WebThe DNA molecule consists of 4 nitrogen bases, namely adenine (A), thymine (T), cytosine (C) and Guanine (G), which ultimately form the structure of a nucleotide. The A and G are purines, and the C and T are pyrimidines. The two strands of DNA run in opposite directions. These strands are held together by the hydrogen bond that is present ...

Complementary Base Pairing: Definition & Explanation
WebTwo primers are used in each PCR reaction, and they are designed so that they flank the target region (region that should be copied). That is, they are given sequences that will make them bind to opposite strands of the … WebNov 15, 2009 · 5 Answers. Probably the most efficient way to do it, if the string is long enough: import string def complementary_strand (self, strand): return strand.translate (string.maketrans ('TAGCtagc', 'ATCGATCG')) This is making use of the translate and maketrans methods. You can also move the translate table creation outside the function: relative isotopic mass of copper-63
