The weeks before Winter Break started, we studied about the meiosis and mitosis, we also learned about enzyme and the reactions that take place in them. There are two reactions that take place in the enzyme, dehydration reaction and hydrolysis. Dehydration reaction is when a new monomer is being add to the chain of polymer, while hydrolysis is when the monomer is being release from the polymer and water is consumed.
In a regular human body, it contains 46 chromosomes total. Through meiosis, the cells only contain 23 chromosomes. When it undergoes meiosis the two cells meet and form a whole set of chromosomes. Mitosis is the process known as asexual, where the daughter cells are identical. Cells that undergo mitosis are identical because an unfertilized egg develops into an embryo using its two sets of maternal chromosomes.
Anyways I hope everyone is enjoying their break so far, we only have one more week left till school start again, so make the best out of this week :) and Happy New Year. Let's make 2011 another great year for all of us :)
