How can I clean up this code? It works correctly. However, I feel like I typed this out all the extremely long way and I would love to know how to make this more performant. 

In my next project I would like to not have to type all of these out. I imagine that I am missing some functions or loops. I am still a very new beginner and this is my first project outside of a classroom. 

I wrote this code so I could figure out the amount of molecules within a plasmid and an insert of DNA. I then get the amount of insert DNA I would need to use (in uL) for a ligation with the DNA at different insert ratios and dilutions. Please let me know how I can clean this up.

    print "Please put the amount of BPs: "
    number = int(raw_input())
    solution = (number * 660)
    Avo = (6.022 * (10 ** 23))
    Grams_Avo = ( solution / Avo)
    print "Put in Concentration (ng/ul): "
    conc = float(raw_input())
    multiple = (10 ** -9)
    amount = (conc * multiple)
    total = float(amount / Grams_Avo)
    print "Amount of molecules:  %s" % total
    
    
    print "Amount of ul used by the plasmid: "
    plasmid = float(raw_input())
    particles = float(plasmid * total)
    print "What ratio amount will you use?: "
    ratio = int(raw_input())
    molecules_needed = float(particles * ratio)
    print molecules_needed
    
    
    print "Conc. of your oligo?: "
    oligo = float(raw_input())
    oligo_num = float(oligo * multiple) # amount 
    print "Enter number of G in Oligo: "
    G = int(raw_input())
    print "Enter number of A in Oligo: "
    A = int(raw_input())
    print "Enter number of T in Oligo: "
    T = int(raw_input())
    print "Enter number of C in Oligo: "
    C = int(raw_input())
    sumG = (G * 329)
    sumA = (A * 313)
    sumT = (T * 304)
    sumC = (C * 289)
    daoligo = (sumG + sumA + sumT + sumC) # g/mol
    
    print "Total amount of your insert %s" % daoligo
    
    oligototal = float(oligo_num / (daoligo/Avo)) # molecules for insert
    complete = float(molecules_needed/oligototal) #amount of insert needed from stock ul
    
    print "What dilution will you use?"
    print "1. Stock"
    print "2. 1:10"
    print "3. 1:20"
    print "4. 1:30"
    print "5. 1:50"
    code = float(raw_input())
    if code == 1:
        print complete #stock
    elif code == 2:
        code2 = (oligototal/10)
        complete1 = float(molecules_needed/code2)
        print complete1 #1:10
    elif code == 3:
        code3 (oligototal/20)
        complete2 = float(molecules_needed/code3)
        print complete2 #1:20
    elif code == 4:
        code4 = (oligototal/30)
        complete3 = float(molecules_needed/code4)
        print complete3 #1:30
    elif code == 5:
        code_5 = (oligototal/50)
        complete4 = float(molecules_needed/code_5)
        print complete4 #1:50
