Answer:
the order of nucleotides in DNA molecules, hope this helped!

<span>E. Stimulation of T-cell by APC</span>
The initial exposure of the body to an infectious agent e.g. through a vaccine, triggers an immune response most of which rapidly diminishes after the vaccination. However some cells of the immune system called lymphocytes remain with a memory of that pathogen.As a result, if the same pathogen infects a vaccinated person, the memory cells remember and recognize it and rapidly spring into action triggering a much more rapid response specific to that pathogen than the initial exposure, effectively dealing and neutralizing the pathogen.
When levels decrease, the parathyroid releases hormones.
Answer:
True
Explanation:
There are certain limitations associated with the Punnett Squares. They are not useful in case of complex genetic inheritance such as linkage between two genes. In case of linkages it becomes difficult to estimate the distribution of genotypes and phenotypes. For example in case of Nail-patella Syndrome and gene associated with blood group two genes lie on the same chromosome in close vicinity and hence there are high chances of inheritance of these traits in the offspring from the parent thereby causing random distribution of the two traits. This random distribution cannot be captured through punnet square.
The same problem is associated in case where a single gene is determined by multiple genes with graded effects of each gene.
Answer: From top to bottom- T, C, G, A, T, A, T
Explanation:
These are the nitrogenous bases that make up a part of nucleotides in DNA.
There are 4 bases in DNA:
- Adenine
- Guanine
- Thymine
- Cytosine
The bases pair together from A to T and G to C, the way I remember is just reading it as AT GC and it works for me, but you make want to make an acronym if it helps you remember better.
As a result, all you have to do is type in the corresponding base to form the correct base pairs.
