the rungs of the dna ladder are made of
A only pairs with T and C only pairs with G. The rungs of the ladder are made of four different kinds of bases with one base hanging off of the. Dna Replication Ppt Download The bases connect in the middle. . Remember there are four. Your DNA model will be made up of individual rungs like on a ladder and these 2 balls will be the center of the first rung. The bases are held together by hydrogen bonds. Every rung is actually two types of nitrogen bases that pair together to form a complete rung and hold the long strands of nucleotides together. The structure of DNA resembles that of a twisted ladder. The Building DNA Gizmo allows you to construct a DNA molecule and go through the process of DNA replication. An important property of DNA is that it can replicate or make copies of itself. Leave a little space between the balls so theyre not touching. DNAs structure is a double-stranded helix and it resembles t...
