Introduction to Nucleotide Sequencing Analysis with R Nucleotide sequencing is a crucial tool in molecular biology for understanding genetic variations, identifying genes, and analyzing genomic structures. Shotgun genome sequencing involves breaking down an entire genome into smaller fragments, which can then be assembled and analyzed. In this blog post, we will explore how to cut a FASTA file of nucleotides into coding and non-coding regions using R. Understanding the Problem The problem at hand is to separate a shotgun genome sequence into two parts: one containing the coding sequences (CDS) and another containing the non-coding regions.

Step 1: Define the problem We need to add a new column ‘ID’ from another DataFrame ‘df2’ with all values equal to ‘0’ to the existing DataFrame ‘df’. Step 2: Concatenate the DataFrames To accomplish this, we will first concatenate ‘df’ and ‘df2’, ignoring their indexes. This will create a new DataFrame that combines the columns of both DataFrames. Step 3: Fill missing values with ‘0’ After concatenation, there will be missing values in some rows due to the concatenation process.
