Python Programming for Biology: Bioinformatics and Beyond

1

 RNA  stands  for  ribonucleic  acid  and  it  is  present  in  several  fundamentally  important

biochemical situations.

2

 Cells  have  a  specific  kind  of  molecular  particle,  containing  protein  and  RNA  chains,

called the ribosome, which does this job.

3

Strictly 2′-deoxynucleotides if you know your ribose sugar chemistry.

4

By special proteins called helicases.

5

 The  RNAs  that  don’t  act  as  messengers  often  have  a  direct  physical  role  in

biochemistry, just like proteins.

6

This example uses the Protein Data Bank naming system.

7

The versions of a chemical element with different atomic weights, caused by different

numbers of neutrons in the nucleus.

8

A means of separating molecules in a sample according to size, by passing an electric

current through a gelatinous substance in which differently sized chains move at different

speeds.

9

The part that differs between each kind of amino acid.
