A method is presented for the purification of mRNAs and the identification of structural gene sequences in recombinant DNA molecules. RNA is hybridized to double-stranded linear DNA such that R-loops are formed between most DNAs and their complementary RNA sequences. These R-loops are purified from unhybridized RNAs by gel filtration chromatography in the presence of a high concentration of salt. The complementary RNAs are released from the R-loops by heating, and are assayed by gel electrophoresis or cell free translation to determine their purity and to identify the proteins for which they code. We have demonstrated that recombinant DNAs containing sequences for abundant or moderately abundant mRNAs of Saccharomyces cerevisiae can be identified by this means.
This research output has an Altmetric Attention Score of 3. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 29 January 2021.
All research outputs
#7,481,847
of 22,870,727 outputs
Outputs from Nucleic Acids Research
#12,455
of 26,355 outputs
Outputs of similar age
#4,091
of 26,122 outputs
Outputs of similar age from Nucleic Acids Research
#24
of 84 outputs
Altmetric has tracked 22,870,727 research outputs across all sources so far. This one is in the 44th percentile – i.e., 44% of other outputs scored the same or lower than it.
So far Altmetric has tracked 26,355 research outputs from this source. They typically receive a little more attention than average, with a mean Attention Score of 6.6. This one is in the 24th percentile – i.e., 24% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 26,122 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 30th percentile – i.e., 30% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 84 others from the same source and published within six weeks on either side of this one. This one is in the 2nd percentile – i.e., 2% of its contemporaries scored the same or lower than it.
