Additional Biology Flashcards

 


 

Cards

Term
Genomics 
Definition
The study of whole stes of genes and their interactions within a species as well as genome comparison between species 
Term
Bioinformatics 
Definition
The use of computers, software, and mathematical models to process and intergrate biological information from large data set 
Term
Human Genome Project
Definition
An international collaborative effort to process andintergrate biological information from large data sets 
Term
Linkage Map
Definition
A genetic map based on the frequencies of recombination between markers during crossing over of homologous chromosomes 
Term
Physical Map
Definition
Genetic map in which the actual physical distance between genes or other genetic markers are expressed, usually as a number of nase pairs along the DNA 
Term
Metagenomics
Definition

The collection and sequencing of DNA from a group of species, usually an environmental sample of microorganisms 

Somputer software sorts partial sequences and assembles them into genome swquences to identify protein-coding genes and determine the function of products 

Term
Gene annotation 
Definition
Analysis of genomic sequences to identify protein-coding genes and determine the function of their products 
Term
Proteomics 
Definition
Systematic study of the full protein sets coded by genomes 
Term
Psuedogenes
Definition

A DNA segment very similar to a real gene but which does not yield a funcional product

A DNA segment that formerly funcioned as a gene but has become inactivated in a particular species because of mutation 

Term
Repetitive DNA 
Definition

Nucleotie sequences, usually noncoding, that are present in many copies in a eukaryotic genome

Repeated nits may ne short and arranged tandemly or long and dispersed in the genome 

Term
Transposable Elements 
Definition
A segment of DNA that can move within the genome of a cell by means of a DNA or RNA intermediate 
Term
Transposons 
Definition
A transposoble eleent that moves within a genome by means of a DNA intermediate 
Term
Retrotransposons 
Definition
A transposable element that moves within a genome by means of an RNA intermediate transcript of the retrotransponson DNA 
Term

Simple Sequence DNA 

Definition
A DNA sequence that contains many copies of tandemly repeated short sequences 
Term
Short Tandem Repeats (STR) 
Definition

Simple sequence of DNA containing multiple tandemly repeated units of two to five nucleotides 

Variations in STRs act as genetic markers in STR analysis

Used to prepare genetic profiles 

Term
Multigene Families 
Definition
A collection of genes with similar or identical sequences, presumably of common origin 
Term
Evo-devo
Definition

Evolutionary developmental biology

Field of biology that compares developmental processes of different multicellular organisms to understand how thes processes have evolved and how changes can modify existing organismal features or lead to new ones 

Term
Homeobox
Definition
A 180-nucleotide sequence within homeotic genes and some other developmental genes that is widely conserved in animals
