Protein structure

... linked through peptide bonds into a chain. Within and outside of cells, proteins serve a myriad of functions, including structural roles (cytoskeleton), as catalysts (enzymes), transporter to ferry ions and molecules across membranes, and hormones to name just a few. With few exceptions, ...

Molecular gene (genome) concept scientifically untenable

... events leading to changes in cell shape followed by cell death. These changes in cell shape include blebbing, which occurs when a portion of the cytoskeleton separates from the plasma membrane and creates an irregular bulge called a bleb. This is like the locking of a door — a change in cell ...

Microscopy

... It helps to reveal protein structures which are recultant to show themselves by usual, more simple, optic microscopy techniques. Cytoskeleton is a good example. Briefly, proteins under study have to be isolated first from cell extracts. Then, specific antibodies are obtained and ...

... 4-skeleton and movement:a single cell cannot have a good skeletal system along with a good locomotor system at the same time(related to cytoskeleton and contractile elements). and so on.... the point is smaller cells = more cells at the same volume = more specialization of function = ...
