How does E. coli determine which nucleotide to "fix" in a base mismatch? The appropriate DNA repair system: A.recognizes fully methylated DNA and replaces the purine. B. recognizes partially methylated DNA and replaces the pyrimdine. C. Recognizes partially methylated DNA and fixes the methylated strand D. Recongnizes partially methylated DNA and fixes the nonmethylated strand E. Makes no distiction between strands, and therefore fixes the wrong base 50% of the time
Gene Interactions
When the expression of a single trait is influenced by two or more different non-allelic genes, it is termed as genetic interaction. According to Mendel's law of inheritance, each gene functions in its own way and does not depend on the function of another gene, i.e., a single gene controls each of seven characteristics considered, but the complex contribution of many different genes determine many traits of an organism.
Gene Expression
Gene expression is a process by which the instructions present in deoxyribonucleic acid (DNA) are converted into useful molecules such as proteins, and functional messenger ribonucleic (mRNA) molecules in the case of non-protein-coding genes.
How does E. coli determine which
A.recognizes fully methylated DNA and replaces the purine.
B. recognizes partially methylated DNA and replaces the pyrimdine.

D. Recongnizes partially methylated DNA and fixes the nonmethylated strand
E. Makes no distiction between strands, and therefore fixes the wrong base 50% of the time
