It is important to use bioinformatics tools to predict sites for posttranslational modifications based on specific protein sequences. However, prediction of such modifications can often be difficult because the short lengths of the sequence motifs associated with certain modifications.
ExPASY contains a number of programs to determine posttranslational modifications based on MS molecular mass data.
In the following question, sentences of a paragraph have been jumbled and labelled as A, B, C, and D. You are required to rearrange the jumbled sentences of the paragraph and mark your response accordingly by selecting the correct option. A. As genome sequencing has become quicker and cheaper, those studies have become bigger and more complex. B. As a result, they comb through genomes in search of variations in DNA sequences and use statistical tools to determine whether those variations contribute to traits and diseases. C. Researchers clearly cannot intentionally introduce mutations into humans; instead, they must use what nature provides. D. Geneticists have long been able to introduce genetic mutations into model organisms such as the fruit fly — first with X-rays or chemicals, and now with more sophisticated gene-editing tools — where humans are concerned, the toolbox is more limited. 
The question below consists of a set of labelled sentences. Out of the four options given, select the most logical order of the sentences to form a coherent paragraph. P. The longer a group of animals remains in one place, the more mutations they accumulate, increasing their genetic diversity.   Q.  Scientists determined the chipmunks’ migration routes by analyzing mutations in their genes.    R. DNA samples from more than 200 chipmunks in Illinois and Wisconsin were used to construct a family tree showing that chipmunks migrated further south only after glaciers receded.    S. Chipmunks recently challenged the scientific dogma that small mammals were forced south during the Ice Age 18,000 years ago.
