Such a group is called a functional group. The âï»¿OH functional group is called a phenol (pronounced fee-nol) group if it is joined to a benzene ring. The same word, phenol, is also used as the name of the compound you made (2.3) consisting of a benzene ring carrying an âï»¿OH group and no other substituent groups.t is a carboxylic acid group and has a whole set of chemical properties that make it different to the âï»¿OH group. To simplify writing this functional group it is often abbreviated to âï»¿COOH or âï»¿CO 2 H. Some people refer to it as a âcooâ (rhymes with blue) group in conversation.
In mitosis, the end product is two cells: the original parent cell and a new, genetically identical daughter cell. Meiosis is more complex and goes through additional phases to create four genetically different haploid cells which then have the potential to combine and form a new, genetically diverse diploid offspring.
Meiosis /maÉªËoÊsÉ¨s/ is a specialized type of cell division which reduces the chromosome number by half. This process occurs in all sexually reproducing single-celled and multi-celled eukaryotes, including animals, plants, and fungi. Errors in meiosis resulting in aneuploidy are the leading known cause of miscarriage and the most frequent genetic cause of developmental disabilities.
