Pl draw a sketch of your completed dna model. label each material and the part of the dna molecule it represents.

There you go! I hope you like it

DNA - Deoxyribonucleic acid, a macro molecule which has all the hereditary data or information in many living beings.

Function- DNA plays an important role in the production of proteins, along with the metabolism, and reproduction of the cells.

Components- Deoxyribose sugar,A phosphate,A nitrogenous base.( adenine, guanine, thymine and cytosine)

Explanation:

Structure of DNA:

The image is a simplified representation of a short DNA molecule, with deoxyribose sugar molecules in orange, linked to phosphate molecules through a special type of covalent linkage called the phosphodiester bond. Each nitrogenous base is represented by a different color – thymine in purple, adenine in green, cytosine in red and guanine in blue. The bases from each strand form hydrogen bonds with one another, stabilizing the double-stranded structure.

A  reaction  in which  energy  is  released  to the surroundings is called an exothermic  reaction. in this type of  reaction  the enthalpy, or stored  chemical energy, is lower for the products than the reactants. when ammonium nitrate is dissolved in water,  energyis  absorbed  and the water cools.
