Isotonic contraction of a muscle produces a movement at the joint of the muscle with the bone, the insertion end of the muscle moves relative to the point...

Many parts of skeletal system first develop as soft cartilage for the functional purpose:  such flexibility of fetus for passage through birth canal.    Eventually, the neonate (new born) develops and becomes stronger. During this phase chondroblast stop differentiating int...

Phyllis,   it depends on the type of stem cells: totipotent, pluripotent, multipotent or committed progenitor stem cells. Here is what I teach in the class room: Totipotent Stem Cells Capable of generating an entire organism Capable of generating embryonic and extra-embryonic...

Hi Angelica,   Gut microbiome is an important indicator of number of physiological functions (digestion, susceptibility to infection, allergic reactions etc.); it comes under environmental selection pressure and is being considered significant for bio-marker analysis during certain...

Somatic mutations are acquired through exposure to mutagens in somatic cells of the body.   They will not be inherited unless a similar damage has happened in eggs or sperms due to the same exposure to mutagen, In that case, progeny might show the mutation.     Since...

Casey,   Physiology is function and its mechanism/pathway that leads to completion of function.   You may start with the biological function that you find most intriguing, learn the organ systems and organs involved in  this function, then their structural variation...

Second part of the question appears to be a trick, coding strand is never  3’-xxx-5’   TGG.CAA.TTT.GTA Trp, Gln, Phe, Val,   TGC.CCG.TTA.GTA Cys, Pro, Leu, Val GTG.TAC.ATA.GTA Val, Tyr, ile, Val   Best

Please make a punnet square:     Parental genotypes are S/s  for both parents since they are heterzygous.            S            s  S      SS         Ss     s ...

Nucleus is the site of chromatin and chromosomes both.   Cell during resting phase/interphase or S1/S2, G1/G2 only has chromatin.   During M phase or at onset of cell division, chromatin unwinds and chromosome become apparent.   Chromatin is made of DNA wound...

DNA ladder markers that are commonly used are 123 bp ladder and 1 kb ladder. I do not know which one you are using.    pBluescript is about 3 kb and therefore plasmids with insert size 125, 564, 2027, 2322, will be as follows:   3.1 kb, 3.5 kb 5 kb  5...
