Blast

1. (Science: biology, suffix) a suffix or terminal formative, used principally in biological terms, and signifying growth or formation. An immature precursor cell of the type indicated by the preceding word, for example; bioblast, epiblast, mesoblast, etc.

2. A violent gust of wind. A forcible stream of air from an orifice, as from a bellows, the mouth, etc. Hence: The continuous blowing to which one charge of ore or metal is subjected in a furnace; as, to melt so many tons of iron at a blast.

3. The terms hot blast and cold blast are employed to designate whether the current is heated or not heated before entering the furnace. A blast furnace is said to be in blast while it is in operation, and out of blast when not in use.

4. (Science: veterinary) a flatulent disease of sheep.

See: blast cell, blastema.

Origin: g. Blastos, germ

How to read this tricky electropherogram?

I am doing an exercise to find the sequence of this electropherogram and confirming the results in NCBI Blast site. I wrote the sequence on the graph to the best of my ability of ~100 bp segments and searched them in Blast... nothing came up. All what I know is that this is ...

Protein sequence

... tga cgg tat acc atc cgc aaa gt" or how can i identify protein from sequence. Thanks a lot for answer becouse I tried couple ways (for example BLAST, uniprot, expasy etc.) and it didn´t work well. It is maybe just becouse I don ´t know how to use them.

peptidyl transferase

Depends what you know. If you have sequence, you can go to BLAST @NCBI http://blast.ncbi.nlm.nih.gov/Blast.cgi?PROGRAM=blastp&PAGE_TYPE=BlastSearch&LINK_LOC=blasthome and search directly against PDB database. Or you can go to PDB's advanced search ...

molecular question.

knowing the organism is crucial but given that its a general question a general answer would be that you would use a nucleotide blast (given that you have the gene sequence).
