<span>First step. It dehydrogenation produces a double bond between the α and β carbon atoms (C-2 and C-3), yielding a trans-Δ2-enoyl-CoA. The symbol Δ2 designates the position of the double bond.</span>
When this occurs the neutrons released by a fission reaction continue striking more nuclei. If the fuel rods in a reactor vessel produce too much heat, this condition may occur.
I think the answer would be yes, the nuclear membrane would be present. It is involved during the process of cytokinesis and is remain unchanged even the process is done. It is a very important part in order to have a healthy cell function.
I would have to say that the percentage since you have to add and then divided would equall 45 percent
In order for offspring to have a dominant mutation, they need at least one copy of the allele from either or both parents. So yes, at least one of the parents must have the mutated gene in order for the offspring to have the mutation.
For your second question, I'm not quite sure what you mean so I will restate two possibilities for what I think you mean:
1. The offspring does not have the mutation if none of the parents have the mutated gene: this is correct.
2. If the mutation is recessive and the child has only one copy of the mutated allele, then the child will not show the mutation. If none of the parents had the mutated gene, then it would not be possible for the child to have the mutated gene or show it.
