Dna Replication 3d Model. Leading and lagging strands dna polymerase rna primers primase dna ligase helicase topoisomerase single strand binding proteins nucleotide bonding phosphate backbone helixical strucutre of dna. To make a dna model using supplies you probably already have take 4 pipe cleaners and cut 2 of them into 2 inch strips.
3d model demonstrating the bidirectional nature of dna replication and illustrating structures such as. Next choose colors to represent cytosine guanine thymine and adenine. It shows how both strands of the dna helix are unzipped and copied to produce two identical dna mole.
Transcript this is a model of dna a double strand of dna and when it s replicated it is replicated semi conservatively.
This 3d animation shows you how dna is copied in a cell. Your finished model should resemble a ladder. Just attach the bases like steps of a ladder between the two strands twist them and your dna model is ready. 7 to show replication of your model separate the left side from the right side on your desk leaving a space of about 15 to 20 cm.
