Directionality, in molecular biology and biochemistry, is the end-to-end chemical orientation of a single strand of nucleic acid. In a single strand of DNA or RNA, ...
In molecular biology and genetics, upstream and downstream both refer to relative positions of genetic code in DNA or RNA.Each strand of DNA or RNA has a 5' end and a 3' end, so named for the carbon position on the deoxyribose (or ribose) ring.
In molecular biology, a reading frame is a way of dividing the sequence of nucleotides in a nucleic acid (DNA or RNA) molecule into a set of consecutive, non-overlapping triplets. Where these triplets equate to amino acids or stop signals during translation, they are called codons.
Molecular biology is the study of the molecular underpinnings of the biological phenomena, focusing on molecular synthesis, modification, mechanisms and interactions. Biochemistry is the study of the chemical substances and vital processes occurring in living organisms .
Helicase polarity, which is also deemed "directionality", is defined as the direction (characterized as 5'→3' or 3'→5') of helicase movement on the DNA/RNA single-strand along which it is moving. This determination of polarity is vital in f.ex. determining whether the tested helicase attaches to the DNA leading strand, or the DNA lagging ...

"Influenza is a family of viruses — a group that has similarities in the way that their biology works," Dr. Stuart Ray, professor of medicine and oncology at Johns Hopkins University School of ...
Directionality sounds very similar to sense (molecular biology). Please explain the differences in the article. -Pgan002 13:53, 24 February 2011 (UTC) There are quite distinct: directionality is a way of saying 'which way you're travelling' along a DNA or RNA strand (e.g. from 5' to 3')
