Lactose intolerance is when your body can't break down or digest lactose. Lactose is a sugar found in milk and milk products. Lactose intolerance happens when your small intestine does not make enough of a digestive enzyme called lactase. Lactase breaks down the lactose in food so your body can absorb it.
Explanation:
<span>Proto-oncogenes are genes that normally help cells grow. When a proto-oncogenemutates (changes) or there are too many copies of it, it becomes a "bad" gene thatcan become permanently turned on or activated when it is not supposed to be. When this happens, the cell grows out of control, which can lead to cancer.....Is this what you need ?</span>
Methionine-methionine leucinelysine that a mutation in the DNA occurs so that the fourth base (counting from the 5' end) of the messenger RNA.
mRNA codons are read from 5' to 3' , and they specify the order of amino acids in a protein from N-terminus (methionine) to C-terminus. The mRNA sequence is: 5'-AUGAUCUCGUAA-5'
Ciodons which is broke the sequence into a series of three-nucleotide units. There are three-letter nature of codons that the four nucleotide found in mRNA such as A, U, G, and C all these can produce a total of 64 different combinations. The sequence of the tRNA anti-codon is 3'-UGC-5' and the tRNA will carry the amino acid which is the encoded by the codon.
