What have we learned about RNA structure and function so far? Although RNA is a single-stranded molecule, researchers soon discovered that it can form double-stranded structures, which are ...

RNA is similar to DNA but contains uracil instead of thymine (T) and has a single-stranded structure. Comparison of a single-stranded RNA and a double-stranded DNA with their corresponding nucleobases ...

mRNA is created during transcription. During the transcription process, a single strand of DNA is decoded by RNA polymerase, and mRNA is synthesized. Physically, mRNA is a strand of nucleotides ...

Ribonucleic acid (RNA) molecules may be best known for their job ferrying the genetic information encoded in DNA to a cell's ...

If you imagine a double-helix strand of DNA as a twisted ladder, these nitrogenous base pairs are the rungs. There are also purines and pyrimidines in RNA, but since it is single-stranded ...

The Dicer enzyme trims this pri-miRNA, and once the other strand is discarded, the miRNA recruits the Argonaute protein to form an RNA-induced silencing complex (RISC). The single-stranded miRNA ...

Researchers have developed a map of normal hematopoietic cell differentiation and used it to examine how aberrant differentiation can lead to #AML, according to results presented by Andy Zeng, PhD, at ...

The nine-subunit non-catalytic core shares structural similarities to bacterial 3’ to 5’ phosphorolytic exoribonucleases such as PNPase, including a prominent central channel that is large enough to ...

A short piece of single-stranded RNA about 21 to 23 bases in length that regulates the expression of genes. MicroRNAs function by binding to a matching piece of messenger RNA that encodes a protein ...

functionalized with Probe (single stranded complementary oligonucleotide fragment) and ethidium bromide (EB), for detection of enteroviral RNA," says professor of physics Jussi Toppari from the ...
