a dominant mutation in gene d can cause disease symptoms. gene d encodes an enzyme. the activity of the enzyme in homozygous normal individuals is 100%. the activity of the enzyme in heterozygotes is 25%. this observation is consistent with

Answers

Answer 1

The mutation mentioned here is a dominant negative.

Define mutation.

A mutation is a change in our DNA sequence that can be brought on by environmental factors like UV light and cigarette smoke or mistakes made when the DNA is copied.

When a mutant receptor prevents the function of the wild-type (WT) version of the receptor, the condition is known as a dominant-negative (DN) mutation.

A DN mutation generally results in a mutant polypeptide whose activity is reduced in comparison to the co-expressed wild-type protein. Dominant-negative mutations are known as antimorphs, indicating that they have the opposite impact of the gene from which they were produced, according to an early genetic study.

Oncogenes are examples of DN mutations that arise spontaneously. When only one copy of the gene is functioning, haploinsufficiency is frequently used to compare negative dominance . Since it directly affects the phenotypic diversity in this situation, the expression level of this gene is significant. Trisomy 21, which is brought on by errors in the genes producing transcription factors and other key proteins, is a classic example of a condition brought on by haploinsufficiency.

Both the central nervous system and the peripheral nervous system contain myelin, however only the central nervous system is impacted by multiple sclerosis (MS). Oligodendrocytes, a unique type of cell, create CNS myelin. Schwann cells generate PNS myelin.

what is neuron?

The two main cell types found in nervous tissue are neurons and glial cells. The cells responsible for electrical signal communication are called neurons. Supporting cells that keep the surroundings of the neurons in good condition are glial cells. Our ability to think, see, hear, speak, feel, excrete (through the bowel or bladder), and move is made possible by the neurons that make up our nervous system. The axon is insulated, protected, and helped transmit nerve signals more quickly by myelin.

Glial cells can be divided into different categories depending on which anatomical division they are located in the nervous system. There are oligodendrocytes, microglia, ependymal cells, and astrocytes in the CNS.

    The blood-brain barrier is controlled by astrocytes, which are essential for maintaining the chemical environment around the neuron. The myelinating glia in the CNS are oligodendrocytes. Microglia function as phagocytes and support immunological control.

Ependymal cells are in charge of filtering the blood to create cerebrospinal fluid, a circulatory fluid that, as a result of the BBB, performs some of the activities of blood in the brain and spinal cord. Satellite cells serve as support cells for the neurons in the PNS, and Schwann cells cushion the peripheral axons.

One of these conditions is multiple sclerosis (MS). It exemplifies an autoimmune disorder. Myelin is marked by the antibodies made by lymphocytes, a type of white blood cell, as something that shouldn't be in the body. In the central nervous system, this results in inflammation and myelin breakdown.

Scarring is visible as a result of the disease's destruction of the axon's protective covering. The white matter of the brain and spinal cord both contain many scars.

The removal of one electron from a molecule during a chemical reaction is known as oxidation.

Balancing the oxygen atom:

Oxygen has an oxidation state of -2 in oxide anions and 0 in gaseous dioxygen.

Therefore, add 4 electrons to each oxide anion in order to balance the oxidation state.

[tex]\rm2 O_2^-(aq) \rightarrow O_2(g) + 2 H_2O(l)[/tex]

Balancing the hydrogen atom:

We now have a total of 4 electrons on the left side of the equation. To balance the charge on the right side, we require 4 electrons.

[tex]4 H^+ (aq) + 4 e^- \rightarrow 2 H_2O(l)[/tex]

The result is a gaseous dioxygen molecule with a total charge of zero after we add 4 electrons to the product side.

About what mass of such material should be shipped in order that 1. 0 mg of 55cr is delivered to the laboratory?. an experimental drug has been added to a eukaryotic cell, and while the drug was designed to interfere with a membrane transport process, the investigators found that in cells treated with the drug the lysosomes quickly turned into inclusion bodies. none of the material directed to the lysosomes for removal was being digested in the lysosome, and remained intact inside the organelle. an analysis of lysosomal contents in drug-treated cells indicated that the full complement of lysosomal enzymes were present in the organelle. assuming that the drug is targeting just one protein, which one of the following proteins is most likely the target? some fiber optic communication systems use laser amplification to boost the intensity of light pulses passing through an optical fiber. a short segment of laser amplifier fiber is spliced into the main fiber so that the light pulses must pass through the laser amplifier fiber on their way to their destination. the light emerging from the laser amplifier fiber is much brighter than it was when it entered. one interesting aspect of the light emerging from the laser amplifier fiber is that it what atomic or hybrid orbital on the central i atom makes up the sigma bond between this i and an outer f atom in iodine pentafluoride, if5 ? orbital on i what are the approximate f-i-f bond angles ? (list all possible separated by a space) . if 0.00849 moles of bai makes 0.00283 moles of precipitate and 0.00630 moles of napo makes 0.00315 moles of precipitate, which reactant is limiting? Exempting things such as groceries and clothing from sales tax is an attempt by states to make sale tax less ______.
