Q. As a biologist, what skills do I need to make the transition to bioinformatics?
The fact is that many of the jobs available CURRENTLY involve the design and implementation of programs and systems for the storage, management and analysis of vast amounts of DNA sequence data. Such positions require in-depth programming and relational database skills which very few biologists possess, and so it is largely the computational specialists who are filling these roles. This is not to say the computer-savvy biologist doesn't play an important role. As the bioinformatics field matures there will be a huge demand for outreach to the biological community, as well as the need for individuals with the in-depth biological background necessary to sift through gigabases of genomic sequence in search of novel targets. It will be in these areas that biologists with the necessary computational skills will find their niche.
A. Molecular biology packages (GCG, BLAST etc),
Web and  programming skills including HTML, Perl, JAVA and C++,  
Familiar with a variety of operating systems (especially UNIX),
Relational database skills such as SQL, Sybase or Oracle,
Statistics,
Structural biology and modeling,
Mathematical optimization,
Computer graphics theory and linear algebra.
You will need to be able to readily pick up, use and understand the tools and databases designed by computer programmers, and
To communicate biological science requirements to core computer scientists.
