of the thirteenth chromosomes‚ specifically the ATP7B gene which is located in the long arm of each chromosome thirteen and contains the DNA needed to make copper regulating proteins. A point or frame-shift DNA mutation occurs in the ATP7B during meiosis leaving the individual with the wrong nitrogenous base and therefore incorrect instructions to build the proteins that pair up with unneeded copper to excrete it from the body. Studies show frame-shift mutations are a more frequent cause of this disorder

Q1:Why is reproduction essential for organisms? Reproduction is a fundamental feature of all living organisms. It is a biological process through which living organisms produce offspring’s similar to them. Reproduction ensures the continuance of various species on the Earth. In the absence of reproduction‚ the species will not be able to exist for a long time and may soon get extinct. Q2:Which is a better mode of reproduction sexual or asexual? Why? Sexual reproduction is a better mode of reproduction

treating human conditions should be obtained from umbilical cords rather than human embryos. Suggest one reason why. because it is more ethical this way (1) (c) Stem cells divide by mitosis. Gametes are formed by meiosis. Give two differences between mitosis and meiosis. 1 in mitosis the resulting cells of the divsions are clones of the original cell 2 meosis occurs in plants animals and fungi mitosis only occurs in humans.

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
