The first step of nucleotide synthesis is the formation of a nucleoside (the nitrogenous base joined to a sugar). The sugar involved in the synthesis and structure of a nucleotide may be either ribose or deoxyribose; in the latter case, the prefix 'deoxy' may be added before the name of the nucleoside in all cases except Uracil. A functional group of phosphate is then esterified to the sugar, creating a nucleotide. The phosphate group may consist of one, two, or three phosphates, forming monophosphates, diphosphates, or triphosphates, respectively.
What else can I help you with?
In nucleic acids the free hydroxyl group is attached to the carbon of the sugar.?
In nucleic acids, the free hydroxyl group is typically attached to the 3' carbon of the sugar molecule in the nucleotides. This hydroxyl group is crucial for the formation of phosphodiester bonds during the polymerization of nucleotides into a nucleic acid strand. The presence of this hydroxyl group allows for the attachment of additional nucleotides, facilitating the growth of the nucleic acid chain. In contrast, the 5' carbon of the sugar is usually attached to a phosphate group, which plays a key role in linking nucleotides together.
Can you see nucleotides through a microscope?
No, you cannot see individual nucleotides through a microscope.With an electron microscope, it is just possible to make out some very large molecules (macromolecules), such as individual strands of DNA. But the resolution (resolving power) of even an electron microscope cannot distinguish free (uncombined) nucleotides.
What are the pathway by which plants obtain atmospheric nitrogen?
Plants primarily obtain atmospheric nitrogen through a process called nitrogen fixation, which is facilitated by certain bacteria, such as rhizobia, that live in symbiosis with the roots of leguminous plants. These bacteria convert atmospheric nitrogen (N₂) into ammonia (NH₃), which plants can then absorb and utilize. Additionally, some free-living soil bacteria and cyanobacteria also perform nitrogen fixation. Once converted, nitrogen compounds can be taken up by plants and incorporated into essential biomolecules like amino acids and nucleotides.
What is the name of the enzyme that would have placed nucleotides into the replicating DNA in the correct order?
The enzyme responsible for placing nucleotides into replicating DNA in the correct order is called DNA polymerase. DNA polymerase adds complementary nucleotides to the growing DNA strand during replication, following the rules of base pairing (A with T and C with G).
What are the monomers of DNA made of?
its made up of nucleotides
What are free floating nucleotides?
Free floating nucleotides are individual units of nucleic acids, such as DNA or RNA, that are not part of a larger nucleic acid chain. These nucleotides can serve as building blocks for synthesizing new DNA or RNA strands. They are also important for various cellular processes, such as protein synthesis and energy storage.
Enzymes used to add free nucleotides when replicating DNA?
DNA polymerase can add free-floating nucleotides to the DNA after it has been "unzipped" by the helicase. It also checks for any awnsers.
What are Free Nucleotides?
Free Nucleotides are ones that exist in the form of a triphosphate or three phosphates. When it is combined in DNA, the nucleotide loses two phosphates and only one phosphate is included in the DNA.
What attaches free nucleotides to the growing DNA strand?
During DNA replication, DNA polymerase binds free DNA nucleotides to an unzipped DNA strand. During transcription, RNA polymerase binds free RNA nucleotides to the unzipped anti-sense DNA strand.
What are free nucleotides made up of?
Sugar phosphate,phosphoral and nitrogeneous base
Why do the free nucleotides significant to the living cell?
Free nucleotides are essential building blocks for the synthesis of DNA and RNA molecules in cells. They are required for processes like DNA replication, gene expression, and protein synthesis. Without free nucleotides, cells would not be able to replicate, grow, or carry out their normal functions.
What is the rule to join the free nucleotides to the exposed bases of the DNA?
watson-base pairing
What is the enzyme responsible for attaching free floating nucleotides to an open strand of DNA for replication?
DNA polymerase is the enzyme responsible for attaching free floating nucleotides to an open strand of DNA during replication. It adds nucleotides in a specific order dictated by the template DNA strand.
In nucleic acids the free hydroxyl group is attached to the carbon of the sugar.?

Do nucleotides only pair with certain other nucleotides based on their properties?
Yes, nucleotides pair with specific complementary nucleotides based on their chemical properties.
