enkephalin-induced depression of single neurons in brain areas with opiate receptors—antagonism by naloxone
kicyunya [14]

Induced depression of single neurons in brain areas with opiate receptors

  • Enkephalin, applied microiontophoretically, depressed spontaneous and glutamate-induced firing of  one neuron in frontal cortex, caudate nucleus, and periaqueductal gray matter, where enkephalin and high concentrations of opiate receptors are met.
  • More than one depressions were blocked by the specific narcotic antagonist naloxone. The results  are durable with a neurotransmitter or neuromodulator role for this new brain pentapeptide.
  • Opium derivatives have been in medical use for the last  2000 years, and may be   longer than any other class of drugs
  • . The brain regions which was  involved in these actions have been identified in some instances by local microinjection of pmole quantities of opioids.

2. Copy/paste and align the first 5 bases of all introns. Which bases are conserved near intron start ("donor site")?
Delicious77 [7]

Answer:

This question is incomplete

Explanation:

Introns are non-coding regions of a DNA that removed by RNA splicing prior to translation. Alignment is usually done between sequences to see and understand the identity and similarity between two or more sequences.

A region/base is said to be conserved if there is  NO change in any base in that particular region. A multiple sequence alignment (MSA) can be used to align the donor sites of all the introns to see the bases that have not "changed" (and still remained in there exact position) hence conserved across all the donor sites.

NOTE: The donor site of an intron is the 5' end, thus the first five bases in the 5' end are to be used here
