The TYR, TRP2, and TRP1 genes are located next to each other on a single chromosome and are organized into an operon is most likely to be accurate.
The option a is correct.
Explanation:
The genes for the Tyrosinase, TRP2 and TRP1 are located on the same chromosome and are operons. These are operons because they are controlled by same transcription factors on mRNA.
Tyrosinase enzyme is important for the synthesis of melanin, eye pigments and hair colour. The synthesis of all these is completed in three distinct reactions catalysed by TRP1, TRP2 and Tyr genes. These work as operon and the protein product is almost 40% similar of the three genes.
The amount of melanin production depends on tyrosinase enzyme activity of all the three genes.
The genetic regulation is done by operons.
<h2>Henrietta Discovery </h2>
Henrietta Swan Leavitt discovered cepheids in 1908 during the investigation of different stars in the clouds. She published it by working more on it in 1912 and died in December 1921. This discovery was so important in the society in which she lived because the cosmologist of America was known for this discovery of Cepheids which is a relationship between period, luminosity and quivering stars which changes in light.
Answer:
Explanation:
Hernias are cuts in the muscles that makes the body bulge out. It can occur in the stomach region where intestine lies leading to its bulging out. Hernias has been traced back to early years and until recent it still exist.
Hernia are mostly common in man with little traces in woman. Some hernia are due to some congenital defect and could be found in new born. It is characterized by heart burn,cough, pressure on the affected part.
Hernia are said to be genetic, and this has lead to the continuity in human nature and not its reduction. Hernia have claim some life's especially the severe ones if not properly treated, some people have died in the theater room while be operate upon while some people are in sever pain of the disease. Hernia as at 2015 is present in 18.5million people and has caused death of about 59,800.
Rhizome
Rhizomes are a type of stem that grows horizontally underground. They are capable of propagating vegetatively or asexually. Rhizomes store starches and proteins that allow them to grow all-year-round underground. Examples of which would be ginger, turmeric and lotus.
