In the story and according to Scrooge, the place were poor people work to get their food is the workhouse. It is also the place where Scrooge things poor people must spend their Christmas. Aside from this, he also said that the prison is also a place for poor people during Christmas.
Answer:
The radiant energy of the sun is used by chlorophyll as an energy source to excite photosystems I and II, which are located in the membrane of the thylakoid.
Explanation:
When the light energy is converted into chemistry inside the photosystem, electrons are released and travel from photosystem II to photosystem I, through a protein complex; plastoquinone, cytochrome B, and plastocyanin.
When light hits, enzymes with REDOX power are activated while in photosystem I, one of the electrons converts NADP to NADPH, capturing protons from the stroma. Finally the NADPH and the ATP generated by the ATP synthetase of the thylakoid membrane, are products of the light stage of photosynthesis
The type of ion channels responsible for the depolarization phase of an action potential are Na+ (sodium)
channels. Sodium ions flow inward through the sodium channels and cause an
increase in the concentration of positively charged ions in the cell; this in
turn, leads to depolarization.
Hi,
Recombinant DNA technology is the process in which a target gene of interest is replicated by inserting it into a vector and creating a recombinant DNA. This recombinant DNA is then returned into an expression system where it is replicated several times to give rise to multiple copies of our desired gene or that gene product.
One of the very important role for the execution of this technology is performed by Restriction endonuclease enzymes. These are the enzymes that have ability to cut the DNA fragment at specific sequence into fragments of different lengths called restriction fragments.
- They play a very important role in recombinant DNA technology:
- They can map the location of specific restriction sites where the target sequence is identified and cleaved.
- They cut down the DNA at specific sites called restriction sites. The host DNA in which foreign gene or target gene is inserted is also cut with the same restriction enzymes. So in the recombinant DNA technology, restriction enzymes act like a molecular scissor which identify and cut certain DNA sequences as per or requirement.
- The target sequence can be cut from multiple places by restriction enzymes since our target sequence can be present multiple times in the DNA of organism.
- When restriction enzymes cut the DNA, they leave sticky or blunt ends at that site in such a way that these ends are able to bind with the complementary bases of vector DNA when introduced.
- Then another enzyme DNA ligase seals the ends of target DNA and vector DNA making a whole recombinant DNA that is ready to be cloned and progress further steps of recombinant DNA technology.
