Real-World Applications

Step 1: The algae stores amounts of energy from the sun, and it is important for scientists to know which genes are expressed when the algae was exposed to high light and how the algae reacts to environments and conditions.

Step 2: We needed to download the RNA-seq data of the algae and to do this we had to download a text file that contained a matrix of many of the specific algae C. zofinginesis samples. Then we need to read the data by using the "import pandas" function as well as the "read.csv" function.

Step 3: We then sliced the data using the "rna_data.iloc[0:10,0:10]" function. This gave us the first 10 rows and columns of the data set. It allowed us to further analyze the data and look more closely. The gene IDs (row headers) all have the form 'Cz' followed by a number, then the letter 'g', then another number. 'Cz' indicates that the gene is from the species Chromochloris zofingiensis, the first number indicates which chromosome the gene is on, and the second number is a randomly assigned ID number.

The sample names (column headers) tell us whether each algae was grown in medium light (ML) or high light (HL), and how many hours the algae was in the light before they collected a sample (eg. 0.5h, 1h, 12h).
