Biological Databases - Lecture Notes

Flashcards covering key vocabulary and concepts from the lecture.

Biological Databases

Large collections of sequences (DNA, protein) or other data (gene expression, mass spectrometry). Focus is on data representation and querying, not organization.

Proteins

The enzymatic work, signaling to other cells, regulation of gene activity, all of that is is done by proteins, and they are really the machinery that makes the cell work.

DNA

Has all the information on how cells work, all including the instructions for how to make proteins.

RNA

RNA that are active on their own as enzymes and also as signaling molecules.

NCBI

The location for GenBank.

BLAST

A tool for fast database searching that uses database filtering and alignment techniques.

SNPs

Sites in the genome that are polymorphic; where you sample the population, you would get more than one nucleotide; the individuals wouldn't be identical

SNPs

Sites in the genome that are polymorphic; that is where you sample the population, you would get more than one nucleotide. The individuals wouldn't be identical

Gene

Region in DNA with instructions to make a protein.

Transcription

Process of a copy of code being made in the DNA.

Gene

Has many features that make up a gene, different exons and these are regions of the gene that truly encode, and they are they are interspersed with intronic regions that are not used for actually transfer translating. They don't contain the information for making proteins.

Gene

The part of the genome that or the part of the DNA that that has the instructions to make the protein

Regular Expressions

Regular expressions are a way of identifying or giving functions to sequences.
