Bacteria are so successful because they reproduce asexually meaning that they can make more offsprings at a shorter amount of time. Because they reproduce asexually, if that one bacteria is resistant to a certain other organism, so will its offsprings.
Since biochemical function is determined largely by specific enzymes (proteins), different sets of genes must be turned on and off in the various cell types. This is how cells differentiate.
The event that occurs during meiosis I is that homologous chromosomes separate.
What is meiosis?
Meiosis is a kind of cell division where a diploid cell divides into four haploid cells, which develop to produce gametes.
Meiosis is the process of gamete formation made up of two series of successive divisions namely;
Meiosis I
Meiosis II
In meiosis I, the homologous chromosomes separate into two sister chromatids. Homologous chromosomes are two similar but non-identical chromosomes formed from both parents.
Therefore, the event that occurs during meiosis I is that homologous chromosomes separate.
