Elizabeth Blackburn
The work of Elizabeth Blackburn concerns the performance and production of telomeres, which are the ends of eukaryotic chromosomes. Telomerase specifies the sequence of telomeric DNA by using a short sequence of the telomerase RNA moiety as the guide for DNA synthesis. Therefore, telomeric DNA is a vital chromosomal component which is unusual as it is made by copying an RNA sequence; which is an extremely specialised, distinctive mechanism.
Her goal is to grasp the role of telomerase in cells and how it works. She wants to achieve a further understanding of the function of telomerase. She is trying to figure out whether telomerase has any additional purposes besides polymerizing telomeric DNA. She has been able to change the way telomere is made by changing telomerase which has led to the finding that cell cycling, growth and division are compromised in completely different ways. However these responses are

He also developed wheat to produce high yields. His most notable accomplishment was the breeding and formation of "Federation" wheat. His accomplishments extended wheat-growing areas, particularly in New South Wales, and resulted in Australia's turning into a world leader in wheat exports. William Farrer was in favour of large-scale ringbarking of eucalypts, Disputing that it might quadruple the carrying capability of undeveloped bushland.
Federation wheat is the most popular form of wheat. It is drought resistant, rust fungus resistance and very high yielding. It has formed the basis of the Australian wheat industry but with the high yielding crops has brought the expansion of the wheat industry into areas where rainfall is not certain and no rain can cause devastating crop failures which will mean the farmers in those areas will lose their money.
