Funding Alert: Contact Congress for Emergency Funding for ZikaPlease contact Congress to urge the immediate passage of a bipartisan emergency supplemental bill for Zika.
Many students studying DNA structure do not understand or cannot fully visualize the concepts of complementarity, antiparallel, and the organization of the 5’ and 3’ ends of a nucleotide strand. Here, a method that works very well to get students actively involved in the process of describing a DNA molecule is described. Students themselves are used as the nucleotides in this activity.
By completing this activity, the student will be able to:
Necessary Student Background
Students should have prior knowledge about DNA’s role as the genetic material and about the double-helical nature of the DNA molecule. General knowledge about the process of DNA replication, transcription, and translation is also helpful. Additionally, students should:
· be familiar with the structure of nucleotides in terms of their sugar, phosphates, and base.
· be able to identify the sugar, phosphates, and base of a nucleotide.
· understand why the carbons of organic molecules are numbered.
· be familiar with Chargaff’s rules.
· be able to explain hydrogen bonding and base pairing.
