Answer:
Complete questions include: Answer Bank: Guanine nucleotides, uridine nucleotides, adenine nucleotides, cytosine nucleotides.
Explanation:
Glycine Auxotroph: Guanine nucleotides and adenine nucleotides (Purine nucleotides)
Glutamine auxotroph: Guanine nucleotides and adenine nucleotides (purine nucleotides)
Aspartate auxotroph: Guanine nucleotides, uridine nucleotides, adenine nucleotides, cytosine nucleotides Both purine and pyrimidine nucleotides)
The amino acids glutamine, glycine, and aspartate provide all the nitrogen atoms of purines in a two ring-closure steps to form the purine nucleus. Pyrimidines are synthesized from carbamoyl phosphate and aspartate.
Answer:
The recombination frequency between two genes can not be more than 50 percent due to the independent and random assorting of the genes that are linked generating 50% recombination.
* Genes should be located far enough from one another so that crossover points can be made.
Example: Genes present at the 2 extreme ends of the chromosome.
* There should not be the linkage between the two genes due to linked genes go together. So no recombination happens.
It may be more than 50% if selected parents are heterozygous. But Mendel took homozygous parents. So, the maximum is 50%. There will be no recombinant if the two genes are linked.
The second line of defense is nonspecific resistance that destroys invaders in a generalized way without targeting specific individuals: Phagocytic cells ingest and destroy all microbes that pass into body tissues. For example macrophages are cells derived from monocytes.
