The 3′-end (three prime end) of a strand is so named due to it terminating at the hydroxyl group of the third carbon in the sugar-ring, and is known as the tail end. The 3′-hydroxyl is necessary in the synthesis of new nucleic acid molecules as it is ligated (joined) to the 5′-phosphate of a separate nucleotide, allowing the formation of ...
One such characteristic is the length of the 3′-UTR, which in the mammalian genome has considerable variation. This region of the mRNA transcript can range from 60 nucleotides to about 4000. [ 3 ] On average the length for the 3′-UTR in humans is approximately 800 nucleotides, while the average length of 5'-UTRs is only about 200 ...
3' untranslated region (3'-UTR). Also three-prime untranslated region, 3' non-translated region (3'-NTR), and trailer sequence.. 3'-end. Also three-prime end.. One of two ends of a single linear strand of DNA or RNA, specifically the end at which the chain of nucleotides terminates at the third carbon atom in the furanose ring of deoxyribose or ribose (i.e. the terminus at which the 3' carbon ...
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. In the backbone of DNA the 5' carbon ...
A plant may extend stolons outward to reach a length of 15 to 45 centimetres (6 to 18 in) by the end of a growing season. [4] In ideal experimental conditions stolons may grow as much as 5.71 centimetres (2.25 in) per day. [5] When blooming or going to seed it has short, upright stalks that may be anywhere from 1–30 centimeters tall. [3]
Achene – dry indehiscent fruit that have one seed and are formed from a single carpel; the seed is distinct from the fruit wall. Caryopsis – the pericarp and seed are fused together, the fruit of many grasses. [18] Drupe – outer fleshy part that surrounds a shell with a seed inside.
The set of prime ends of the domain B is the set of equivalence classes of chains of arcs converging to a point on the boundary of B. In this way, a point in the boundary may correspond to many points in the prime ends of B, and conversely, many points in the boundary may correspond to a point in the prime ends of B. [3]
The upper angle between one part of a plant and another, e.g. the stem and a leaf. axile On an axis; of a placenta, on the central axis of the ovary. axillary Borne in or arising from the axil, usually referring to the axil of a leaf. axis The main stem of a whole plant or inflorescence; also, the line along which this stem extends.
