Amniocentesis essay Amniocentesis referred as amniotic fluid test (AFT)‚ is a medical processes used for pregnancy moreover in the early it used for diagnosis chromosomal and other fetal problems such as; Down syndrome‚ Trisomy 13/18‚ Fragile X‚ Rare-inherited metabolic disorders‚ Neural tube defects by alpha-fetoprotein levels. This technique is used full but more ever there are lots of risk however later on this technique get developing‚ it also can uses to detect problems such as; Infection

Exercise 13 MITOSIS: REPLICATION OF EUKARYOTIC CELLS ANSWERS TO QUESTIONS 1. a. Mitosis and cytokinesis are often referred to collectively as "cellular division." Why are they more accurately called cellular replication? The result of mitosis is production of two cells (replicates) identical to the parent cell. The genetic material is replicated rather than divided. b. Does the cell cycle have a beginning and an end? The organization of our study of cellular events indicates a beginning and

many oogonia as well as primary oocytes become atretic • By the 7th month‚ the majority of oogonia have degenerated except for a few near the surface Note: No oogonia are present at birth • All surviving primary oocytes have entered prophase of meiosis I‚ and most of them are individually surrounded by a single layer of flattened‚ follicular epithelial cells • The primary oocytes enclosed by this layer of cells constitutes a primordial follicle • Primary oocytes begin the first meiotic division

Question 1 1 out of 1 points Which of the following is true about “meiosis”? Select all that apply. Answers: Reproductive cells undergo meiosis Non-germ cells are reproduced Red blood cells undergo meiosis Number of chromosomes reduces by half in phase one Cell divides to produce four daughter cells Response Feedback: Meiosis occurs only in replicating gametes or reproducing cells. In phase one‚ the number of chromosomes is reduced by half but the chromatid pairs remain together. In phase
