Eva8 [605]
<span>The answer is "Meiosis".
 
Meiosis is a cell division process which forms four daughter cells which are different from parent cell. Formed daughter cells have half of chromosomes when compared to parent cells. Hence, Daughter cells are haploid (have single set of chromosomes). This process occurs in the sexually reproductive organisms and formed daughter cells can be either sperms or egg cells according to the gender of living being.</span>

What is the correct definition of antibodies?
Softa [21]

Answer: The answer is  C

Explanation:

 Antibodies or otherwise called Immunoglobulin are special protein that are produced by certain lymphocytes which produces antibodies which can affect the invading bacteria or other foreign  bodies called the antigens  or other toxins in a number of ways . Certain antibodies known as agglutinins make bacteria harmless by causing them to clump together. The lysins dissolve the outer coats of bacteria, the antitoxin neutralize the toxin of bacteria  while precipitins precipitate the toxin as insoluble and therefore , convert them to a harmless compound. Antibodies are always produced by the immune system.

Based on the definitions of pharmacophore and privileged structure, outline essential structural features a 1,4-dihyrdopyridine
stiv31 [10]

Answer:

Explanation:

Pharmacophore (pharmacology) - The molecular framework responsible for a drug's biological activity. According to IUPAC — A pharmacophore is the ensemble of steric and electronic features that is necessary to ensure the optimal supramolecular interactions with a specific biological target structure and to trigger (or to block) its biological response.

Privileged structures are defined as molecular frameworks which are able of providing useful ligands for more than one type of receptor or enzyme target by judicious structural modifications.

1) The 1,4-dihydropyridine ring is present in many biologically important molecules that acts as an important scaffold for cardiovascular drug - a calcium antagonists and although it is technically not considered as a pharmacophore, it is considered as a privileged structure.

1,4-Dihydropyridine (DHP), belongs to the class of calcium antagonist that inhibits the influx of extracellular Ca+2 through the L-type voltage-dependent calcium channels.

A positional substitution in the 4-position is feasible in the heterocyclic ring which in turn culminates in various calcium channel antagonist activities and this heterocyclic ring is the common feature for various pharmacological activities such as anti-inflammatory activity, analgesic activity,

antihypertensive, antianginal, antitumor, antitubercular activity and antithrombotic .

Position on the heterocyclic ring binds to the L-type channel and also to N-type channel on membranes.

2.) The bioisosteres are not a suitable bioisostere for the traditional C-4 aryl or heteroaryl substitution which is necessary for calcium ion blockage thereby inhibiting it to function with the mechanism shared above.
