Answer:
The correct answer will be option-C.
Explanation:
A karyotype is the visual representation of the chromosome numbers present in a cell of an organism.
The karyotyping is a technique performed to prepare the karyotype of the organism which plays an important role in analyzing the chromosomal abnormalities of the organism.
The analysis of the chromosomal abnormalities helps us study the genetic disorder and diagnose genetic disease. The karyotyping is performed during pregnancy which helps visualize the disease in a family with a history of genetic disorders.
Thus, Option-C is the correct answer.
Answer:
temperature. humidity environment
Explanation:
species will adapt to environment temperature and humidity whether it is a rain forest or snowy mountains
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.
The olfactory cortex (nucus) of the temporal lobe is where the nerve fibers of the olfactory bulb projects directly. This cortex is where you get the smell sensation before determining what the smell actually is. The olfactory cortex is located on the medial aspect of the temporal lobe, particularly in the uncus or the piriform lobe. It is also called the Rhinoencephalon or the nose brain.
