Tubulin is a structural protein that comes in three different types, alpha, beta and gamma. Of these three different proteins, alpha tubulin and beta tubulin are almost always found bonded together. These bonded tubulin form heterodimers, these are the basic unit of microtubules in eukaryotic cells. “Microtubules form a framework for structures such as the… Continue reading Blast Lab Protein: Tubulin
Inside of every person’s, and animal cells there is Melanin. Melanin is produced by cells called melanocytes in the skin. It’s responsible for all the different color variations in not only skin but hair and eye as well. It is a pigment that comes in two different shades. Eumelanin is dark brown and black in… Continue reading Why We Have Different Skin Colors
Alfred Russel Wallace was this amature scientist from Wales of all places, who is probably one of the chillest people is science history. Born in 1823 to some not so wealthy parents, he had very limited education. In fact he only went to school until the age of 14, before his father went broke and… Continue reading Alfred Russel Wallace
Viruses are really small infection causing particles. They used to be thought of as bacteria before scientists realized that they were much much smaller. The structure of a virus is just a small piece of deoxyribose nucleic acid or ribonucleic acid. The sizes of the genomes vary from only seven nucleotides long, like Ebola, to… Continue reading Are Viruses Living?
In the activity we did we were given a DNA sequence and had to figure out what protein it was used to create. The protein that my DNA sequence ended up coding for is called BRCA. I figured this out by taking my DNA sequence and transcribing it into the complementary mRNA. Once I did that… Continue reading Blast Activity
Symbiosis is an equally beneficial partnership between two organisms. An example would be the bacteria in our stomach that help break our food down. Eukaryotic cells are cells that have organelles and a nucleus. These include animal and plant cells. Single celled organisms like bacteria are classified as prokaryotic cells, cells without a nucleus,… Continue reading Explaining Symbiogenesis (The Endosymbiotic Theory)
The process of creating high fructose corn syrup was established during the 1950s. It wasn’t till the 70s that HFCS was being manufactured with the quantities of today’s foods. The reason for the increase of production is that it was cheaper to make because of the tariffs on sugar. Corn is milled down into cornstarch,… Continue reading High Fructose Corn Syrup vs. Sucrose
