Georgia O’Keeffe.  The Chestnut Grey, 1924

By GINA KOLATA The New York Times, APRIL 23, 2015

The experiment with human embryos was dreaded, yet widely anticipated. Scientists somewhere, researchers said, were trying to edit genes with a technique that would permanently alter the DNA of every cell so any changes would be passed on from generation to generation.

GENCODE: The reference human genome annotation for The ENCODE Project

Abstract

The GENCODE Consortium aims to identify all gene features in the human genome using a combination of computational analysis, manual annotation, and experimental validation. Since the first public release of this annotation data set, few new protein-coding loci have been added, yet the number of alternative splicing transcripts annotated has steadily increased. The GENCODE 7 release contains 20,687 protein-coding and 9640 long noncoding RNA loci and has 33,977 coding transcripts not represented in UCSC genes and RefSeq. It also has the most comprehensive annotation of long noncoding RNA (lncRNA) loci publicly available with the predominant transcript form consisting of two exons. We have examined the completeness of the transcript annotation and found that 35% of transcriptional start sites are supported by CAGE clusters and 62% of protein-coding genes have annotated polyA sites. Over one-third of GENCODE protein-coding genes are supported by peptide hits derived from mass spectrometry spectra submitted to Peptide Atlas. New models derived from the Illumina Body Map 2.0 RNA-seq data identify 3689 new loci not currently in GENCODE, of which 3127 consist of two exon models indicating that they are possibly unannotated long noncoding loci. GENCODE 7 is publicly available from gencodegenes.org and via the Ensembl and UCSC Genome Browsers.

23-DNA-information

Ατέλειωτος ο κόσμος του DNA, τα γονίδια απέραντο πεδίο της πιο ελκυστικής στις ημέρες μας έρευνας, διαρκείς ελπίδες και απίθανα όνειρα των επιστημόνων για ένα νέο “βιολογικό παράδειγμα”.

Ένα οδοιπορικό στον επιστημονικό και … κοινωνικό κόσμο του DNA. Περιλαμβάνει αποδελτιώσεις (προφανώς προσωπικής επιλογής) και αρθρογραφία, ελληνική και αγγλόφωνη.
