RNA Primer
The enzyme responsible for extending the new DNA strand by adding nucleotides is DNA polymerase. It reads the template strand and adds complementary nucleotides to form a new DNA strand. DNA polymerase can only add nucleotides in the 5' to 3' direction.
The phosphate is attached to the 5' carbon of the sugar in a nucleotide.
The 5' end of a nucleotide has a phosphate group attached to the 5th carbon of the sugar molecule, while the 3' end has a hydroxyl group attached to the 3rd carbon. This structural difference affects how nucleotides are linked together in DNA and RNA strands.
Nucleic acids consist of either one or two long chains of repeating units called nucleotides, which consist of a nitrogen base (a purine or pyrimidine) attached to a sugar phosphate.
They are attached to a deoxyribose sugar.
The first nucleotide must be attached to a short RNA primer to provide a free 3' hydroxyl group for DNA polymerase to extend from. DNA polymerase starts adding nucleotides to this RNA primer to begin DNA replication.
THat would be the enzyme DNA Polymerase III which attaches free floating nucleotides to the parent strand. But remember, they can only be attached to a free 3' position!
Nucleotides are attached to each other through a sugar-phosphate backbone. The phosphate group of one nucleotide is attached to the sugar molecule of another nucleotide, forming a chain. Additionally, nucleotides are also attached to nitrogenous bases, such as adenine, cytosine, guanine, or thymine (in case of DNA) or uracil (in case of RNA).
The enzyme responsible for extending the new DNA strand by adding nucleotides is DNA polymerase. It reads the template strand and adds complementary nucleotides to form a new DNA strand. DNA polymerase can only add nucleotides in the 5' to 3' direction.
The connection between nucleotides is between the sugar of the first nucleotide and the phosphate of the second. These are covalent bonds yielding a covalently attached sugar-phosphate backbone.
The phosphate is attached to the 5' carbon of the sugar in a nucleotide.
The 5' end of a nucleotide has a phosphate group attached to the 5th carbon of the sugar molecule, while the 3' end has a hydroxyl group attached to the 3rd carbon. This structural difference affects how nucleotides are linked together in DNA and RNA strands.
cytosine, thymine, adenine, and guanine..
A nucleoside is composed of a nitrogenous base and a sugar molecule, while a nucleotide is a nucleoside with one or more phosphate groups attached. Nucleotides are the building blocks of nucleic acids like DNA and RNA, while nucleosides are not involved in DNA or RNA synthesis.
Nucleic acids consist of either one or two long chains of repeating units called nucleotides, which consist of a nitrogen base (a purine or pyrimidine) attached to a sugar phosphate.
They are attached to a deoxyribose sugar.
The monomers of DNA are called nucleotides, and the polymer is a polynucleotide.There are four different nucleotides in DNA called A, T, G, and C for the nitrogenous base sidegroup (adenine, thymine, guanine, and cytosine respectively) attached to the sugar-phosphate backbone (deoxyribose-phosphate) of a nucleotide. These nucleotides can be joined in any order, permitting the "spelling" of an unlimited number of different genetic "words".
