Interpretation:
Equation for nickel-58 bombarded with an proton giving alpha particle as product has to be written.
Concept Introduction:
Radioactive nuclides undergo disintegration by emission of radiation. This is a natural transmutation reaction where the nuclide of one element is converted into nuclide of another element. Radioactive decay happens naturally. This can also be done artificially in the laboratory by means of bombardment reaction. Bombardment reaction is the one where the target nuclei is hit by a small fast moving high-energy particle to give a daughter nuclide and a small particle such as proton or neutron. This can be represented in form of a

Given description is an alpha particle bombards with aluminium-27 to give a neutron product. The incomplete equation for this can be written as,
In a nuclear equation the sum of subscript on both sides has to be equal and the sum of superscripts on both sides has to be equal. By looking into the above equation, the sum of superscript in the product side is 1 and the sum of subscript in the product side is 0. This has to be balanced in the reactant side. Sum of superscript in the reactant side is 31. Sum of subscript is 15. There is a short of 30 in the superscript and 15 in the subscript of the product side when comparing with the reactant side. The element with atomic number 15 is phosphorus. Therefore, the missing nuclear symbol is

In a nuclear equation the sum of subscript on both sides has to be equal and the sum of superscripts on both sides has to be equal. By looking into the above equation, the sum of superscript in the product side is 258 and the sum of subscript in the product side is 102. This has to be balanced in the reactant side. Sum of superscript in the reactant side is 246. Sum of subscript is 96. There is a short of 12 in the superscript and 6 in subscript of the reactant side when comparing with the product side. The element with the atomic number 6 is carbon. Therefore, the missing nuclear symbol is

Thank youarrow_forwardMolecular Biology You discover a disease causing mutation (indicated by the arrow) that alters splicing of its mRNA. This mutation (a base substitution in the splicing sequence) eliminates a 3’ splice site resulting in the inclusion of the second intron (I2) in the final mRNA. We are going to pretend that this intron is short having only 15 nucleotides (most introns are much longer so this is just to make things simple) with the following sequence shown below in bold.
