What did Thomas Cech discover?

In 1982, Thomas Cech studied the way RNA molecules from the microorganism Tetrahymena thermophila split into fragments. He discovered that RNA molecules inside a test tube split themselves using a complicated chemical reaction, despite the absence of a protein.

Who is Thomas Cech and Sidney Altman?

Thomas Robert Cech (born December 8, 1947) is an American chemist who shared the 1989 Nobel Prize in Chemistry with Sidney Altman, for their discovery of the catalytic properties of RNA. Cech discovered that RNA could itself cut strands of RNA, suggesting that life might have started as RNA.

What is Sidney Altman famous for?

Sidney Altman, (born May 7, 1939, Montreal, Que., Can.), Canadian American molecular biologist who, with Thomas R. Cech, received the 1989 Nobel Prize for Chemistry for their discoveries concerning the catalytic properties of RNA, or ribonucleic acid.

What is meant by RNA world?

The RNA world is a hypothetical stage in the evolutionary history of life on Earth, in which self-replicating RNA molecules proliferated before the evolution of DNA and proteins. The term also refers to the hypothesis that posits the existence of this stage.

What did Sidney Altman and Thomas Cech discovered?

The Nobel Prize in Chemistry 1989 was awarded jointly to Sidney Altman and Thomas R. Cech “for their discovery of catalytic properties of RNA.”

Why did Sid Altman win the Nobel Prize?

Who discovered nucleic acid?

Friedrich Miescher
Nucleic acids were discovered in 1868, when twenty-four-year-old Swiss physician Friedrich Miescher isolated a new compound from the nuclei of white blood cells.

Why the ribosome is a ribozyme?

By Sally Robertson, B.Sc. A ribozyme is a ribonucleic acid (RNA) enzyme that catalyzes a chemical reaction. The ribozyme catalyses specific reactions in a similar way to that of protein enzymes. Also called catalytic RNA, ribozymes are found in the ribosome where they join amino acids together to form protein chains.
