Nucleotide sequencing: http://www.ncbi.nlm.nih.gov/nuccore/256946799

• Too many nucleotides to list (9986)
• 3 papers to look at
• 84024 rc by 31-AUG-2009
• Sequence has been completed twice by Initial Shotgun Sequence and assembly. Currently there are another 7 groups to recomplete this.

Embryological development is after all the opportunity for a specific Genome to be expressed, regulated and utilized as it will never be again in the adult animal.

Assessment Criteria:

Procedure

   * Project initial assessment by other groups after the Group Project submission date.
         o Written comments will be added to the discussion page. 
   * Group will have opportunity to work on the project in response to comments.
         o Individuals will provide an assessment of their contribution to the final project on their own student page. 
   * Final assessment by course co-ordinator. 20% of final course assessment mark 

Content

Does the group project include the following information?

   * Timeline of Development (how long and key events)
   * Staging (is there a species specific staging and what criteria are used)
   * History of Model Use (what embryological studies have used this model)
   * Genetics (chromosome number, genome sequencing)
   * Current Embryology Research (what embryological studies have used this model) 

Structure

   * Are there visual ways of representing information?
   * Is the content correctly referenced in a reference list?
   * Are there links to related resources/research laboratories? 

Contribution

   * Have all group members contributed?
   * Has the group responded to peer assessment feedback?

RABBIT GENOME:

The National Human Genome Research Institute selected the European rabbit (Oryctolagus cuniculus) for whole genome sequencing to enhance their understanding of the human genome and use it experimentally for an animal model for human disease. (1)

The European rabbit (Oryctolagus cuniculus) has been sequenced twice by The Broad Institute as part of the mammalian genome project. It is now currently undergoing 7 more sequencing projects. Its sequencing is made by the Shotgun Sequence and assembly method. (2) This is when genomic DNA is sheared into small pieces of approximately 2000 base pairs which are then cloned into plasmids and sequenced on both strands. Once the millions of sequenced fragments are read, realigned and reassembled by computer algorithms it will give the overall sequence. (3) (4)

"The whole genome shotgun (WGS) "unfinished Oryctolagus cuniculus database" has serious gaps, yet the information has already proven useful for immunological as well as in silico studies. Deeper 7x coverage started in September 2007. The NCBI Rabbit Genome Resources site has links to searches for genes in the assemblies of the 2x WGS sequence at Ensembl and UCSC useful for designing primers for PCR by predicting mRNA sequences and exon boundaries" (5)

The rabbit genome was sequenced in 2005 by Ensembl and managed to produce: (6)

• 2,076,044,328 base pairs
• 495 Known protein-coding genes
• 11,357 Projected protein-coding genes
• 2,343 RNA genes
• 212,581 Gene exons
• 20,311 Gene transcripts

Chromosomes

Rabbit chromosomes 12, 19 and X were found to be completely homologous to human chromosomes 6, 17 and X, respectively. All other human chromosomes were homologous to two or sometimes three rabbit chromosomes.
