Question

(1 point) Automated chemical synthesis of DNA has made it possible to custom-order moderate-length DNA sequences from commercial suppliers. Assume that a single nucleotide weighs about 5.6 x 10-22 grams and that there are four kinds of nucleotides. If you wish to order all possible DNA sequences of a fixed length, at what length will your order exceed 85 kg? Length of nucleotides. If you wish to order all possible DNA sequences of a fixed length, at what length will your order exceed the mass of the earth, about 5.9736 x 1024 kg? Length of nucleotides.

Combinatorics problem! plz help!

Answer 1

= 80kg @ weight of a cach sequence 256x16 22 gm ton sequence have a weight Hace nosoti 285x103 85x163 ها » ة = 22 5.6022 26 n =1517 X10 7 I dength of 1.512x102 Hence na 1-517 41026 will have weight of equal to 8s eskg Nucleotides for order exceeding mass of eest have a weight =s. 9736x1024 kg = 5.993 X Jeta sequences nos.6x10-? - 22 5.97 364/024 s. 6810-22 nel:067x2049 Neuclotides Thength of 1:06771099 Neudotides cs canned with tam$canner UAN-2018 TFSS Wk
