"YKL074C" denotes the 74th ORF to the left of the centromere of chromosome XI and that the coding strand is the Crick strand (C). Another confusing term referring to "Plus" and "Minus" strand is also widely used. Whether the strand is sense (positive) or antisense (negative), the default query sequence in NCBI BLAST alignment is "Plus" strand.
The newly synthesized minus-strand cDNA copy of the 5’LTR is then transferred to the 3’LTR and used as a primer for reverse-transcription of the entire minus-strand sequence. An RNase H-resistant polypurine tract then serves as a primer for plus-strand synthesis of the 3’LTR and complementary PBS.
The minus-strand DNA is complete and spans the entire genome, while the plus strand spans only about two-thirds of the genome length and have variable 3' ends. But for the avihepadnaviruses they normally extend plus-strands almost all the way to the modified 5' end. [1]
By convention, the coding strand is the strand used when displaying a DNA sequence. It is presented in the 5' to 3' direction. Wherever a gene exists on a DNA molecule, one strand is the coding strand (or sense strand), and the other is the noncoding strand (also called the antisense strand, [3] anticoding strand, template strand or transcribed ...
DNA polymerase I removes the primer, replacing it with DNA, and DNA ligase joins the ends to make another molecule of double-stranded circular DNA. As a summary, a typical DNA rolling circle replication has five steps: [2] Circular dsDNA will be "nicked". The 3' end is elongated using "unnicked" DNA as leading strand (template); 5' end is ...
CccDNA is formed from rcDNA (relaxed circular DNA) through the removal of a viral polymerase on the 5’ end of the negative strand of DNA, the removal of the 5’ end of the plus strand, and the removal of one copy of the short terminal redundancy from the minus strand.
MS2 replicates its plus-strand genome by creating a minus strand RNA as a template. The virus then assembles, and the bacterial cell lyses , releasing new viruses. The virus was isolated in 1961 and its genome was the first to be fully sequenced, in 1976, providing a crucial understanding of genetic codes.
Due to the anti-parallel nature of DNA, this means the 3' end of the template strand is upstream of the gene and the 5' end is downstream. Some genes on the same DNA molecule may be transcribed in opposite directions. This means the upstream and downstream areas of the molecule may change depending on which gene is used as the reference.
