Hello everyone. My
name is Jill Faircloth and, as the title suggests, I graduated from the MSc
last year. My plan is to become a
freelance science writer and Clare has very kindly allowed me a voice on this
blog. I will be blogging from the
Birkbeck Science week next week but first I thought I’d introduce myself.
I read Chemistry as an undergraduate but soon discovered
that aspirations to a glorious research career were incompatible with my lab
skills. I therefore put on a suit and
became a chartered accountant before moving to ICI and working my way up the
finance ladder. That’s where I was when
I had my first child and I would have stayed but an opportunity arose in my
husband’s career and we left for San Francisco for a couple of years. This and the subsequent baby gave me (plenty)
of time to realise that I couldn’t go back to the spreadsheets and I decided to
follow my interest in structural molecular biology.
This took me to where you are now and, since it is March,
and assuming the timetable hasn’t changed too much, you have just navigated
symmetry and are now battling through the fascinating but rather dense protein
lifecycle. Since I know that it can be a
little overwhelming when you’re in the middle of one of the lengthier sections,
I thought I’d give you a quick heads up of what’s in store. Section 9 is on molecular forces and has
quite a different flavour from the rest of PPS.
There’s more physics to contend with but by the end of it the logic
behind protein interactions is much clearer.
After that you’re into the home straight and what I found to be the most
enjoyable part of the course. The last 3
sections deal with how the function of a protein is dictated by its detailed
molecular structure and by the interactions which are promoted or inhibited by
that structure. For me, this is where I
could really get a sense of quite how remarkable the evolution of proteins is. Various protein types are examined and used as
examples of the elegance of mechanisms in which subtle molecular changes can
trigger impressive macro consequences. This
is what the rest of the course has been building up to.
After that you will be out of the comparative comfort of
working through the sections, with some of you performing the delicate
balancing act of simultaneous revision and project work. This is where I can offer you a few top tips
from the previous class. You should
definitely get hold of at least 5 years of past papers. Even if you don’t have time to work through
them all, as you go through you will see that certain topics have a higher
probability of featuring than others.
Also, don’t leave all of your work on the project until after the exam,
particularly if you are new to HTML.
HTML takes a little time to crack, although a speedy way to do it is to
look at the text of previous years’ projects and copy the bits for inserting titles,
tables, pictures and links. Another
reason for getting some foundation research in early is that sometimes a key
review paper may not be available online and, although the Birkbeck library is
extremely helpful, there is a time lag in retrieving hard copies which you may
not be able to accommodate in the time between the exam and the project
submission. Please don’t let these
comments put you off. Producing the
project is hard work but is extremely satisfying as you get the scope to really
engage with a subject in a way that there isn’t often time for during the
coursework. Speaking personally, it was
the experience which inspired me to try my hand at science writing, hopefully
the beginning of a shiny new career.
The other subject which may be on your minds is the choice
of course for the second half of your MSc.
I chose TSMB on the basis that we were told by Prof Nick Keep that it
was the best basis for a PhD and at the time I was labouring under the fond
delusion that I would be able to attract sponsorship to do a part time PhD. I have asked an old PPS colleague who chose
PX for his opinions so that I could give you a brief student’s view of the
choices on offer.
TSMB is Techniques in Structural Molecular Biology. It covers a myriad of techniques that are
employed to decipher the molecular structure of proteins from the DNA
technology employed to code the protein of interest, through the wet lab skills
used to identify, isolate and prepare a sample to the physics of different
methods of structure solution. The
sections consequently vary greatly in density and difficulty but the course has
been thoughtfully structured so that the more demanding sections are
interspersed with the lighter ones. I
found the course very interesting and indispensible for understanding
structural biology literature. I can
definitely see why Nick said that it would be the best basis for a PhD although
I should say that the consensus among the students that I used to chat with
regularly was that it was more challenging than PPS.
PX is Protein Crystallography, which is where a crystal of a
protein is obtained and x-rays are directed through it to produce a diffraction
pattern. This pattern can be interpreted
to give the electron density of each non-hydrogen atom in a molecule and hence
its structure. This is a technique in
which Birkbeck has an extremely strong reputation and consequently is a
tempting course for anyone wishing to specialise. My inside source reported that there was a
good variety between sections and that on balance he found it slightly less
demanding than PPS although I would have to say that his perception probably
speaks to his non-biological background.
There is also the opportunity in this module to handle real data and
solve a structure as a project.
Being that I am over my 1000 word limit, I had better sign
off. I hope that one or two of these
observations may be helpful and wish you all the best of luck with the rest of
the course.
