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 ...
This is a rhizomatous perennial grass with erect stems growing up to 1.7 meters tall. The leaf blades can be nearly a meter long in ssp. mollis, and up to 1.5 centimeters wide. The flower spike is up to 34 centimeters long by 2 wide. Each spikelet may be up to 3.4 centimeters long and contain up to six florets. There are two subspecies.
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]
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 ...
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.
It is also known as timothy-grass, meadow cat's-tail or common cat's tail. [3] It is a member of the genus Phleum , consisting of about 15 species of annual and perennial grasses. It is probably named after Timothy Hanson, an American farmer and agriculturalist said to have introduced it from New England to the southern states in the early 18th ...
Most grass seed germinates when soil temperatures are around 55 to 60 degrees F. 2. Figure out what kind of grass you have. You’ll want to plant the same type to avoid a patchy appearance in the ...
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]
