Studying for biology classes is very different from studying for history or English classes. Strategies that worked well in those classes may not work well here. The following are study strategies that are geared toward students in biology classes. You probably won't have time to try all of these strategies, but pick a few that you think may help and try those. The key is to find as many different ways to work with the information that you are given.

It just feels so time consuming. I know that Bio is more time consuming than a lot of other classes. But I guess it just doesn't FEEL productive to me. I feel like I'm spending an irrational amount of time writing things out than I'm going to be spending actually studying the notes, if that makes sense.

The basis for modern genetics began with the work of Gregor Mendel in 1865.[26] This outlined the principles of biological inheritance.[27] However, the significance of his work was not realized until the early 20th century when evolution became a unified theory as the modern synthesis reconciled Darwinian evolution with classical genetics.[28] In the 1940s and early 1950s, a series of experiments by Alfred Hershey and Martha Chase pointed to DNA as the component of chromosomes that held the trait-carrying units that had become known as genes. A focus on new kinds of model organisms such as viruses and bacteria, along with the discovery of the double-helical structure of DNA by James Watson and Francis Crick in 1953, marked the transition to the era of molecular genetics. From the 1950s onwards, biology has been vastly extended in the molecular domain. The genetic code was cracked by Har Gobind Khorana, Robert W. Holley and Marshall Warren Nirenberg after DNA was understood to contain codons. The Human Genome Project was launched in 1990 to map the human genome.[29]

Biology is the study of life and the processes that govern it. While this can get quite complex, gaining a working knowledge of basic concepts will help you to understand the more complicated ideas. The first steps to gaining this understanding are reading the chapter, making notes, and finding ways to apply biology to your life.

Being able to assess weaknessesas well as strengths is an important skill for this course and beyond. Describe what conclusion(s) you draw from the paper as tohow to build and analyze computational biology algorithms and systemsin the future. Most of the assigned papers are have been significantto the computational biology and/or computer science community andhave had some lasting impact on the area.We do not want a book report or a repeat of the paper's abstract. Rather,we want your considered opinions about the key points indicated above. Ofcourse, if you have an insight that doesn't fit the above format,please include it as well.Your reports will be graded on content, not length.
