121 C at 15 PSI for 15 minutes.
Answer:
You could generate cDNA libraries and compare the transcribed regions of the genome
Hypothesis and Theory are similar because a hypothesis is what you think will happen and theory is what people think does happen.
The two adaptations of endo parasites:
- Endoparasites (a parasite that lives in the internal organs or tissues of its host) produce some compounds of anti-enzymes which defuse or inactivate the host's digestive enzymes.
- Endoparasites maintain their osmotic concentration equivalent to or significantly lower than the host cell for easy absorption of host water and nutrients.
There are three main classes of parasites involve:
- Protozoa include Plasmodium, the single-celled organism. A protozoa inside the host can only replicate, or split.
- Helminths parasites are worms.
- Ectoparasites: These are living on, not in their hosts.
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.
