Each strand is a long chain of repeating
WebJul 20, 1998 · A segment of DNA that codes for the cell’s synthesis of a specific protein is called a gene. DNA replicates by separating into two … WebA polynucleotide chain has no branches. Each strand of a polynucleotide is made up of an alternate sugar and phosphate group. The purine or pyrimidine bases join to a repeating sugar-phosphate group in the polynucleotide backbone by N-glycosidic bonds 10 (Fig. 4.8).

WebEach chromosome is thus a long chain of nucleosomes, which gives the appearance of a string of beads when viewed using an electron microscope (Figure 2; Olins & Olins, 1974, 2003).
WebA new strand of DNA is made by an enzyme called DNA polymerase. It reads the original strand and matches complementary bases to the original strand. (The sugar-phosphate backbone comes with the new bases.) New strands attach to both sides of the original DNA, making two identical DNA double helices composed of one original and one new strand. WebEach daughter double strand of DNA is made up of a parent strand and a newly sythesised strand. Even though both strands in the parental DNA molecule are copied to form identical products, the two strands are copied in a slightly different manner from each other. This is due to the fact that DNA is always synthesised in a 5' to 3' direction.
WebAmino Acid Structure. Amino acids are the monomers that make up proteins. Each amino acid has the same core structure, which consists of a central carbon atom, also known as the alpha (α) carbon, bonded to an amino group (NH2), a carboxyl group (COOH), and a hydrogen atom. Every amino acid also has another atom or group of atoms bonded to the ... WebMay 25, 2024 · Too Long;Didn't Read (TL:DR) A polymer is a general term for any molecule that is a long string of smaller repeating parts formed by carbon-carbon bonds. The bonds can form long straight chains known as linear polymers, or parts can branch off from the chain, forming branched polymers. The polymers can also be cross-linked.
