DNA nucleotide base-pairingElisha, Roberson
Base pair, in molecular biology, two complementary nitrogenous molecules that are connected by hydrogen bonds. Base pairs are found in double-stranded DNA and RNA, where the bonds between them connect the two strands, making the double-stranded structure
DNA:Deoxyribonucleic acid, a self-replication material present in nearly all living organisms. DNA can be found in every cell of your body and is what carries all your genetic information. You've probably heard that it takes the shape of a double helix (which it does!). RNA:Ribonucleic aci...
base pair n. A pair of nitrogenous bases, consisting of a purine linked by hydrogen bonds to a pyrimidine, that connects the complementary strands of DNA or of hybrid molecules joining DNA and RNA. The base pairs are adenine-thymine and guanine-cytosine in DNA, and adenine-uracil and guanine...

DNA replicationThe principles governing the replication fidelity of genomes are not fully understood yet. Watson and Crick's base-pairing principle for matched deoxyribonucleotide (DNA) bases can explain why the guanine-cytosine and adenine-thymine base pairs are approximately one hundred times more ...

1. DNA Replication and Transcription: During DNA replication, nucleotides are incorporated into the newly synthesized DNA strand, following the base-pairing rule. Each nucleotide added during replication corresponds to the complementary base on the parental DNA strand. Similarly, during transcription, nucl...
The heightened level of stability of the double-D-loop enables it to serve as an active template for the DNA repair events. The data establish DNA pairing and the formation of the double-D-loop as important first steps in the process of gene repair. 展开 ...
