QUESTION 27 Single-nucleotide polymorphisms (SNPs) are __________. polymorphisms affecting a single base of a gene polymorphisms affecting a large portion of the genome, but only a single class of nucleotides (i.e. purines or pyrimidines) polymorphisms that affect only a single trait at a time polymorphisms that reduce an entire gene to a mutant single-nucleotide code

Many gene sequences that are involved in gene regulation contain a conserved sequence. This means that the same DNA sequence can be found in a wide variety of organisms. The sequence contains mostly guanines and cytosines. The gene codes for protein that conserves energy in the cell. The gene produces protein that conserves the structure of the DNA.

Other $p$ ol $A$ mutants of $E$. coli lack the $3^{\prime} \rightarrow 5^{\prime}$ exonuclease activity of DNA polymerase I. Will the rate of DNA synthesis be altered in these mutants? What effect(s) will these polA mutations have on the phenotype of the organism?
1. which of the two types of mutation (gene mutation or structural mutation) would likely persist in the population? Explain. 2. how does a loss or excess in genetic material leads to the expression of an abnormal phenotype?
