1.   Hence, there was an increase in the number of mitochondrial genomes per nuclear genome in the mutant strain.

2.   If a mutant strain appears that eschews recombination, it proves to be especially susceptible to damage by ultraviolet light.

3.   One of the most remarkable observations concerning the mutant strain was the fact that it appeared very little affected by this mutation.

4.   The possible implications of these results on the mutant strain phenotype are discussed.

5.   Early treatment might therefore risk selecting out mutant strains of HIV.

6.   The mutant strain appeared in the south of Shetland, just as the council approved the scheme for another year.

7.   But there is a mutant strain of mice that have hearts on the right.

8.   By mating the unusual mouse with littermates carrying a recessive gene for the same trait, Jackson began developing genetically pure mutant strains.

9.   In mutant strains of arabidopsis that lacked these genes, the researchers discovered, seed pods did not shatter.
