The 5′ is upstream; the 3′ is downstream. DNA and RNA are synthesized in the 5′-to-3′ direction. Directionality, in molecular biology and biochemistry, is the end-to-end chemical orientation of a single strand of nucleic acid.
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.
A single-stranded non-circular DNA molecule has two non-identical ends, the 3' end and the 5' end (usually pronounced "three prime end" and "five prime end"). The numbers refer to the numbering of carbon atoms in the deoxyribose, which is a sugar forming an important part of the backbone of the DNA molecule.

The copied region is bounded by the known sequence, at either the 5' or 3' end. The protocols for 5' or 3' RACES differ slightly. 5' RACE-PCR begins using mRNA as a template for a first round of cDNA synthesis (or reverse transcription) reaction using an anti-sense (reverse) oligonucleotide primer that recognizes a known sequence in the middle ...
This gives nucleic acids directionality, and the ends of nucleic acid molecules are referred to as 5'-end and 3'-end. The nucleobases are joined to the sugars via an N -glycosidic linkage involving a nucleobase ring nitrogen ( N -1 for pyrimidines and N -9 for purines) and the 1' carbon of the pentose sugar ring.
Although they are called untranslated regions, and do not form the protein-coding region of the gene, uORFs located within the 5' UTR can be translated into peptides. [1] The 5' UTR is upstream from the coding sequence. Within the 5' UTR is a sequence that is recognized by the ribosome which allows the ribosome to bind and initiate translation.
Cap analysis of gene expression (CAGE) is a gene expression technique used in molecular biology to produce a snapshot of the 5′ end of the messenger RNA population in a biological sample (the transcriptome).
