Many genes are arranged in groups of related genes along a chromosome - gene clusters Eukaryotic ribosomal RNA genes: tandem repeats Gene Families Related genes may be organized is several clusters at different locations These are known as gene families e.g. If both show the same pattern, then it is considered to be an indication that the sequence is of high quality and relatively error free. Similarly, when there are gaps in the sequence or insufficient coverage, the finisher will flag the region and send it back to the production sequencing team for more work. This occurs during the finishing step, which is defined as the process of assembling the raw sequence reads into an accurate contiguous genomic sequence. This region is bordered by repeat sequences on each end commonly known as the left border and right border. Mécanismes moléculaires de conservation de l'IG III. The non-coding sequence it carries is removed successfully at the post transcriptional level to form mature mRNA. 4.2. Plant Genomes Both Large and Small. A restriction map is generated from the sequence and then compared with the known fingerprint generated from the clone during the mapping step. In cases where an organism has lost photosynthesis, the plastid genome is typically much reduced in size and coding capacity; occasionally it is lost entirely. PGIR had been assigned the middle portion of chromosome 10 from 29.8 to 41.8 cM. Introduction.
