Assignment Description

CHEM 450: Spring 2017:  Python Project. 10 points.

In this project you will develop a python script to calculate characteristics of a nucleotide sequence.

On cougar courses you will find a file names “NucleotideSequence.txt”.  This file is in the familiar FASTA format with the first line starting with a “>” character (and containing the name of the nucleotide sequence) and subsequent lines containing the nucleotide sequence.

Your program should do the following:

1.    Read the FASTA file containing the nucleotide sequence.

2.    Calculate the AT and GC content of the nucleotide sequence.

The GC content of a nucleotide sequence is generally taken as an indicator of molecular stability.  A nucleotide sequence that has higher GC content (than AT) content is said to be more stable due to the presence of 3 hydrogen bonds between G-C pairs (compared to only two hydrogen bonds between A-T pairs).  The GC content determines the melting temperature of double stranded nucleotide sequences, and thus the GC content parameter must be taken into consideration in applications such as PCR, where double stranded DNA is melted to produce single strands.  The GC content (percentage) is defined as:

(number of G nucleotides + number of C nucleotides)*100/sequence length

The AT content is defined in a similar manner.  Note that the GC/AT content can also be reported as a ratio.

3.    Find the complementary strand of the nucleotide sequence.

4.    Determine the coding region of the nucleotide sequence given the following information:

The nucleotide sequence given in the FASTA file has two exons and one intron.  The first exon spans from nucleotide 1 to 63 and the second exon spans from nucleotide 91 to the end of the sequence.

5.    Find the mRNA strand transcribed by the coding region.

6.    Calculate the number of amino acids that would be translated by the mRNA strand (determined in step 5).

7.    Print out the following (formatted in a manner that is easy to understand for the user):

a.    The name of the nucleotide sequence

b.    The number of bases in the nucleotide sequence

c.     The AT content of the nucleotide sequence

d.    The GC content of the nucleotide sequence

e.    The complementary strand of the nucleotide sequence

f.      The coding region of the nucleotide sequence (i.e. the sequence without the intron)

g.    The mRNA strand transcribed by the coding region

h.    The number of amino acids that would be translated using the mRNA strand

Frequently Asked Questions

Is it free to get my assignment evaluated?

Yes. No hidden fees. You pay for the solution only, and all the explanations about how to run it are included in the price. It takes up to 24 hours to get a quote from an expert. In some cases, we can help you faster if an expert is available, but you should always order in advance to avoid the risks. You can place a new order here.

How much does it cost?

The cost depends on many factors: how far away the deadline is, how hard/big the task is, if it is code only or a report, etc. We try to give rough estimates here, but it is just for orientation (in USD):

Regular homework$20 - $150
Advanced homework$100 - $300
Group project or a report$200 - $500
Mid-term or final project$200 - $800
Live exam help$100 - $300
Full thesis$1000 - $3000

How do I pay?

Credit card or PayPal. You don't need to create/have a Payal account in order to pay by a credit card. Paypal offers you "buyer's protection" in case of any issues.

Why do I need to pay in advance?

We have no way to request money after we send you the solution. PayPal works as a middleman, which protects you in case of any disputes, so you should feel safe paying using PayPal.

Do you do essays?

No, unless it is a data analysis essay or report. This is because essays are very personal and it is easy to see when they are written by another person. This is not the case with math and programming.

Why there are no discounts?

It is because we don't want to lie - in such services no discount can be set in advance because we set the price knowing that there is a discount. For example, if we wanted to ask for $100, we could tell that the price is $200 and because you are special, we can do a 50% discount. It is the way all scam websites operate. We set honest prices instead, so there is no need for fake discounts.

Do you do live tutoring?

No, it is simply not how we operate. How often do you meet a great programmer who is also a great speaker? Rarely. It is why we encourage our experts to write down explanations instead of having a live call. It is often enough to get you started - analyzing and running the solutions is a big part of learning.

What happens if I am not satisfied with the solution?

Another expert will review the task, and if your claim is reasonable - we refund the payment and often block the freelancer from our platform. Because we are so harsh with our experts - the ones working with us are very trustworthy to deliver high-quality assignment solutions on time.
