Answer:
Twins occur.
Explanation:
If the embryo is divided into half by artificial methods such as microsurgical, twins occur in the female body. Both the embryo are identical to each other. twins means that there will be two babies formed at the same time in the body of female. After the separation of embryo, both the embryos are genetically identical to each other and it continue to develop into a new organisms.
Answer: All of the statements are true.
Explanation:
Purines are biologically synthesized as nucleotides and in particular as ribotides, that is, bases attached to ribose 5-phosphate. Adenine and guanine are both derived from the nucleotide inosine monophosphate (IMP), which is the first compound in the pathway to have a completely formed purine ring system.
Purine nucleotides can be synthesized in two distinct pathways. First, purines are synthesized de novo, starting with simple starting materials such as amino acids and bicarbonate. the purine bases are assembled already attached to the ribose ring. Alternatively, purine bases, released by the hydrolytic degradation of nucleic acids and nucleotides, can be salvaged and recycled. Purine salvage pathways are mostly noted for the energy that they save and the remarkable effects of their absence.
All statements are correct because the organization of purine synthetic enzymes involves multifunctional enzymes, reversible enzyme formations, through out the sequence there is maintenance of high local concentration and the ten steps requires only six enzymes.
Can you please post a picture of the diagram?
it is farthest from the sun. As the earth moves around the sun it moves in an eliptical orbit as it gets closer it speeds up and as it moves away it slows down.
