Two important ways by which humans have affected the carbon cycle, especially in recent history, are: 1) the release of carbon dioxide into the atmosphere during the burning of fossil fuels, and 2) the clearing of trees and other plants (deforestation) that absorb carbon dioxide from the atmosphere
In each cell, through a process of gene expression, DNA is transcripted into mRNA which are templates used to create different proteins resulting in different functions in your body.
