Sugars link together by phosphates to create the backbone of the DNA or RNA molecule. Genetic information is carried and stored in the sequence of nucleic acid bases along a chain of DNA or RNA. When cells duplicate inside of the human body, DNA is replicated through RNA in order to give the new cell a new set of DNA.
Hope this helped! :)
The idea of evolution is that the species change over time. The proposed mechanism of evolution is natural selection. Natural selection favors inheritable traits, suitable (adapted) for survival and reproduction. Organisms with such traits will tend to leave more offspring than others, and thus will evolve over time.
Some of the people that influenced Darwin are:
• Lamarck who first proposed that humans evolved from a lower species through adaptations over time
• Malthus, economist who explained that population grows faster than food production could sustain. So, Darwin proposed that only individuals that have favorable adaptations would survive.

Explanation:
Golgi apparatus is an organelle in eukaryotic cells that stores and modifies (might include addition of sugar groups) proteins and lipids for certain functions and prepare them for transport to other parts of the cell.
In the Endoplasmic reticulum, proteins fold into into their correct shape. Some of them are transported to the Golgi apparatus in membrane vesicles. Some proteins need to do their jobs in the Golgi (they are said to be Golgi-resident). They are transported from the golgi appratus to their final destinations through a secretory pathway. It involves sorting proteins into different kinds of transport vesicles, which emanate from the trans Golgi network and deliver their contents to the appropriate cellular locations.
Proteins that are membrane embedded are conveyed to the plasma membrane (integral membrane proteins) by constitutive secretion. Proteins can divert from constitutive secretion pathway and be targeted towards other destinations such as lysosomes (as lysosomal proteins) and regulated secretion from cells (to the cell exterior).
