| 11. | The sexual cycle of one well-studied representative species of Ascomycota is described in greater detail in Neurospora crassa.
|
| 12. | Each of these events is relatively rare, and they do not constitute a regular cycle like the sexual cycle.
|
| 13. | In the absence of this sexual cycle, haploid protocells with a damage in an essential RNA gene would simply die.
|
| 14. | In 2009, " A . fumigatus " was shown to have a heterothallic, fully functional sexual cycle.
|
| 15. | Meiosis leads to sporulation and release of ascospores that may germinate to form haploid cells, thus completing the sexual cycle.
|
| 16. | Akopyants et al . demonstrated that " L . major " has a sexual cycle, including a meiotic process.
|
| 17. | For example, the ubiquitous and industrially important mold, " Aspergillus niger ", has no known sexual cycle.
|
| 18. | A second copy of a single-copy gene is first mate and go through its sexual cycle to activate the RIP machinery.
|
| 19. | Two such haploid gametes, arising from different individual organisms, fuse by the process of fertilization, thus completing the sexual cycle.
|
| 20. | The meiosis stage of the sexual cycle also allows especially effective repair of DNA damages ( see Meiosis and Bernstein et al . ).
