Answer-

Your code is here-

  • dna1 = ('ATTGCC')
  • W= dna1.count('A') //letter occurrences count function
  • X= dna1.count('T')
  • Y= dna1.count('G')
  • Z= dna1.count('C')
  • puts "{"+ "'A'=>" + "#{W}"+ "," + "'T'=>" + "#{X}" + "," +"'G'=>" + "#{Y}" +"," + "'C'=>" + "#{Z}" + "}"

perform the following using Ruby language A DNA strand is represented by a string of the characters A, C, G, and T, each of which represents a nucleotide. Each nucleotide has its complement as indicated by this Ruby hash: NUCLEOTIDE_COMPLEMENT = { 'A' => 'T', 'T' => 'A', 'C' => 'G', 'G' => 'C' } The reverse-complement of a DNA string is a new string in which each nucleotide is replaced by its complement and the string is reversed. Reverse-complements...

Given a binary string of zeros (0) and ones (1). You have to build a circuit that counts the number of occurrences of string '01' within the given string. For example, given string '01000110001001', there are 4 occurrences of '01' and output have to show number of occurance each time '01' occured. Use a FSM and a counter (built from D flip-flops) to implement this circuit. It is guaranteed that the number of occurrences is not more than 31 (you...
