cells and many viruses. It consists of two strands of nucleotides linked together in a structure resembling a ladder twisted into a spiral. In eukaryotic cells, the DNA is contained mainly in the nucleus and mitochondria. DNA can replicate itself and synthesize RNA. CompareRNA. See Note atgene...
RNA is always single-stranded and is often referred to as single-stranded ribonucleic acid. This can be seen in Figure 1 below. However, DNA can be either double-stranded or a single strand of DNA (ssDNA).Figure 1. The comparison between single-stranded RNA and double-stranded DNA. Image...
True or false? DNA contains thymine but RNA does not. True or false? Reverse transcriptase uses DNA as a template to synthesize RNA. True or false? DNA is single stranded in some viruses. A strand of DNA serves as a template (model) for the synthesis of RNA molecules. (a) True...
All previous samples of DNA which have been characterized have had molecular contents up around 120 million or more and molecular weights of 6 to 12 million. They have fitted the behavior patterns predicted for a twostrand chain held together by hydrogen bonding and wound in a helix. Robert L...
Specific sequences and a hairpin structure in the template strand are required for N4 viron RNA polymerase promoter recognition Coliphage N4 virion-encapsidated, DNA-dependent RNA polymerase (vRNAP) is inactive on double-stranded N4 DNA; however, denatured promoter-containing templa...

RNA-mediated double-strand break repair by end-joining mechanisms ArticleOpen access11 September 2024 Introduction Antisense long noncoding RNAs (lncRNAs), which often overlap with the transcripts encoded from the sense strand, constitute the largest sub-class of lncRNAs1,2. They have been shown to...
Premature termination (indicated by a lightning bolt) is usually facilitated by interactions between viral RNA sequences on the same strand (cis-interactions) or on separate strands (trans-interactions) of virus-derived RNA. In general, for plant-infecting positive-sense RNA viruses, i...
