DNA replication is semi-conservative, meaning existing strands are used as templates for new strands. The DNA is separated (unwinds) by the enzyme helicase. This enzyme breaks the H bonds between nucleoti...
Line A and line 4y+12x+24 are parallel. This means that they have the same gradient. In y=mx+c the gradient of the line is m. We can rearrange the equation 4y+12x+24 to find m. To begin with subtract 12x...
Quando começou a chover, eu já tinha ido com o cão à rua.This verb tense shows that the action described by the verb happened before another. In this case, I had already walked my dog when it sta...
Here we use the formula for conditional probability:P(C|D)xP(D)=(𝑃(C∩D))= 0.3x0.6=0.18Note: 𝑃(C∩D)=𝑃(D∩C)=0.18Hence P(D|C)=𝑃(D∩C)/P(C) = 0.18/0.2 = 0.9P(C'∩D') = P(C'|D')xP(D')P(C'|D) = 0.7P(D')=0.4P(C')=...
