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.

what was the dependent variable

Answers

Answer:

Dependent and independent variables are variables in mathematical modeling, statistical modeling and experimental sciences. Dependent variables receive this name because, in an experiment, their values are studied under the supposition or demand that they depend, by some law or rule, on the values of other variables.

Biology Question

If the frequency of an autosomal dominant allele is 0.6 . Calculate the frequency of recessive phenotype in a population of 6000​

Answers

Answer:

First thing is that word “autonomous” given in the question is actually “ autosomal”.

Now let's start solution:

Frequency of dominant allele “A” is denoted by p.

Here p = 0.6

Frequency of recessive allele “a” is denoted by q.

According to Hardy - Weinberg equilibrium

p + q = 1

Hence q = 1 - p = 1 - 0.6 = 0.4

Now in question what is asked is about frequency of recessive phenotype (aa).

According to Hardy - Wienberg equilibrium frequency of recessive phenotype is q2 (q square).

Frequency of recessive phenotype is = q2 = 0.4 x 0.4 = 0.16

Now Number of recessive phenotype in a population of 10000 is

= frequency of recessive phenotype x total population

= q2 x 10000

= 0.16 x 10000

= 1600

Mutations in which of the following cells would get passed on to the next generation?
I. sperm
II. Skin cell
III. Egg
IV. Neuron
A. II, III, and IV
B. III only
C.I and III
D. I, III, and IV

Answers

Answer:

C. I and III

Explanation:

A mutation needs to occur in a gamete cell in order to be passed down to the next generation.

If it occurs in a somatic (body) cell, the mutation will only be present in that organism.

On the other hand, in a gamete cell, the mutation will pass down because gamete cells are directly involved in the genetic makeup of the offspring.

So, since sperm and egg cells are gametes, mutations in those cells would get passed on.

The correct answer is C. I and III

What are the properties of a compound ?

A compound composed up of two or more elements which are chemically combined with a fixed proportion by their mass.

For example, Water, Sodium Chloride,  Ammonium Chloride etc.

They have fixed melting and  boiling points.

Formation of compound is a change in chemical reaction and the components of compound are mixed in a fixed proportion.

Two major types of compounds are covalent and ionic compounds.

Covalent compounds refers to formation of covalent bond among two nonmetals, like water or methane. These molecules are neutral and weak.

When metal react with non metal it form Ionic compounds, are held together by opposite charges, so the bond is stronger than covalent compound.
