.What are the structural and functional differences between DNA and RNA?

Structure:

DNA is a double helix (like a twisted ladder) while RNA is a single helix (like if you cut the twisted ladder in half along the rungs)

Functions:

In humans and most other organisms, DNA stores and transfers genetic information (sort of like a genetic bank). On the other hand, RNA is the one that codes for amino acids and is also the messenger between ribosomes and DNA to make proteins.

abraham lincoln, according to anyone who was connected with agriculture, represented the worst of northern politicians. shortly after lincoln was elected, south carolina seceded from the union. they along with other southern states, retained their anger. in a way, it was their own fault: the democrats were split in the south. some wanted slavery to be extended in other states that were about to join the union and some didn't want it badly enough. lincoln had a solid backing from his party: the republicans were united in not wanting slavery to be expanded.
