However, in 1970 when the scientists Howard Temin and David Baltimore both independently discovered the enzyme responsible for reverse transcription, named reverse transcriptase, the possibility that genetic information could be passed on in this manner was finally accepted.

However, Stephen Oppenheimer and Bryan Sykes argue that there was no population displacement, as the Anglo-Saxons had relatively little genetic impact on England.

However, multiple and varied genetic effects each of small size, interacting with the environment, makes this difficult.

However, twin and adoption studies suggest that genetic factors interact with environmental factors for stuttering to occur, and many stutterers have no family history of the disorder.

However, the most useful traits for genetic analysis are present in different forms in different individuals.

However, typological similarities such as these do not constitute evidence of genetic relationship on their own, as they may be the result of regional influence or coincidence.

However, the unperturbed Dr. Lamar, who for years has been asking Vincent during physical exams if he ever told Vincent the story of his own son, once again asks and this time goes on to tell it: His son admires Vincent and wants to be an astronaut despite a genetic defect that would rule him out.

However, Af adsorbs water from the atmosphere and this may account for the low chromium analysis and high total weight loss.

However, the statistical offices of both governments were assigned responsibility for the planning and analysis of these statistics.

However, when applied to data from non-randomized experiments or observational studies, model-based analysis lacks the warrant of randomization.

However, Curie also worked with unshielded X-ray tubes during World War I, and analysis of her skeleton during a reburial showed a relatively low level of radioisotope burden.

However, its primary use since at least the late 1980s has been to describe the application of computer science and information sciences to the analysis of biological data, particularly in those areas of genomics involving large-scale DNA sequencing.

However, a different notion of compactness altogether had also slowly emerged at the end of the 19th century from the study of the continuum, which was seen as fundamental for the rigorous formulation of analysis.

However, alternative analysis suggests that the nominal particles do not function as clitics, but as phrasal affixes.

However, the best modern analysis of the sources of the creed ( by A. de Halleux, in Revue Theologique de Louvain 7, 1976 ) and a reading of the acts, or proceedings, of the council ( recently translated into English ) show that the bishops considered Cyril the great authority and that even the language of ' two natures ' derives from him.

However, recent investigations of languages with very complex click systems such as Nǁng have revealed that the supposed velar – uvular contrast is actually a contrast of a simple clicks versus click – plosive airstream contours ( or consonant clusters, depending on analysis ).

However, recent analysis of the Archaic elements of the treasury suggest that its founding preceded this.

However, statistical analysis shows that this can only account for 50 % of the observed pattern, and other evidence ( such as fungal spikes ) provides reassurance that most widely accepted extinction events are indeed real.

However the general concept of linear filtering is broader, also used in statistics, data analysis, and mechanical engineering among other fields and technologies.

However, in 2009, this hypothesis was disproved when DNA analysis identified the Falkland Island wolf's closest living relative as the Maned Wolf ( Chrysocyon brachyurus )— an unusually long-legged, fox-like South American canid, from which it separated about 6. 7 million years ago.

LB is relatively new and is ineffective in resolving fragments larger than 5 kbp ; However, with its low conductivity, a much higher voltage could be used ( up to 35 V / cm ), which means a shorter analysis time for routine electrophoresis.

However, extraction, amplification and analysis of these nucleic acids from formalin-fixed, paraffin-embedded tissues is possible using appropriate protocols.

However, in the case of Griggs v. Duke Power Co. in 1971, for the purpose of minimizing employment practices that disparately impacted racial minorities, the U. S. Supreme Court banned the use of IQ tests in employment, except when linked to job performance via a Job analysis.

However, once a project grows past a few thousand lines, has multiple developers, and external-partner teams, fully integrated IDEs with code analysis and configuration management are all but mandatory.

However, Roland Watson, a cryptozoologist and Loch Ness Monster researcher, has criticized this analysis, stating that the object in the image is very unlikely to be a bloom of algae and zooplankton, since algae needs sunlight to grow, and the waters of Loch Ness are very dark, and nearly devoid of sunlight, 75 feet down.

However, the term is also used in time series analysis with a different meaning.

However, analysis of the wood indicated that they had degraded significantly in the seawater and mud, which had weakened their draw forces.

However, although computer analysis of the assembled data revealed that Clark Kent and Superman were the same person, Luthor dismissed the results because he believed that he ' knew ' that someone as powerful as Superman would never choose to live a normal human life.

However, the paleographic analysis of the Ancient Turkic runes, in turn, leads to a conclusion about very early forming date for the Turkic runic alphabet in Southern Siberia and Jeti-Su, not later than the middle of the 1st millennium BC.

However, the theory was revived and expanded by Elisabeth Sears in Shakespeare and the Tudor Rose ( 2002 ), and Hank Whittemore in The Monument ( 2005 ), an analysis of Shakespeare's Sonnets which interprets the poems as a poetic history of Queen Elizabeth, Oxford, and Southampton.
