Asexual Reproduction Asexual reproduction in the Ascomycetes may be carried on by fission, fragmentation, chlamydospores, or conidia according to the species and to the environmental conditions. Fission & Budding in Yeast: Fission and budding are methods of propagation normally encountered in the yeasts and in a few other Ascomycetes. Spores …

Typification: The nomenclatural type is that constituent element (a spec­imen, or a description or a figure) of a taxon to which the name is permanently at­tached. This need not be the most typical or representative element but is the original material on which the description of the taxon is based. …

Here, the Protista kingdom of Eukarya domain have been shortly introduced at first to get an idea over general characteristics of one of Protista’s members, the marine flora (mainly algae and seaweeds). (To know about domains of life, click here: Three Domain System.) Domain Eukarya Coming from the Greek words …

Fungi are microscopic/macroscopic eukaryotic and heterotrophic organisms exhibiting growth on various natural and synthetic substrates and are capable of continuing their function almost indefinitely.

After much preliminary speculation and a few …

The  first step in sequencing a genome is to divide the individual chromosomes (in eukaryotes) or whole DNA (in prokaryotes) in an ordered manner into smaller and smaller pieces that ultimately can be sequenced. That is, one begins by creating a genomic library of fragmented DNA parts. However, at some …
