DNA microarrays allow scientists to determine the genotype of a chunk of our genome and also measure the how the genes in that chunk are expressed. Using this technique has been essential in isolating genes that predispose people to cancers, and therefore allowing physicians to preemptively identify and monitor at-risk individuals. For instance, the genes BRCA1, BRCA2, and PALB2 have all been identified (using DNA microarrays) and linked to breast cancer. Knowing this allows individuals to seek out testing and take appropriate measures to prevent cancer/monitor the possible onset of cancer, which has proven to be life-saving.
Answer:
Bc milk is full of protein
Explanation:
The answer to this question is Neurotransmitter
Neurotransmitter will create a chemical change inside our body as a response to each situation that we face. This response then will be transmitted toward our body and will determine what we should do next, (this process will be a lot easier to observe during dangerous fight or flight situations)
Answer:
The difference that the scientist would expect to see between body cells and sex cells with respect to cell division is that body cells divide by mitosis for the growth and repair of cells, while sex cells divide by meiosis for sexual reproduction.
Explanation:
The behavior of the different cell types with respect to their division depends on the functions that each type has.
- <u>Somatic cells</u> are those that define the structure and function of the organism, forming tissues by binding together. The process of mitotic division —to obtain from an original cell two identical daughter cells— is important for the growth, development and repair of an individual's tissues.
- <u>Sex cells </u>or gametes have half of the chromosomal charge —they divide by meiosis, a reductive cell division— and are involved in the process of sexual reproduction.
<em> The characteristics described for each cell type explain why the other options are not correct.</em>
