WebIntact circular DNA extracted from bacterial cells has a linking deficit; that is, the DNA has fewer duplex turns than would be found in a nicked or linear molecule of the same … WebCircular DNA also circumvents the Hayflick limit (thus allowing it to be "immortal"), which is the number of times a cell population can divide before it stops, presumably due to the shortening of telomeres, the sequences at the end of the chromosomes. Since circular DNA lacks telomeres, it does not get shorter with each replication cycle. reading aerial photo

WebApr 14, 2024 · Circular RNAs (circRNAs) are a recently discovered class of RNAs derived from protein-coding genes that have important biological and pathological roles. They are formed through backsplicing during co-transcriptional alternative splicing; however, the unified mechanism that accounts for backsplicing decisions remains unclear. Factors that … Web(A) A circular DNA molecule organized into six topologically independent domains, which are defined in an unknown fashion inside cells by a mechanism that prevents rotation of the double helix. It is not yet certain what macromolecule in living bacterial cells is responsible for this domain organization.
