how to generate a pseudo random binary sequence and convert to DNA sequence

I have binary sequence (100101110010010100100010101011010010) and sequence is divided into 3-bit binary sequences

100 101 110 010 010 100 100 010 101 011 010 010

each 3-bit sequence is converted to corresponding DNA codes using the DNA coding rule, as follows 000 ( 00-A,01-C 10-G,11-T) 001(00-A,01-G,10-C,11-T) 010(00-C,01-A,10-T,11-G) 011( 00-C ,01-T,10-A,11-G) 100( 00-G, 01-A,10-T,11-C) 101(00-G,01-T,10-A, 11-C) 110(00-T,01-C,10-G,11-A) 111( 00-T,01-G,10-C,11-A) . please help me how write code in matlab

I see that the nucleotide coding changes according to the three bit pattern, but I am uncertain which two bits are coding for the nucleotide in the three bit pattern. Is it always the same two bits, or does it change according to the three bit pattern.

It changes according to the three bit pattern

Actually i have no idea of this concept. It is given like a standard table to convert 3-bit sequences into dna codes.
