Answer:
Ecology is the branch of biology that deals with the relations of organisms to one another and to their physical surroundings.
<span>The bite of an infected ticks. The disease, caused by bacteria of the borrelia type, is transmitted to humans through the bite of infected ticks of the Ixodes genus. Two tick species the black legged tick and the western blacklegged tick are known to transmit the bacterium. Most humans are infected from the bites of immature ticks (nymphs) because adult with Borrelia burgdorferi bacterium are larger and more likely to be discovered.</span>
Answer:
D) with the phosphodiester backbone and with bases via the minor groove
Explanation:
The double helix is a fairly rigid and viscous molecule of immense length and a small diameter. In this molecule a major groove and a minor groove can be observed.
The major groove is deep and wide, the minor groove is shallow and narrow.
DNA-protein interactions are essential processes in cell life (activation or repression of transcription, DNA replication and repair).
Proteins bind to the inner part of the DNA grooves, through specific junctions: hydrogen bonds, and non-specific junctions: van der Waals interactions, and other general electrostatic interactions.
The proteins recognize donors and acceptors of hydrogen bonds, methyl groups (hydrophobic), the latter exclusive of the major groove; There are four possible patterns of recognition in the major groove, and only two in the minor groove (see figures).
Some proteins bind to DNA through the major groove, some others through the minor groove, and some need to bind to both, but the nucleosome form hydrogen bonds via the minor groove with the phophodiester backbone.
Answer:
Gonadotrophin
Explanation:
*GONADOTROPHINS:These are *hormones produced by the anterior lobe of the pituitary gland that regulate the male and female reproductive organ*. The two Gonadotrophins are *Follicle stimulating hormone(FSH) and Luteinising hormone(LH)*. Both are glycoproteins.
*Follicle stimulating hormone stimulates spermatogenesis by stimulating the sertoli cells to complete the development of spermatozoa from spermatids*.
*Luteinising hormone stimulates the synthesis of the hormone "testosterone" by the leydig (interstitial cells) of the testis*. Testosterone is a steroid hormone and is made from cholesterol, It stimulates growth and development of the germinal epithelial cells (spermatogonia) to form sperms,and also works with follicle stimulating hormone to stimulate sertoli cells.
