Short note on complementary nature of DNA |
| Answer» Nucleic acid\xa0sequence\xa0of bases that can form a double- stranded structure by matching base pairs. For example, the\xa0complementary sequence\xa0to C-A-T-G (where each letter stands for one of the bases in\xa0DNA) is G-T-A-C.\xa0Complementary DNA\xa0(cDNA) is the\xa0DNA\xa0produced on an RNA template by the action of reverse transcriptase (RNA-dependent\xa0DNA-polymerase). The sequence of the cDNA becomes\xa0complementary\xa0to the RNA sequence.\xa0In\xa0nature complementarity\xa0is the base principle of\xa0DNA\xa0replication and transcription as it is a property shared between two\xa0DNA\xa0or RNA sequences, such that when they are aligned antiparallel to each other, the nucleotide bases at each position in the sequences will be\xa0complementary. | |
