The Cell Theory 1. Organisms consist of one or more cells 2. Cells are the smallest living things 3. Cells are formed by division of previous cells The Gene Theory DNA sequences may be altered by mutation or by crossing over and segregation during meiosis Brainpower Read More T...

Accuracy a measure of how close a result matches a correct or standard value Precision a measure of variability. For example, three darts placed close together on a dartboard indicate high precision, but if this cluster of darts is far from the bullseye it would also indicate low accuracy ...

What is the difference between the coding and non-coding region? Coding region: comprised of genes that encode proteins (instructions that determine traits) and makes up 1-2% of human DNA. • Noncoding region: makes up 98-99% of human DNA, contains STRs and is responsible for regulatory functions ...

In the DNA isolation procedure, why did we add chelex-resin to the tube? The chelex-resin absorbs ions that inhibit the function of Taq Polymerase. Write down the components of the master mix that were use in the PCR amplification of STRs. - Buffer - Loading Dye - Deoxynucleotides - 3 pa...

What is a theory? A unifying explanation that has withstood many attempts to falsify it through scientific investigation over a prolonged period of time What are the 4 unifying theories in biology? - The Cell Theory - The Gene Theory - The Theory of Heredity - The Theory of Evolution ...

EUKARYOTIC CELL Cell containing a nucleus and membrane-enclosed organelles PROKARYOTIC CELL Cell that lacks a nucleus or other membrane-enclosed organelles Brainpower Read More Previous Play Next Rewind 10 seconds Move forward 10 seconds Unmute 0:00 / 0:00 Full screen L...

Domain Archaea Prokaryotic, single-celled organisms; have cell walls; reproduce using binary fission (duplication); RNA sequence is most similar to Eukarya; live in extreme environments and therefore do not infect humans; oldest life forms; include methanogens, extreme thermophiles, and extreme hal...

describe the basic functions all life forms must accomplish -response to environmental stimuli & maintain homeostasis -uptake and processing of nutrients/energy -regulation -growth and reproduction compare and contrast eukaryotic and prokaryotic cell types Prokaryotes: -circular chromos...
