Starch/glucose is the food prepared during photosynthesis. if a plant has photosynthesised, it means it has produced its products. you can check this by doing the starch test. boil the leaf which will kill the cells and then dip it in ethanol to extract the green colour. then add the iodine. if the leaf turns blue/black after adding the iodine, this means starch is present and starch is the extra glucose produced (product)

what is the maximum number of amino acids that can be specified by a codon consisting of a sequence of four bases
vichka [17]

Answer:

64.

Explanation:

It is 64 because there are 20 amino acids with four bases ( A,T,C and G).

and genetic code can be read in triplets and also the four bases can occupy the positions. Eachh amino acid can be coded by the triplet codons. A triplet codon shows three nucleotides of the mRNA template that can code for amino acid

Therefore the number of codons is 4×4×4= 64.
