MICR 2340 Lecture Notes - Lecture 5: Chromosome, Nuclease, Cyanoacrylate
Document Summary
Exam 2 lecture 1- dna structure, dna replication. ***lecture 1- llano skips around slides this lecture. Slide 1- transposon is double stranded dna and it is linear and it replicates together with the chromosome because it sits in the chromosomal dna. Transposon breaks and inserts itself, creates mutations when it inserts because it effects the coding sequences. Cells can have many copies of a plasmid. Slide 2- there is only 1 chromosomal dna per cell. Capacity to do conjugation is encoded in plasmids. A-t connects from opposite strands via h- bonds. The backbone of the structure, has negative charge and is exposed to water. Two types of bonds. (look at these in the biology context. ) More energy is needed to make vs. non covalent. (same with breaking the bonds) Weak - non covalent, h-bonds, hydrophobic interactions and ionic bonds (these are established with water in between so they are weak, they are not pure ionic bonds)
