Mutant polymerases have been found which either increase or decrease mutation rates in an organisms containing the mutant enzyme. The mutant that increases the rate is a mutator and the mutant that decreases the rate is an antimutator. The mutator and antimutator activities are usually a result of changes in the ratio of the two enzymatic activities described. This type of tRNA reads this terminator codon and inserts the amino acid tyrosine. If so, describe the circumstances under which translation would be altered and explain how it would be altered.
Gene conversion occurs only when there is heterozygosity for two different alleles of the gene.
Genetics Problem set 4 If DNA having an optical density at 260 nm equal to 1.0 is boiled, OD 260 increases to 1.37. Explain the above observations. C. Assume the DNA is in 0.5M NaCl. Predict the OD 260 changes for a double-stranded deoxynucleotide containing G in one strand and C in the other. Assume that the ionic strength is high.
