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.
In meiosis, DNA replication is followed by two rounds of cell division to produce four potential daughter cells, each with half the number of chromosomes as the original parent cell. The two meiotic divisions are known as Meiosis I and Meiosis II.
