DNA Clues To Reproductive Behavior
ScienceDaily (AUG22, 2008) — A species of wild yeast goes through a
cycle of sexual reproduction once in every 1,000 asexual generations,
according to new research by Imperial biologists published in the PNAS
journal in April.
The study focused on the wild yeast Saccharomyces paradoxus, which is
able to reproduce both sexually and asexually. The scientific team
used this yeast to examine how sexual and asexual reproduction cause
different types of variations in an organism's DNA sequence. A DNA
sequence is like an organism's 'blueprint' - a complete set of
chemical instructions needed for it to grow and function.
