The Molecular Origins of Life!

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!

Phylogeny Trees

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

Genes and Alleles

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

Speciation and Natural Selection

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
