The start codon is the first codon of a messenger RNA (mRNA) transcript translated by a ribosome.
Nitrogen base sequence for the start codon is AUG.
Explanation:
plant absorbs water through the root by
the osmosis process
concentration of root is more than water
so. a pressure is developed in the wall of root
by the which water goes up and reaches to the
leaf of the plants
When organisms mate without human interference, it is called natural selection.
The word sponge is more appropriate to use than Underground river since an underground river can loose water while an aquifer cannot loose water, unless it is open-air and above ground. then the aquifer would slowly loose water due to evaporation from the sun.
