Question

Please match the terms on the left with descriptions on the right to review terminology and concepts that have arisen from completion of human and model organism genome sequences. (Not all terms have a match.) gene desert Genes in two different species that arose from the same gene In the species' common ancestor. Skipped protein domain Gones that arose by duplication within a single species, often within the same chromosome paralogous genes gene family A discreto functional unit encoded by an xon: a gene with many exons has many of these A variation in DNA sequence that may or may not have any associated phenotypic result: collectively the source of variability between Individuals syntenic blocks Homologous block of chromosomal sequence between two species' genomes, such as mice and humans. translocation domain architecture The condition in which the same two or more loci are linked in different species orthologous genes The number and order of a protein's domains. Intron A number of closely related genes, usually affecting a single function of process polymorphism conserved Syntony Chromosomal regions containing a megabase or more of DNA with no identifiable genes Reset

Answer 1

Question 5

Genes is two different species that arose from the same gene in the species common ancestor......orthologous gene

Genes that arose by duplication.....paralogous gene

A discrete functional unit encoded by an exon.....protein domain

A variation in the DNA sequence.....polymorphism

Homologous block of chromosomal sequence...syntenic block

The condition in which same two or more loci....conserved synteny

The number and order of protein domain.....domain architecture

A number of closely realted genes.....gene family

Chromsomal region containing more of DNA with no identifiable genes....gene desert
