What are the features of Nuclear Receptor Screening Services?

Nuclear receptors (NRs) are a class of proteins responsible for thyroid hormones and sensing steroid and certain other molecules. There are 48 genes in the human genome that code for the NRs. As the largest family of eukaryotic transcription factors, NRs control numerous processes involved in development, cell cycle, and important metabolic pathways.

https://dda.creative-bioarray.com/nuclear-receptor-screening.html

Answers

Answer:

The nuclear receptor superfamily comprises a large group of transcription factors that play a key regulatory role in development and homeostasis of multicellular organisms. A special feature of nuclear receptors is their ability to bind to condensed chromatin templates, which makes them important initiators of gene transcription. Moreover, the ability of nuclear receptors to sequentially recruit a variety of transcription factors and coregulators to target promoters and to orchestrate the whole process of gene transcription confirms their biological significance and stimulates intensive research and a high level of scientific interest in this field. In this review, we summarise current knowledge regarding the structure and function of nuclear receptors as principal regulators of gene expression. Emphasis is given to the molecular mechanisms of nuclear receptor-mediated transcriptional activation and repression including recent progress made in this area.

The process by which dissolved gases are exchanged between the blood and interstitial fluids is Select one: a. cellular respiration. b. diffusion. c. external respiration. d. breathing. e. pulmonary ventilation.

Answers

Answer:

b. diffusion.

Explanation:

Diffusion can be defined as the movement of gas molecules from a region of high concentration to a region of lower concentration until an equilibrium is attained or reached. This mixing of gas molecules in the liquid or gaseous state is due to their kinetic energy of random motion i.e without requiring bulk motion.

This ultimately implies that, diffusion is a phenomenon through which gas molecules in either a gaseous or liquid state spread out in response to a concentration gradient, which is simply the difference in concentration of the gases across a space.

During diffusion, molecules move from areas of high concentration to areas of low concentration.

In this context, the process by which dissolved gases are exchanged between the blood and interstitial fluids is referred to as diffusion.

On a related note, this process is also referred to as internal respiration because it involves the exchange of oxygen gas and carbon (II) oxide gas between tissue cell and capillaries.

All of the following statements about ferns are correct except:_________
A) ferns flourish in many habitats, but the majority are located in the tropics.
B) the sporophyte is a conspicuous generation.
C) sori are located on the back or ventral surface of fronds.
D) the gametophyte is a conspicuous generation.
E) ferns have underground stems called rhizomes.

Answers

Answer: B) because in higher plants, such as angiosperms and gymnosperms, the sporophyte is the dominant generation.

All of the following statements about ferns are correct except the gametophyte is a conspicuous generation. Therefore, the correct option is D.

In ferns the gametophyte is usually much smaller and less noticeable, whereas the sporophyte is the more noticeable generation. The sporophyte, the famous giant pearl fern plant, is a major stage in the fern life cycle. Gametes (eggs and sperm) are produced by the gametophyte, which is a small, autonomous stage responsible for sexual reproduction.

Therefore, the correct option is D.

An ecologist counted the number of eggs in randomly selected nests in a population of birds. To test the hypothesis that the number of eggs per nest follows a Poisson distribution at the 5% level of significance, you will need to compare a calculated value with a critical value.
Eggs Number of nests Prob Expected
nest, xi per fi
0 15 0.2845 19.9
1 29 0.3576 25.0

a. calculated = 45.6; critical = 5.991.
b. calculated = 3.10; critical = 5.991.
c. calculated = 5.89; critical = 5.991.
d. calculated = 3.10; critical = 7.815.

Answers

Answer:

d. calculated = 3.10; critical = 7.815.

Explanation:

To test the hypothesis Given in the question above, we use the Chisquare goodness of fit :

The test statistic is defined as :

χ² = Σ(Observed - Expected)² / Expected

Observed = number of nests

χ² = ((15 - 19.9)^2 / 19.9) + ((29 - 25)^2 / 25) + ((19 - 15.7)^2 / 15.7) + ((7 - 9.3)^2 / 9.3)

χ² = 3.1089

The critical value :

df = n - 1 = 4 - 1 = 3

The critical value ;P(χ² at 0.05, df = 3 ) = 7.815

B. The differentiation of helper T cells into cytotoxic T cells to destroy pathogens.
C. The production of macrophages to use phagocytosis on pathogens.
D. The differentiation of effector B cells into plasma cells to make antibodies.

Answers

The Cell-mediated response results in the production of macrophages to use phagocytosis on pathogens. The correct option is C.

Cell mediated immune response occurs when an invading antigen causes the release of cytokines (Interleukins), differentiation of T cells and production of macrophages.

Macrophages are produced through the differenciation of monocytes. They are further activated during an infection through the macrophage-activating cytokine (Interleukins).

Phagocytosis is the process used by immune cells such as macrophages  which involves ingesting and eliminating pathogenic microorganisms.

Cell-mediated response dosent result to differenciation of helper T cells into cytotoxic T cells rather it leads to the activation of cytotoxic T cells. Therefore B is wrong.

Cell-mediated response dosen't lead to the production of antibodies therefore option D is wrong.

B. GGACTCGATCTTC
C. GGACCGTCGATCTTC
D. GGACCGTCGATCCTT
Reset Selection



ASAP

Answers

Answer:

D. GGACCGTCGATCCTT

Explanation:

Mutation refers to any change in the nucleotide sequence of a gene. Mutation can be of different types depending on how it occurs. According to the question, an INVERSION mutation is a type of mutation in which a segment of a gene gets broken off and reattached in another way on the same DNA. Hence, the only change in inversion mutation is the arrangement of the nucleotide bases on the gene.

Considering the nucleotide sequence: GGACCGTCGATCTTC, the sequence that describes an occurrence of inversion mutation is: GGACCGTCGATCCTT because the segment TTC in the original sequence has been rearranged as CTT in the mutated sequence.

What are Lipids?

Lipids are defined as a broad group of naturally occurring molecules that include fats, waxes, sterols, fat-soluble vitamins, monoglycerides, diglycerides, phospholipids, and others. Important functions of lipids include storing energy, signaling and serving as structural components of cell membranes.

A lipid is a type of organic compound that is insoluble in water that includes fats, waxes, oils, hormones, and some components of membranes and serves as energy-storing molecules and chemical messengers.

When we arrange the elution on the basis of charge, triglyceride and cholesterol have no charge placed on first and second respectively, while sphingosine has 1 charge. and phosphatidyl serine and sphingomyelin have more than 2 charges

Thus, the lipids in order of elution by placing the first lipid to elute at the top are as follows:

Animals have special features that help them to live in a particular place. Therefore this features is called adaptation.

1] Aquatic plants have leaves that float on the surface of water.

2] Thier leaves are rarely have stomata.

3] Thier leaves can perform all the work without xylem.

4] They are usually lack cuticle layer in order to avoid excessive dryness.

Answer:

The most common adaptation is the presence of lightweight internal packing cells, aerenchyma, but floating leaves and finely dissected leaves are also common. Aquatic plants can only grow in water or in soil that is frequently saturated with water.

Four characters of aquatic plants are as given below:

1) most aquatic plants donot need culticles or have thin culticles as cuticles prevent loss of water.

2) aquatic plants keep their stomata always open for they do not need to retain water.

3) on each side of their leaves are a number of stomata.

4) aquatic plants have less rigid structure since water pressure supports them.
