This week was all about da enzymes. So what are they? Here’s the Bozeman video talking about all the details: http://www.bozemanscience.com/048-enyzmes/ But here are some of the basics: They are chemicals that aren’t consumed in a reaction but speed up the reaction For example, catalase is an enzyme that breaks down hydrogen peroxide into hydrogen and water… Continue reading Enzymes!
Reflecting back on the week, I discovered something: I am still really confused on macromolecules. So, I decided to really focus in on identifying the four different macromolecules, and here are summaries of each. DNA is found in the nucleus There are 4 different types of macromolecules: Nucleic Acids Essentially DNA and RNA Nucleotides are… Continue reading Organic Molecules + Some Basic Review
This week was focused on reviewing chemistry, which proved to be more challenging than I expected! We learned about the pH scale, acids, bases, buffers, and started to look at macromolecules as well. After the chapter review last weekend, I caught up on some key concepts that I previously learned in chemistry. First, pH is… Continue reading Basic Review of Chemistry
The Molecular Origins of Life: 1.D.1 1.D.2 Replication Pros: DNA molecule’s primary function is replication and it carries out a variety of chemical reactions required for metabolism DNA encodes info The structure makes it easy to pass info to descendants In order to replicate, DNA needs proteins RNA is the original life molecule It… Continue reading The Molecular Origins of Life!
I chose to make a Phylogeny tree on the Cytochrome C protein. But what even is Cytochrome C? Cytochrome c is a highly conserved ~12 kDa protein consisting of a single 104 amino acid peptide with a single heme group. Because of its ever-present nature and sequence homology, cytochrome c has been used as a model protein for molecular… Continue reading Phylogeny Trees
This week mainly consisted of learning about genes and alleles. There are two alleles in one gene that is located in a certain position on a certain chromosome. There are two types of alleles: Dominant and recessive. One organism can either be homozygous dominant, heterozygous, or homozygous recessive. Here is a simple picture demonstrating the dominant… Continue reading Genes and Alleles
This week we finished up the anole lab, learned about speciation and later watched a video about desert mice adapting to their environment. Although the anole lab was pretty tedious, in the end I did learn a few new things. It was interesting to learn that even if the same species of anoles lived on… Continue reading Speciation and Natural Selection
