Why are riparian zones important?
A riparian zone is the area or interface between land and a river or stream. This zone is
characterized by unique vegetation that grows along the

DNA Replication & Comparison to Transcription
DNA - The Watson - Crick Double Helix
Two helical polynucleotide chains coiled around a common axis
1) 3' to 5' and 5' to 3'
Two chains held together by hydrogen bonds
Purines & pyrimidines
Genes, Gene Control, & Genetic Engineering
What is a gene?
A section of DNA which encodes for a specific RNAs and
subsequently, specific protein products
What are the different forms of genes?
Alleles - alternate forms of genes
Monotreme Reproductive Biology and Behavior
Monotremes are mammals that are oviparous, or egg-laying. There are
only 3 extant species of monotremes: the playtpus and two species of
echidna. Their reproductive systems are highly specialized to facilitate b

Poodles make more poodles. Sheep make more sheep. Replication is a
basic fact of life. All living things make other living things that
are to one degree or another duplicates of themselves. What is the
mechanism behind all this? The ans
