Learn to allow for skill development in communication, group behavior, decision-making, human resource management and ethics. Personalize your degree when you pair it with a concentration.
M.S. in Bioinformatics
Request Free Information. Bioinformatics is a branch of science, which deals with the overwhelming amount of data, which has become recently available on living organisms as a result of the human genome project and follow-on projects. The need for this branch of science is very real: while it is becoming increasingly simple to obtain experimental information on DNA, RNA, and protein sequences and expression levels, the interpretation of this information is far from straight-forward. This is only partially due to our lack of experimental knowledge at a cellular level. It is also due to a lack of sufficient tools to facilitate comparisons of genes, gene families, enzyme cycles, or whole genomes, to identify functional or structural homologs within and across organisms.
Cell Biology AnimationProvides animations of key biological processes, cell function overview and its anatomy, concept of gene expression as well as principle of evolution.
Chemical BondsBecause of the tendency of atoms to complete their outer energy shells with the stable number of electrons for each shell, atoms with incomplete shells have a tendency to gain electrons, lose electrons or share electrons. Atoms that have gained or lost electrons become ions. Oppositely charged ions form ionic bonds. Atoms that share electrons form covalent bonds. A much weaker, but very important bond in biological systems is the hydrogen bond.
Plant, Animal and Bacteria Cell Models
Living cells are divided into two types - procaryotic and
eucaryotic (sometimes spelled prokaryotic and eukaryotic). This division
is based on internal complexity. The following pages can provide graphic
roadmaps to the organization of both of these cell types. The Periodic TableYou've probably seen this table before it kind of looks like a mess of random letters and numbers, right? Well it's actually one of the most important tools for understanding chemistry!
All new cells come
from previously existing cells. New cells are formed by the process of
cell division which involves replication of DNA and division of the
cells nucleus (karyokinesis) and division of the cytoplasm (cytokinesis).
There are two types of nuclear division: mitosis and meiosis.
Osmosis: the movement of water molecules from an area of
high concentration to an area of low concentration. Cell membranes are
completely permeable to water, therefore, the environment the cell is
exposed to can have a dramatic effect on the cell.
A class of nucleic acids characterized by the presence of
the sugar ribose and the organic base uracil. By contrast, DNA contains
deoxyribose and thymine, respectively. Most RNA molecules, including
messenger RNA and transfer RNA, act as cellular intermediaries; that is,
they convert the genetic information stored in DNA into the proteins
that provide cells with structure and enable them to carry out
metabolism. Nucleic Acids - Building Blocks
Deoxyribonucleic acid (DNA) and ribonucleic acid (RNA)
are both polynucleotides, polymers of molecules called nucleotides.
Nucleotides are composed of three components. A Tutorial on Genes, Genomes, and Bioinformatics
DNA (deoxyribonucleic acid) is usually composed of two
very long helical polymers of nucleotides. The nucleotides are composed
of a sugar (deoxyribose), phosphate, and one of 4 nitrogenous bases,
adenine (A), cytosine (C), guanine (G), or thymine (T). The two polymers
are linked to each other by hydrogen bonds to form a double helix.
Glycolysis occurs in the cytoplasm in the absence of O2. |
