DNA together with RNA are the most important molecules in biology. It is the hereditary material in humans and almost all other organisms in our planet. Most DNA is found in the nucleus and some or small portion can be found in the mitochondria.

The main features of the three-dimentional structure of DNA are:
DNA is double-stranded composing of two polynucleotide strands alongside each other which are wound round each other to form a double helix. The two strands are joined together by hydrogen bonds between the bases and these bases form base pairs which is like a rung of a ladder. The base pairs are specific. Base pair A only binds to T (T with A), and C only binds to G (G with C). These are called complementary base pairs. As a wholes, DNA molecules control the production of proteins which characterize each type of organism.

Part A: Research a Forest
Andrews [41]

Answer: I chose rainforest

A rainforest is an area of tall, mostly evergreen trees and a high amount of rainfall. Mean temperatures in tropical rainforest regions are between 20 and 29 °C (68 and 84 °F), and in no month is the mean temperature below 18 °C (64 °F). The main animals are monkeys, Blue Morpho Butterfly, Okapi, Three-Toed Sloth, Jaguar, Capybara, Toucan, and Poison Dart Frog. The main plants are ferns, lichens, mosses, orchids, bromeliads, and of course many types of trees. including the rubber tree. Deforestation is a particular concern in tropical rain forests because these forests are home to much of the world's biodiversity. For example, in the Amazon around 17% of the forest has been lost in the last 50 years, mostly due to forest conversion for cattle ranching. The main cause of deforestation is agriculture (poorly planned infrastructure is emerging as a big threat too) and the main cause of forest degradation is illegal logging.
