Watson-Crick model of DNA - 1953
The DNA molecule is a double-stranded helix.
Each base pair has one purine and one pyrimidine, so
the diameter of the double helix is constant.
The twist in DNA is right-handed.
The strands run in opposite directions (anti

From Landers presentation, I learned that Mendel conducted genetic
experiments and made a model based on those. This was not enough to get his
research published, however. To do so, Mendel then proved his model cou

I found the mitosis animation helpful because it took a difficult subject and
showed the movements through the cell. I learned that eukaryotic cells are typically
duplicated every 24 hours; I was unaware of the f
There have always been ideas of evolution, some dating back to Aristotles
ideals. From micro to macroevolution, evolution is everywhere around us and
encompasses all that we see today. I was surprised that the human eye has such

Lander explained linkage as linked genes close together on a chromosome,
which makes them likely to be inherited. Not all genes on a chromosome are linked;
genes that are far apart are likely separate
