Genome Inventory (as of Feb 21, 2012)

This table reports the number and types of features annotated in the SGD, per chromosome. To get a list of all features of a certain type (e.g. Verified ORF, tRNA, etc.), select that feature type. To access more information on the individual chromosome (e.g. sequence, a listing of all features on that chromosome, etc.), select the Roman numeral for that chromosome.

Summary of Gene Ontology (GO) annotations (as of Feb 21, 2012)

This table displays the current total number of S. cerevisiae gene products that have been annotated to one or more terms in each GO aspect (Process, Function, Component). These counts include GO annotations made for ORFs classified as either "Verified" or "Uncharacterized", transposable element genes, and all RNA gene products. Note that these counts do not include GO annotations made for ORFs classified as "Dubious", or for features of type "Pseudogene", "Not in S288C" or "Not physically mapped". Also note that the number of annotations displayed in the "Total Number of Annotations" column does not include annotations to the three "root" terms representing lack of knowledge at this time, i.e. "molecular function", "biological process", or "cellular component".

Ontology	Details of Annotations
Ontology	Total Number of Annotations	Number of Gene Products Annotated to root terms	Graphical View
Molecular Function	4312	1996	Go to Molecular Function Graph
Biological Process	5104	1204	Go to Biological Process Graph
Cellular Component	5585	723	Go to Cellular Component Graph
All Ontologies	15001	3923

These graphical views representing the GO annotation state of the entire genome are provided using a GO Slim (a high-level subset of Gene Ontology terms that allows grouping of genes into broad categories such as "DNA replication", "protein kinase activity", or "nucleus") tailored to yeast biology. GO Slim terms representing broad categories from a single aspect are listed for each graph, along with the percentage of S. cerevisiae gene products annotated to a specific term that maps up the ontology to the GO Slim term. Note that some gene products may be represented more than once, if they are annotated to one or more GO terms that map to more than one GO Slim term. Only the distribution of "known" Molecular Functions, Biological Processes, and Cellular Components are included in these graphs; annotations to the "root" terms "molecular function," "biological process," or "cellular component," which represent lack of knowledge at this time, are excluded from these graphs.
