T. aquaticus is a bacterium that lives in hot springs and hydrothermal vents, and Taq polymerase was identified as an enzyme able to withstand the protein-denaturing conditions (high temperature) required during PCR. Therefore, it replaced the DNA polymerase from E. coli originally used in PCR. Taq's optimum temperature for activity is 75â80 Â°C, with a half-life of greater than 2 hours at 92.5 Â°C, 40 minutes at 95 Â°C and 9 minutes at 97.5 Â°C, and can replicate a 1000 base pair strand of DNA in less than 10 seconds at 72 Â°C.
Glucose and fructose are monosaccharides and are the building blocks of sucrose, a disaccharide. Thus, disaccharides are just a pair of linked sugar molecules. They are formed when two monosaccharides are joined together and a molecule of water is removed -- a dehydration reaction.
A molecule of sucrose. Glucose and fructose are monosaccharide sugars. A monosaccharide is the smallest unit of sugar, mono meaning 1. Sucrose is commonly called table sugar and is a disaccharide. A disaccharide is a sugar that is made up of two sugar units, di meaning 2.Sucrose is produced as glucose and fructose are joined together by a condensation reaction.In the process a water molecule is eliminated. See the following equation. disaccharide is a sugar that is made up of two sugar units, di meaning 2. Sucrose is produced as glucose and fructose are joined together by a condensation reaction.
