True or false: If we extracted DNA from thyroid and neural tissues, we would find the CALCA gene in both types of cells.

Answers

Answer 1

Answer:

True

Explanation:

The calcitonin/calcitonin gene-related peptide (CALCA) gene is used to encode different peptide sequences (i.e., calcitonin hormone, calcitonin-related peptides and katacalcin) through alternative RNA splicing. These peptides have different functions. Calcitonin is a hormone mainly produced by cells of the thyroid gland, which is involved in the control of levels of calcium and phosphate in the blood. Moreover, katacalcin is a peptide synthesized from the same precursor of calcitonin (and therefore also mainly produced by cells of the thyroid gland), which is implicated in both calcium regulation and skeletal maintenance. Finally, the calcitonin gene-related peptide (CGRP) is a peptide mainly produced by sensory nerves (type Aδ fibers ), which is involved in pain pathways. The CALCA gene has attracted considerable attention from geneticists because it is specifically expressed in neuroendocrine tissues in normal conditions and abnormally induced in septic conditions (i.e., during the body's extreme response to an infection).

Explanation:

Fluorescent FM dyes partition reversibly into biological membranes without penetrating through them. Suppose that you have neurons cultured in a dish, and you incubate them with an FM dye for a period of time before washing the cells with excess medium to remove the dye.a)You find that if you stimulate the neurons to trigger action potentials during incubation with the dye, the synaptic regions of the neurons remain fluorescent after the wash. Propose an explanation for this effect.b)After you have generated fluorescent synaptic regions by this procedure, suppose that you trigger further action potentials while continuing to wash with excess medium. Would you expect the synaptic regions to lose fluorescence

Answers

Answer:

a) Emission observed is due to emission of synaptic vessels

b) Yes

Explanation:

a) Proposing an explanation

The emission observed ( the synaptic regions of the neurons remaining fluorescent ) is due to the emission on the synaptic vessels given that FM dyes have lipid-sensitive emission which can be loaded into a recycled synaptic vesicle

b)

The synaptic regions will lose fluorescence when you continue to wash with excess medium, also the more action potentials triggered the more observed emission. hence the increase in the loss of fluorescence is due to the fact that the emissions are not permanent

how do allosteric enzymes activate and inhibit chemical reactions in a living organism?​

Answers

Answer:

Allosteric activators bind to locations on an enzyme away from the active site, inducing a conformational change that increases the affinity of the enzyme's active site(s) for its substrate(s). Allosteric inhibitors modify the enzyme's active site so that substrate binding is reduced or prevented.

A child is born with hemophilia (inherited as an X-linked recessive) and Klinefelter's syndrome to parents who both have normal blood clotting. In which parent (mother or father) and during which round of meiosis (I or II) did the nondisjunction event occur

Answers

Answer:

mother  

Explanation:

Hemophilia is a sex-linked recessive disorder caused by a mutation in one of the genes responsible for encoding the clotting factor proteins (factor VIII or factor IX), which are located on the X chromosome. Moreover, the Klinefelter syndrome is caused by men having an additional X chromosome. In this case, the nondisjunction occurred from the mother because her gamete included an extra X, it is for that reason that all genes localized on the X chromosome, including the defective gene involved in hemophilia, can cause all of her sons to be affected by the disease in some generation. Thus, sister chromatids did not separate during meiosis (Anaphase II) and caused two copies of the defective allele for the hemophilia trait.

The human processes may be overwhelming the nature's ability to balance and redistribute carbon element in the environment. Thus, the correct option is B.

What are Climate changes?

Climate change are the long-term shifts in the temperature and weather patterns in an ecosystem. These shifts in the weather conditions may be natural or artificial, but since the 1800s, many human activities have been found to be the main driving force of the climate change, primarily due to the burning of fossil fuels such as coal, oil, and gas, which produces heat-trapping gases such as carbon dioxide, chlorofluoro carbons, etc.

Most of the human processes are found to be overwhelming the nature's ability to balance and redistribute carbon element in nature.

Therefore, the correct option is B.

. Luraine, who has blood type o, has a child with blood type B. She claims Will is the
child's father, but he denies this. Will's blood type is AB. How could blood typing
explain that will could, or could not be the father of this child?

Answers

Blood typing can identify if will is the father or not by the composition of the genotype and it’s compatibility within the parents.

Will can not be the parent as there is only one possible genotype composition of blood type AB being i^Ai^B.

If the mother's blood group is O and the father's blood group is AB, then the child's blood group could be A or B. Hence, Will could be his father.

What is blood group?

Blood types are based on the presence or absence of specific antigens, which are chemicals that, if they are foreign to the body, may cause an immunological reaction.

Safe blood transfusions depend on proper blood typing and cross-matching since some antigens can cause a patient's immune system to attack the transfused blood.

In case of an emergency, it is crucial to know your blood type. You'll need compatible blood if you ever find yourself in a position where you need a blood transfusion. Blood cells can cluster together due to an incompatible blood group, which can be lethal.
