Where A joins to T, and C joins to G 1 of 15 What does the cell membrane do? Controls the movement of substances in and out of the cell 2 of 15 What does the nucleus do? Carries genetic information 3 of 15 What does the cytoplasm do? Where many chemical reactions happen 4 of 15 What does the chromosomes do? Carries genetic information 5 of 15 What are chromosomes made from? DNA 6 of 15 What is a section of DNA called? gene 7 of 15 What is the definition of chromosome? made of a single strand f tightly coiled DNA. Located in the nuclei of cells 8 of 15 What is the definition of gene? Section of a chromosome that codes for making a particular proteins (and therefore controls inherited characteristic) 9 of 15 What is the definition of DNA? molecules that chromosomes are made of, deoxyribonucleic acid 10 of 15 What is the definition of double helix? the more scientific way of referring to the DNA molecular structure looking like a twisted ladder 11 of 15 What is the definition of sugar phosphate backbone? Two strands forming the uprights of the ladder. These strands support the base pairs but do not carry genetic information 12 of 15 What is the definition of complimentary base pairs? Each rung of the DNA ladder is made up of two connected bases. These pairs keep the two strands of a DNA molecules together 13 of 15 What is the definition of organic base? the rungs of the DNA ladder. These are the part of the DNA that carry the genetic information 14 of 15 What is the definition of A, C, G, T? the four types of DNA bases 15 of 15
