Document Summary

Lecture 2: chemical foundations ii: membranes cannot be traversed by charged or hydrophilic molecules, ex: calcium cannot cross (charged), sugars cannot cross (too large), but benzene can cross (hydrophobic, small) Lecture 3: chemical foundations iii: amino acids are compose of a central carbon, an amine (nh,+) an acid (coo-), and an r group. It is the r group which determines the aa"s properties. Lecture 5: overview of transcription and mrna formation: initiation begins when the rna polymerase ii binds to a promoter sequence in dna, creating a. When the first phosphodiester linkage between the rntp"s is catalyzed, the system enters elongation. Multiple poly ii molecules can transcribe the same template at the same time. The complex very stable and doesn"t disassociate until it recognizes a stop site. The speed is around 1000 nt/min: rna polymerase ii has a special domain called the carboxy terminal domain, which is long in conformation and has a heptapeptide repeat.

I have an exam coming up but somewhat confused on the Evidence of Evolution. These are the ideas my professor has talked about in class. Fossil Record, Biogeography, Taxonomy, Comparative anatomy (homologous organs/ structures and vestigial structures), Comparative embryology, Molecular biology (biochemistry), and Domestication. (artificial selection). Can you please explain alittle more about these topics. And an example for each would help. Appreciate it

How do you study for biology? Specifically molecular cell bio. It's sad spending so much time studying to end up doing nowhere near as well as you should have. Any specific advice or tips on how to study for biology will be appreciated. Please avoid cliches such as "go to class," "read the book," "take notes," etc.
