1. Validation was performed for one gene with quantitative RT-PCR on additional samples.

2. If that were true for one gene, then why not all the human genes?

3. The upper fish apparently has one gene for marble and a gene for gold: a very very beautiful Angelfish

4. For example, one gene R1 produces one agglutinogen (antigen) Rh1 which is composed of three "factors": rh', Rh(o), and hr' '.

5. Moreover, the mitochondrial form of the NADP-MDH was used to study the functioning of different alleles at one gene locus during embryonic development.

6. However, the University of Utah considers dimples an "irregular" dominant trait that is probably controlled mostly by one gene but is influenced by other genes.

7. The result of genetic analysis showed that the Apetalous character was controlled by only one gene locus, petalous flower exhibited incomplete dominance over Apetalous flower and that its expression was not affected by cytoplasmic factors

8. The Canton-S, [F.sub.1], and backcross phenotypes were not sufficiently distinct that it could be determined from the Backcrosses whether one gene or more was involved, but no bimodality or increase in variance was evident in the mating speeds of backcross progeny.

9. The present invention relates especially to a DNA fragment that is obtainable from the gene cluster within the genome of $i(Streptomyces) or $i(Actinomyces) that is responsible for staurosporin biosynthesis and that contains at least one gene or a part of a gene that codes for a polypeptide that is involved directly or indirectly in the biosynthesis of staurosporin and to methods of preparing said DNA fragment.
