a transmembrane segment of a membrane protein is all made up of alpha helix and contains 22 amino acids. what is the thickness o

f the membrane? if the transmembrane segment was made up of beta strand then how many amino acids in that beta strand will be needed to travel through the thickness of the membrane?

Nine amino acids are needed to travel through the thickness of the membrane.

Alpha-axial helix's distance between amino acids is 1.5. A

The number of gaps between the 22 amino acids in the helix is equal to (22-1) = 21.

Therefore, the helix's length is (21 X 1.5) = 31.5.

One alpha helix is sufficient to span the membrane's breadth, hence the formula is: span of the helix = thickness of the membrane = 31.5 A

The thickness of the membrane is determined by the formula above to be 31.5 AA.

In the beta-strand, there is 3.5 AA between each amino acid.

Therefore, (31.5/3.5) = 9 amino acids are needed.

A patient has taken levodopa [Dopar] for Parkinson's disease for 2 weeks but reports no improvement in the symptoms. Which respo
Elan Coil [88]

Answer:

Option-D

Explanation:

Parkinson's diseases are a neural disorder which affects the movement of the human body. The disease is caused by the low production or no production of dopamine by the neurons which thus interfere with the impulse transfer and thus movement.

In the given question, the patient with Parkinson's disease is provided with levodopa but no improvement is observed therefore the prescriber must change the drug regimen, for example, the levodopa should be given in combination with carbidopa. These medications enter the blood-brain barrier and get converted to the dopamine.

Thus, Option-D is the correct answer.

Two organisms that have sexual and two that have asexual reproduction?
Ipatiy [6.2K]

Answer: Sexual reproduction: rabbits and dolphins.

Asexual reproduction: Strawberry and potato.

Explanation:

  • Sexual reproduction is carried out with the participation of germ cells from two stem organisms - female and male, which transfer the properties of the inherited material to the new plant. The main characteristic of sexual reproduction is the division of the relative fusion of male and female sex cells. The end product of this relationship is the creation of an organism that contains the genetic information of both parents.
  • Asexual reproduction is a habit that produces an organism identical to the parent organism, and we call this product clones. This form of reproduction does not involve the germ cells and may occur by division or budding. Many types of plants reproduce in this way. So the strawberries are propagated by boils, and the potatoes are buds from the tub

Fill in the Punnett square below to visualize the offspring of a cystic fibrosis carrier and a person who doesn't have cystic fi
valkas [14]

Answer:

50% of their children are likely to be carriers of cystic fibrosis

Explanation:

Since the normal allele "F" will be the dominant allele while the mutated CFR allele "f" will be the recessive allele, <u>the gene (pair of alleles) of the person that is a CFR carrier will be "Ff" while that of the normal person who isn't a carrier will be "FF"</u>. The attachment shows the crossing between the two parents. From the illustration in the attachment, for every 4 children given birth to, 2 of them will likely be normal, "FF", (not a carrier and doesn't have cystic fibrosis) while 2 others will likely be carriers of cystic fibrosis (Ff). Hence, 50% of their children are likely to be carriers of cystic fibrosis.
