Yes, microRNAs (miRNAs) are small non-coding RNA molecules that are single-stranded. They typically range from 20-24 nucleotides in length and function in post-transcriptional regulation of gene expression.
It would be single stranded when it has been synthetically made like a probe.
It is single stranded RNA. Importantly, it is also a segmented genome that allows it to have large genetic diversity.
When double stranded DNA is unwound into single stranded DNA, single-strand binding proteins bind to each single stranded DNA strand and prevent the two strands from reattaching to each other, allowing DNA replication to continue.
Ribonucleic acid (RNA) is the polynucleotide that is typically single-stranded. Unlike DNA, which is double-stranded and forms a double helix, RNA can exist in various forms, including messenger RNA (mRNA), transfer RNA (tRNA), and ribosomal RNA (rRNA), all of which are single-stranded. This single-stranded structure allows RNA to perform diverse functions in cellular processes, including protein synthesis and regulation.

No, RNA is not always single stranded. It can exist as single stranded or double stranded depending on its function and structure.
RNA is typically single-stranded, unlike DNA which is double-stranded.
Yes, tRNA is single-stranded.
RNA is always single stranded. DNA, on the other hand, can exist as either single-stranded or double-stranded.
RNA is typically single-stranded, while DNA is double-stranded.
RNA is typically single-stranded, unlike DNA which is double-stranded.
Plasmids can be either single or double stranded, but most commonly they are double stranded.
The DNA in a virus can be either single-stranded or double-stranded, depending on the type of virus.
single stranded RNA (positive sense)
DNA is double stranded.
DNA is double stranded.
tRNA, or transfer RNA, is a single stranded molecule. The only double stranded RNA is dsRNA, or double stranded RNA. They are typically found in viruses.
