DNA is wrapped around proteins called histones, to form nucleosomes. Each nucleosome is a histone octomer composed of (H2A, H2B, H3, and H4) subunits with a 1.65 helical turn of 147 nucleotide bases. Nucleos...

What are the maxima and minima? The maxima of a function f(x) are all the points on the graph of the function which are 'local maximums'. A point where x=a is a local maximum if, when we move a small amount ...

When learning Spanish it’s very easy to get confused over when to use ‘por’ and ‘para’ in a sentence since both mean ‘for’ in English. There are a variety of contexts in which both words can be used, but one...

a is acceleration, v is velocity, s is position vertically: a = - g v = u - gt (by integrating with respect to t and setting initial speed u as constant of integration) s = ut -gt 2 /2 + s 0 (by integrating ...

EXPLANATION: Integration by parts states that ∫uv' dx = uv - ∫u'v dx , where u & v are funcions of x and the notation u' means du/dx. to do integration by parts given an integral ∫f(x) dx, it involves wr...
