What must be done to ensure dna made is a laboratory is radioactive

Incorporating radioactive nucleotide must be done to ensure DNA made is a laboratory is radioactive

Explanation:

Radioactive nucleotide are generally used in the detection of some specific nucleic acid series. These are the typically incorporated inside the DNA and RNA series for detection as well as analysis. These nucleotide involves radioactive phosphates, digoxygenin, biotin, fluorophores and enzymes. It was first used in 1935 by George de Hevesy. P32 and S35 labelled as the nucleic probes and now the phosphates is being in large use. Hydrogen can also be used in-situ hybridisation which gives greater resolution and less sensitive in long exposure.

c) 50% there are four chromosomes. after crossing over, 2 of the four have been changed. that means any gamete has a 2 in 4 chance or 50% chance of receiving the mutated chromosome.

enzyme active site and substrate specificity

enzymes bind with chemical reactants called substrates. there may be one or more substrates for each type of enzyme, depending on the particular chemical reaction. in some reactions, a single-reactant substrate is broken down into multiple products
