Tuition Center Singapore Secondary Math Tuition – Lowest Common Multiple (LCM)   1.The smallest common multiple among the common multiples of two or more numbers is called the lowest common multiple (LCM) of the given numbers. Example 1 Multiples of 8: 8, 16, 24, 32, 40, 48, …Multiples of 12: 12, 24, 36, 48, 60, … The LCM of 8 and 12 is 24.   2.Another method to find the LCM of two or more numbers is by using prime fractorisation Example 2 Find the lowest common multiple of 24 and 90. 24 = 23 x 390 = 2 x 32 x 5 LCM = 23 x 32 x 5 = 360   3.We can also find the LCM of two or more numbers by repeatly dividing the numbers by their prime factors Example 3 Find the lowest common multiple of 21, 63 and 105. 3)21, 63, 1057)  7, 21,    35   )  1,  3,       5 LCM = 3 ...

Tuition Center Singapore JC H2 H1 Biology Tuition – Basic Tools in Genetic Engineering   Basic Tools in Genetic Engineering Key Technique 1 : Restriction enzymes (endonucleases)  Restriction enzymes are synthesized naturally by ribosomes in bacteria. Different species of bacteria synthesize specific types of restriction enzymes which protect them from viruses by degrading incoming viral DNA. The bacterial genome is protected from degradation by its own restriction enzyme by addition of a methyl group (-CH3) to an adenine (A) or cytosine (C) at the restriction site, whereas the DNA sequence of an invading virus is generally not methylated. Each restriction enzyme (endonuclease) recognizes a specific sequence of 4 to 8 nucleotide bases on the DNA molecule known as restriction site ...
