WebApr 8, 2024 · The sgRNAs contain the same 3′ sequence as the genomic RNA; however, the 5′ ends are different from that of genomic RNA. In coronaviruses, a discontinuous transcription mode occurs during negative-sense RNA synthesis, referred to as leader-body fusion (Sola et al., 2015; Miller and Koev, 2000). Beginning from the 3′ end of the … WebThe answer is the discontinuous synthesis of this strand, but the other strand is continuously synthesised. Now, one of the template DNA strands is aligned as 3′ to 5′ at the replication fork, and as a result, it can be continuously copied by DNA polymerase, which extends the new DNA chain in a 5’ to 3’ direction. the brandwood centre the brandwood centre birmingham

"WebThis synthesis takes place in 5 direction enzymes that catalyze this DNA – polymerase synthesis of a strand called leading strands is continuous.
