The DNA microarray is a technology that is used to identify whether a specific person's DNA has mutations in genes like BRCA1 and BRCA2 which cause cancer.

  • Therefore, a microarray assesses the quantity of mRNA transcripts in a sample, A genome-wide perspective of gene expression in cancer can be obtained since thousands of gene fragments can be found on an array.
  • The idea behind microarrays is that sequences that are complimentary to one another will bind to one another.
  • Restrictions endonucleases fragment the unidentified DNA molecules, which are then labeled with fluorescent dyes.
  • These are then given a chance to interact with DNA chip probes.

What gland is essential to the menstrual and ovarian cycles
TiliK225 [7]
C. Pituitary gland.

The pituitary gland is responsible for the release of follicle-stimulating hormone and leutinizing hormone. Follicle-stimulating is important in the follicular phase of the menstrual cycle, as it stimulates the development of ovarian follicles. Leutinizing hormone is important in the initiation of ovulation and in the stimulation of the corpus luteum to produce progesterone.

Why does Interstate 95 seem to follow the fall line?
Ede4ka [16]

Interstate 95 seem to follow the fall line because it was designed to go around rapids and waterfalls

Explanation:

The extreme side of the coastal plain of Virginia that has a chain of rapids and falls as its mark and which has rivers flowing around it is remarkably known as – Fall line. This observation was performed by John Smith first. This line has remarkable impact on Virginian geology.

The line of falls around it prevented the way of ships and led to the formations of some cities of Virginia. The connecting line of major cities of east coast, the Interstate 95 runs parallel to the fall line. This actually seems that it follows the fall line.
