Answer:
The very first DNA isolation was done by a Swiss physician, Friedrich Miescher in 1869. He hoped to solve the fundamental principles of life, to determine the chemical composition of cells.
Answer:
it could not be used because it can attracts the magnets in which compass it self is a form of magnet which can utilize the magnetic properties of the earth to give a reading and Compass housings are often made of either brass, aluminium or plastic.
Explanation:
The characteristic of iron that would make it a bad material for the housing around a compass is that it could not be used because it can attracts the magnets in which compass it self is a form of magnet which can utilize the magnetic properties of the earth to give a reading reason been that Compass housings are often made of either brass, aluminium or plastic
Secondly it would confuse the magnet thereby making it un-useful or useless because the iron can easily become magnetized itself and Iron is a magnetic metal which can cause the needle of a compass to give a false reading thereby messing up the magnet's direction and making it useless.
<span>The importance of the G0 phase is that during cell division when the cell get a signal that there are enough of cells (not more required) or there is a mutation in the cell that need to be fixed before they differentiate fully or the cell during its division gets damage then it is signalled to rest, and it is this phase that cell leave the cycle and quit dividing. It could be temporary resting period (so when cell again required, or damaged got fixed) then the cells will again join the cycle and continue to divide again or it can also be permanent for example neurons, which are resting in G0 phase and never divides again.</span>
