is a complex process that involves several factors and translocation machinery. This process is important for the correct localization and function of mitochondrial proteins, including Tom40. Therefore, the given statement that Tom40 is partially translocated through the outer membrane and is then transferred in the plane of the membrane to fold into its native conformation is true.

The can of soup has 300 mg of sodium and pop Tart has 0.5 g of potassium while on the other hand, honey nut, frosted flakes, Oreos and pop Tarts has 0.14 g, 0.12 g, 0.3 g, and 0.35 g of potassium respectively and can of soup, honey nut, frosted flakes and Oreos has 190 mg, 150 mg, 80 mg, and 180 mg of potassium respectively which is lower than pop Tart so we can say that less amount of pop tart provides more potassium. 9579 of soup and 7505 of pop Tart are the masses required for I mole sodium and potassium.
Skin is classified as either thick or thin based on two parameters: the number of epidermal ____ in the epidermis and the relative _____ of the epidermis, rather than the thickness of the entire integument
Skin is classified as either thick or thin based on two parameters: the number of epidermal layers in the epidermis and the relative thinness or thickness of the epidermis, rather than the thickness of the entire integument.
Thin skin has a thinner epidermis with fewer layers of cells than thick skin. Thin skin is found in areas of the body that are not subjected to as much mechanical stress or abrasion, such as the face, neck, and upper limbs. Thick skin has a thicker epidermis with more layers of cells and is found in areas of the body that are subjected to mechanical stress or abrasion, such as the palms of the hands and soles of the feet.
In addition to the differences in the thickness and number of layers in the epidermis, thick and thin skin also differ in the distribution of hair follicles and sweat glands. Thick skin has no hair follicles or sebaceous glands, but it does have a large number of sweat glands, which help to regulate body temperature. Thin skin, on the other hand, has hair follicles and sebaceous glands, but a lower density of sweat glands.

Determine if the process is an example of anabolism or catabolism. French fries are digested in the intestine, breaking them into smaller molecules A body builder exercises to build muscles through protein synthesis A child eats a milkshake, which provides her with energy Process Catabolism
Answer:
--> French fries are digested in the intestine, breaking them into smaller molecules.(Catabolic process)
--> A body builder exercises to build muscles through protein synthesis. (Anabolic process)
--> A child eats a milkshake, which provides her with energy (catabolic process).
Explanation:
CATABOLISM is the process by which living organisms break down large or complex molecules into smaller molecules with the release of energy for their own use. Foods that we consume contains different nutrients which includes carbohydrates, fats &oil, and protein. These nutrients are made available for our body cell use and maintenance through the process of catabolism. Through catabolic processes, these nutrients are broken down into its smaller constituents with the release of energy which is used immediately to power molecular machines that support cell, tissue, and organ function. The following are examples of a catabolic process as it involves breakdown:
--> French fries are digested in the intestine, breaking them into smaller molecules and
--> A child eats a milkshake, which provides her with energy
In contrast, anabolic process involves the building up larger molecules from smaller ones. It uses ATP molecules generated by catabolic reactions as a form of energy to create new molecules that form new cells and tissues, and revitalize organs. For example, muscles can be built from the synthesis of proteins. This is also called anabolic training.
French fries are digested in the intestine, breaking them into smaller molecules - Catabolic process
A body builder exercises to build muscles through protein synthesis - Anabolic process
A child eats a milkshake, which provides her with energy - Catabolic process
Catabolism can be defined as the break down of larger molecules into smaller ones in a series of metabolic pathways of which the energy produced undergoes oxidation and then is released or it is used in another reaction. Digestion is an example of a catabolic process i.e. French fries are digested in the intestine, breaking them into smaller molecules. A child eating a milkshake, which provides her with energy (energy is produced) is a catabolic process.
Anabolism involves the build up of molecules from smaller molecules usually needed for bodily functions. Protein synthesis is an anabolic process (buildup from small amino acids to large proteins. A body builder exercises to build muscles through protein synthesis is an example of anabolism
