Genetics with Mitosis and Meiosis

... S-phase, each chromosome consists of one strand of DNA. The DNA is copied during S-phase. So, after S-phase, each chromosome consists of two strands. When the DNA is coiled, the two strands are referred to as sister chromatids. The sister chromatids are what make chromosomes X-shaped. However, ...

Re: parallel binding of miRNA with mRNA

... heard of priming the template backwards (parallel). I have never heard of a natural system making parallel complementary transcripts from opposite strands of an antiparallel DNA duplex. OK, there might be something new for us to learn about here. To reiterate Jack, "Source?"

parallel binding of miRNA with mRNA

You cannot transcribe from both strands in the same direction. Would you mind to share your source?

parallel binding of miRNA with mRNA

if they are transcribed from opposite strands (on the same locus of course) than they are complementary and can bind to each other just as the DNA strands do

Re: parallel binding of miRNA with mRNA

... heard of a case of parallel complementary binding. However, you said that the miRNA and mRNA are complementary and are transcribed from opposite strands of DNA. This makes miRNA and mRNA antiparallel because their templates, the two strands of DNA, are both complementary and antiparallel.
