Sense strand is coding strand while antisense strand is non-coding. Sense strand is same as mRNA but thymine in DNA is replaced by uracil in RNA. On the other hand, antisense strand acts as template for RNA synthesis. Sense strand has codons and antisense strand has non-codons.
Technological factors have played signifiÂ­cant role not only in overcoming environmental constraints but introducing new changes and develÂ­opments in agriculture. These factors include irrigaÂ­tion, fertilisers, high yielding variety of seeds, insecÂ­ticides/pesticides, farm machineries and financial institutions, etc.
The positive effects of agriculture. The results of the Neolithic Revolution were striking. On the positive side, a farmer was able to grow more food than he needed to feed his family, so for the first time in human history we saw specialization. Agricultural societies were able to support leaders, artists, craftsmen, priests, scribes, and soldiers, none of whom had to worry much about where their food came from.
