What kind of data should be shown with standard error bars, and what happens to
standard error as sample size increases? How should you interpret +/- 2 standard
error bars in Biology 171?

Standard Error decreases as sample size increases
The error bars represent "standard error" of the mean or
2+/- standard errors of the mean
What is the genetic material of all living organisms? What are four key characteristics
of it?
Give this one a try later!
DNA
1. Diversity of structure
2. Ability to replicate
3. Mutability
4. Gene expression/Central Dogma
What is the root of a phylogenetic tree? What are the tips of the tree? In what
direction does time run on a phylogenetic tree? What is a node? What does MRCA
stand for?

, most recent common ancestor of all organisms in the tree
tips represent present day (species/organisms living present day)
from root to tip
intersection points that represent the MRCA
MRCA stands for most recent common ancestor
Is the vast majority of life microscopic or macroscopic?

microscopic
What is the difference between B, I, D, and E vs b, i, d, and e?
Give this one a try later!
b=B/N
d=D/N
i=I/N
e=E/N
What is translation? How does the ribosome do translation and what is a ribosome
made of? What is an anticodon? What is the end prodcut of translation?
