The gene GALK1 in human encodes the enzyme galactokinase 1. This enzyme enables the body to process a simple sugar called galactose, which is present in small amounts in many foods. Galactose is primarily part of a larger sugar called lactose, which is found in all dairy products and many baby formulas. # # Supposed you have already the file GALK1.txt which contains the DNA sequence of the gene GALK1 in your current working directory of your computer.

1) Define a function that transcribe the GALK1 gene into its corresponding mRNA, then print out the resulted sequence of the obtained mRNA. Function should be `transcribe(seq,pos)`, which `pos` is the list of (start,end) tuples.

# The coding sequence - CDS (the sequence that codes for the corresponding protein products) of the gene GALK1 is from position 57 to 1235 of the mRNA. You have already the RNA codon table. # # 2) Write a Python function to translate the mRNA of the gene GALK1 into its corresponding amino acid sequence, giving the start and end of the Coding sequence of the mRNA, then print the resulted sequence of the amino acid sequence. # `translate(seq,start,end)`.
