The nucleotide sequence of Saccharomyces cerevisiae chromosome IV

Article Abstract:

The IV chromosome of the yeast Saccharomyces cerevisiae is one of the longest, and the DNA sequence was divided into three parts, with the sequence of 1,531,974 base pairs containing 796 known genes. 225 of the newly identified genes were homologous to previously determined genes, while 253 have unknown functions. Each two kilobases averages around one gene, with a large central domain of lower G+C content, containing all yeast transposon elements and the majority of tRNA genes.

The nucleotide sequence of Saccharomyces cerevisiae chromosome XII

Article Abstract:

Some of the features of saccharomyces cerevisiae chromosome XII are described, including nucleotide composition of 38.48% G+C. 72% of the chromosome sequence contains 534 open reading frames (ORFs), with an average size of 485 codons. 31.8% of the genes were identified previously, and 34 of the newly identified genes have similar characteristics to proteins of know function. It contains 22 tRNA genes, which are widely separated, although there are some clusters.

The nucleotide sequence of Saccharomyces cerevisiae chromosome V

Article Abstract:

The sequence of 569,202 base pairs of Saccharomyces cerevisiae chromosome V is reported, as part of an international collaborative attempt to sequence the total genome of the yeast. Shotgun sequencing and assembly was used, revealing a centromere, 13 tRNAs, four small nuclear RNAs, two telomeres and 271 open reading frames (ORFs). 29% of the ORFs are new, with 30% having potential homologues in public databases.
