Metric Options: CountsSelecting the 1-year or 3-year option will change the metrics count to percentiles, illustrating how an article or review compares to other articles or reviews within the selected time period in the same journal. Selecting the 1-year option compares the metrics against other articles/reviews that were also published in the same calendar year. Selecting the 3-year option compares the metrics against other articles/reviews that were also published in the same calendar year plus the two years prior.
Example: if you select the 1-year option for an article published in 2019 and a metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019. If you select the 3-year option for the same article published in 2019 and the metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019, 2018 and 2017.

Article Description
Seven transformation-deficient mutants of piliated, competent Neisseria gonorrhoeae was isolated by screening them for their inability to be transformed by chromosomal DNA after chemical mutagenesis. Three distinct classes of mutants were obtained, each of which was piliated, as determined by electron microscopy. One class exhibited abnormal colony morphology and was unable to take up DNA into a DNase-resistant state. A second class was morphologically normal and took up DNA into a DNase-resistant state normally, but was deficient in both chromosomal and plasmid transformation; mutations in these mutants may affect entry of DNA into the cell proper. A third class was similar to the second but was fully competent for plasmid transformation, suggesting that there was a defect in a late stage of chromosomal transformation.
