Résumé

Retroelements, constituting about 50% of the human genome, both contribute to its evolution and threaten its integrity and are thus silenced during development. Jacobs et al. (2014) identify sequence-specific KRAB-ZNF proteins that repress subsets of L1 and SVA retrotransposons in humans, highlighting the evolutionary interplay between retroelements and their hosts.

The human genome is a complete set of nucleic acid sequences for humans, encoded as DNA within the 23 chromosome pairs in cell nuclei and in a small DNA molecule found within individual mitochondria. These are usually treated separately as the nuclear genome and the mitochondrial genome. Human genomes include both protein-coding DNA sequences and various types of DNA that does not encode proteins. The latter is a diverse category that includes DNA coding for non-translated RNA, such as that for ribosomal RNA, transfer RNA, ribozymes, small nuclear RNAs, and several types of regulatory RNAs.

Projet Génome humain

vignette|Le génome humain est constitué de l'ensemble de l'information portée par nos 23 paires de chromosomes. Le (PGH, ou HGP pour l'anglais Human Genome Project) est un programme lancé fin 1988 dont la mission était d'établir le séquençage complet de l'ADN du génome humain. Son achèvement a été annoncé le . Le nouveau projet lancé dans la foulée en , ENCODE (Encyclopedia of DNA Elements), donne des résultats importants sur l'ADN non codant humain.

Reference genome

A reference genome (also known as a reference assembly) is a digital nucleic acid sequence database, assembled by scientists as a representative example of the set of genes in one idealized individual organism of a species. As they are assembled from the sequencing of DNA from a number of individual donors, reference genomes do not accurately represent the set of genes of any single individual organism. Instead a reference provides a haploid mosaic of different DNA sequences from each donor.

Ancestral genome reconstruction enhances transposable element annotation by identifying degenerate integrants

Didier Trono, Evaristo Jose Planet Letschert, Wayo Matsushima

Growing evidence indicates that transposable elements (TEs) play important roles in evolution by providing genomes with coding and non-coding sequences. Identification of TE-derived functional elements, however, has relied on TE annotations in individual s ...

Single-mitosis dissection of acute and chronic DNA mutagenesis and repair

Christina Ernst

How chronic mutational processes and punctuated bursts of DNA damage drive evolution of the cancer genome is poorly understood. Here, we demonstrate a strategy to disentangle and quantify distinct mechanisms underlying genome evolution in single cells, dur ...

Genome sequences of Vibrio cholerae strains isolated in the DRC between 2009 and 2012

Melanie Blokesch, Sandrine Stutzmann, Alexandre Lemopoulos, Natalia Carolina Drebes Dorr

Vibrio cholerae has caused seven cholera pandemics in the past two centuries. The seventh and ongoing pandemic has been particularly severe on the African continent. Here, we report long read-based genome sequences of six V. cholerae strains isolated in th ...
