Answer:
C. Electrons are released into the electron transport system.
Explanation:
Photosynthesis has both light dependent processes and light-independent processes. In the light-dependent reactions, photosystem II is the first protein complex. Photosystem II is present in the thylakoid membrane of plants.
<em>When the photons or light energy hits photosystem II, the free electron excites and released into the electron transport system (series of proteins). </em>The electron then passes through electron transport system and the energy from the electron fuels the hydrogen ions to move against their concentration gradient. Once the energy is utilized, the electron is accepted by photosystem I.
Hence, the correct option is C.
Answer:
4 ul Loading Buffer + 19.70 ul dH2O + 0.30 ul DNA Ladder
Load 12 ul on the gel.
Explanation:
DNA Ladder concentration = 1000 ug/ml
1000 ug DNA in 1 ml DNA Ladder solution → 150 ng DNA = 0.15 ug DNA in..... 0.00015 ml = 0.15 ul DNA Ladder solution
6x DNA Loading Buffer → it has to be diluted by an equal volume 6 times (1 ul LB + 1 ul distilled H2O)
An appropriate volume to load on an average agarose gel is 12 ul, so:
2 ul Loading Buffer + 9.85 ul dH2O + 0.15 ul DNA Ladder = 12 ul
But since 0.15 ul is a very small volume and mistakes could be made while measuring it, let's make double:
4 ul Loading Buffer + 19.70 ul dH2O + 0.30 ul DNA Ladder = 24 ul
And load half of that solution (12 ul) on the gel.
The red-green color blindness is a recessive X-linked trait. The females are not affected unless both the X chromosomes have the affected allele. Mostly, the females are the carriers, and the males are affected as they have only one X chromosome. In the given pedigree, the father of Irene have the normal allele, while her mother is a carrier. However, Irene is neither a carrier nor affected. This means that she carries normal alleles on both X chromosomes. Hence, her allele combination is
