Answer:
an electron is exited
Explanation:
as the electrons are released into the system of electron carriers involved with photosystem two, they lose their energy
Answer:
To produce a terminator nucleotide in Sanger DNA sequencing, a(n)<u> oxygen </u>atom is removed from the hydroxyl group on the deoxyribose sugar where it bonds with the adjacent phosphate group
Explanation:
DNA consists of a double helix made up of nucleotides.These nucleotides are arranged in such a way that each nucleotide has a phosphate group , a sugar and a nitrogenous base.
Sanger sequencing is a method of DNA sequencing which is actually based on the selective incorporation of the chain-terminating dideoxynucleotides by DNA polymerase during the DNA replication
The Sanger sequencing has following steps :
1) denature dsDNA using heat.
2) Make multiple copies of a segment.
3) Attach a primer.
4) Add to four polymerase solutions.
5) Grow complementary chains until termination dye.
6) Denature the grown chains.
7) Electrophorese the four solutions.
Mutation are two types somatic and germ cell mutation...as there is mutation in germ cell it will alter the normal behavior and produce variation !
random fertilization also causes variation as different setup of genes meets with another different...so chances of variation increases !
and third crossing over is in meiosis when chiasmata forms....so in this two homologous chromosome attach to each other and on separation ... some part exchange so leads to variation !
Prostatic acid phosphatase was purified from prostatic fluid. Monospecific antisera to the purified acid phosphatase was then produced in rabbits. When antibody was coupled with acid phosphatase, the enzymatic activity was markedly stabilized against pH and temperature degradation. Both acid phosphatase and rabbit anti acid phosphatase were non specifically coupled to Sepharose-4B using cyanogen bromide. Under these circumstances slight stability occurred when antibody was bound to Sepharose, and then acid phosphatase added to the gel antibody complex. When acid phosphatase was complexed to Sepharose, no stabilization occurred.
