How Do You Make A Human DNA Model Using Clay?
DNA (deoxyribonucleic acid) contains the code for constructing the proteins necessary for life processes. This code is passed on to offspring, making DNA the hereditary material of life. The structure of DNA consists of two helical strands composed of a deoxyribose sugar, phosphate, and one of four bases: adenine, guanine, cytosine, or thymine. The deoxyribose is attached to another deoxyribose by the phosphate group forming the backbone of each strand of DNA. The bases of each strand are hydrogen bonded together in a precise pairing of adenine to thymine and guanine to cytosine. The sequence of these bases in the DNA strand provides the information necessary for the construction of proteins. Loosely wrap two pieces of floral wire along a 2-inch cylindrical object such as a pipe to give the wire the characteristic helical shape of DNA. You should be able to slide the wire off the pipe and not unwrap it. Roll the black modeling clay into 20 1-inch balls to represent the deoxyribose. Rol
