John, a 19 year old boy, wanted to figure out why he wasn't sleeping well at night. He normally and heads to bed by 11 pm and wa
kes up about 6 am. He works during the day, exercises after work for 1 hour, eats dinner, watches television, checks his phone for messages, and drinks a Pepsi at about 10 pm. What can you infer is keeping John awake at night.
Pepsi is a caffeinated drink that has caffeine in it. Caffeine is a stimulant which means it keeps the body awake and alert. Caffeine works by mimicking adenosine. Adenosine is produced by neuron cells and when it binds to its own receptors (autocrine signaling) it triggers the neurons cells to continue firing. As the adenosine levels fall as the day progresses, the brain is signaled that it is time rest. Adenosine levels are at the lowest when its almost bedtime. However, when Jon takes Pepsi, the caffeine in it bind to the adenosine receptors and make the brain neurons to keep ‘firing’.
The process of cloning effectively involves taking a cell from your body and turning it back into an embryo. The embryo would then either develop into a human being as has been proposed by various scientists around the world and which is currently banned, or it would be turned into a stem cell.
Alanine is obtained as the first amino acid, taking into account that the reaction with the Sanger reagent hydrolyzes N- (2,4-dinitrophenyl) alanine. thus with the fragments of the partial hydrolysis they are organized to create a polypetidic chain
ala-asp-gly-ala
gly-ala-phe
phe-be-wing
be-wing-phe-asp
We obtain that the correct sequence of the peptide is "ala-asp-gly-ala-phe-ser-ala-phe-asp"
Absolutely not! Your hypothesis is your educated guess on how the experiment will go. If in the end of your experiment, you find that your hypothesis was not supported, that does not make you wrong. I hope this helps!
