In molecular biology, a polynucleotide (from Ancient Greek πολυς (polys) 'many') is a biopolymer composed of nucleotide monomers that are covalently bonded in a chain. [1] DNA (deoxyribonucleic acid) and RNA (ribonucleic acid) are examples of polynucleotides with distinct biological functions.
DNA is a polynucleotide as it is composed of simpler monomeric units called nucleotides; when double-stranded, the two chains coil around each other to form a double helix. [7] [8] In natural DNA, each nucleotide is composed of one of four nucleobases (cytosine [C], guanine [G], adenine [A] or thymine [T]), a sugar called deoxyribose, and a ...
Asymmetry in the synthesis of leading and lagging strands. Okazaki fragments are short sequences of DNA nucleotides (approximately 150 to 200 base pairs long in eukaryotes) which are synthesized discontinuously and later linked together by the enzyme DNA ligase to create the lagging strand during DNA replication.

One of the challenges Luu faced when creating Nookazon involved categorizing the many items of furniture and clothing within Animal Crossing. Animal Crossing: New Horizons contains thousands of individual items, all of which had to be catalogued with various colours in order to be listed on the website. To solve this problem, Luu used a ...
The sequence of nucleobases on a nucleic acid strand is translated by cell machinery into a sequence of amino acids making up a protein strand. Each group of three bases, called a codon , corresponds to a single amino acid, and there is a specific genetic code by which each possible combination of three bases corresponds to a specific amino acid.
Mr. Resetti, full name Sonny Resetti (also known in Japan as Mr. Reset (リセットさん, Risetto-san)), is a fictional character from the Animal Crossing series of video games by Nintendo. His first appearance was in the Nintendo 64 game Dōbutsu no Mori, released in Europe and North America on the GameCube as Animal Crossing. Mr.
In today's puzzle, there are six theme words to find (including the spangram). Hint: The first one can be found in the top-half of the board. Here are the first two letters for each word: FO. FE ...
It is possible that these sequence stretches form G-quadruplex like structures, which can suppress the expression of the related genes. The complementary cytosine rich sequences, on the other strand, may adopt another similar four stranded structure, the i-motif, stabilized by cytosine:cytosine non-canonical base pairs.
