Msamdars Week 2

Electronic Lab Notebook

Purpose

The purpose of this experiment is to learn about models and modeling, as well as the central dogma of molecular biology by utilizing the software Aipotu. We will use this software to learn about the real computational work that systems biologists do and emulate that work with hypothetical organisms as a control.

Methods

Task A

1. Loaded each allele in to Aipotu
2. Created pure-breeding species by continuously self-breeding each initial flower in the Genetics tab.
3. Created hybrids between each pure-breeding flower and a pure-breeding white flower
4. Compared each of these hybrids's DNA seq by using built in compare tool, shown in a screenshot below.
5. Compared each of the amino acid sequences by hand, copying the sequence over from the Molecular Bio screen into the table in the Results section.

Task B

1. Loaded sample by double-clicking on White flower organism in Greenhouse (molecular biology tab if Aipotu pictured on right).
2. Compared sequence using compare tool

Task C

1. Loaded each sample into the Molecular Biology tab.
2. Examined and recorded the color boxes in bottom right of each sample window for each organism.

Results

Task A

*Differences in DNA or protein sequence from that of the white allele are underlined and red.

Task B

Screenshot of differences between white alleles

Given the screenshot on the right, there were no differences in the white alleles.

Task C

The DNA sequences present in each of the starting organisms are given in the table above. The table below describes the allele composition of each of the four starting organisms.

Organism Name	Allele 1	Allele 2
White	White	White
Green-1	Green	Green
Green-2	Blue	Yellow
Red	Red	White

Acknowledgement

This week my partner was John Nimmers-Minor. We worked in and out of class together to better understand the questions. I also asked Mike Armas for assistance with Task D, as he was working on the Biochemistry portion of this assignment. Except for what is noted above, this individual journal entry was completed by me and not copied from another source.
