酵母基因组数据库的比较研究

A Comparative Study of Yeast GenBank

通过对三个不同版本酵母基因组数据库的比较,给出了近几年酵母基因组中开阅读框架(ORF)和基因的变化情况;发现短的ORF变化不稳定,并给出造成这种不稳定的可能原因是序列的随机性;给出了TY*类ORF和以其它方式命名的ORF(*类ORF)的特点,对所有*类ORF在2001年和2002年的数据库中不复存在提出质疑.

By comparing yeast genomes in three different periods,the variations of ORFs and genes for a recent years are given.The variations of short ORFs are instable. It is possible that the instability comes from the randomness of the DNA sequences. Simultaneously, some obvious characteristics of ORFs named with TY*(TY* ORFs) and ORFs named in other ways (* ORFs) are obtained and the suspicion that all the * ORFs do not exist in yeast genomes in 2001 and 2002 years is presented.
