I never seem to know whether to talk about horizontal or vertical gene transmission? For example looking at jan 2013 and the question says.... Using isoniazid to treat diseases caused by other species of bacteria could increase the chance of the bacterium that causes tuberculosis becoming resistant to isoniazid. Use your knowledge of gene transmission to explain how.
Tissues are made up of similair cells.
Organs are made up of different tissues.
And tissues are made out of similar cells that are organised into a structure that serves a specific function
ahhh thank you that did help also when so the sister chromatids get pulled apart, is it in anaphase?
In anaphase sister chromatids are pulled towards opposite poles of the cell.

A chromosome is X shaped, made up of two identical chromatids (a chromatid is replicated to get two indentical chromatids, these are joined in the middle by a centromere to form a chromosome)
If so, does anyone else think it's poop considering it doesn't even cover meiosis, gene transmission and all the nasty stuff?
