Document Summary
Hlsc 124: lecture 9 notes+ supplemental chapter 8 notes. Tortora, g. , funke, b. , & case, c. (2016). Both sides of the dna strand will align with each other. A-t (two hydrogen bonds) and g-c (three hydrogen bonds) Repeating sequence of 2-5 base pairs that make up a noncoding: dna is anti-parallel region. One dna strand is upside down relative to the other strand. Sugar (deoxyribose) is turned upside down: as a result, whatever is attached to the sugar is also upside down. Bases are as a result very close together and are easily able to bond quickly: form a very stable structure. Carbon 5 contains phosphate group: points up on one side and down on the other. As a result, the strands run in different directions. 5(cid:859) 3(cid:859) (cid:894)right dire(cid:272)tio(cid:374), (cid:272)alled the leadi(cid:374)g stra(cid:374)d(cid:895) a(cid:374)d 3(cid:859) 5(cid:859) (opposite direction, called the lagging strand) The creation of one new strand and is coupled with an old strand.
