When nucleotides join together into a polynucleotide, they form a long chain known as a nucleic acid, such as DNA or RNA. This process involves the formation of phosphodiester bonds between the sugar of one nucleotide and the phosphate group of another, creating a backbone that holds the sequence of nitrogenous bases. The specific arrangement of these bases encodes genetic information essential for biological functions.
What else can I help you with?
Why is DNA called polynucleotide?
DNA is called a polynucleotide because it is composed of multiple nucleotides linked together in a chain. Each nucleotide consists of a sugar molecule, a phosphate group, and a nitrogenous base, and when these nucleotides join together through phosphodiester bonds, they form a long chain called a polynucleotide.
The enzyme that can join pieces of DNA together is?
DNA-polymerase synthesizes DNA molecules, while DNA-ligase ca join DNA pieces together by making phosphodiester bond.
How does 4 nucleotides polymerize to form nuclic acid?
Nucleotides polymerize through a condensation reaction between the phosphate group of one nucleotide and the sugar group of another nucleotide. This forms a phosphodiester bond, linking the nucleotides together to form a nucleic acid chain. DNA and RNA are examples of nucleic acids formed by polymerization of nucleotides.
What make up the rugs of the DNA molecule?
The DNA molecule is composed of nucleotides, which consist of a sugar molecule (deoxyribose), a phosphate group, and one of four nitrogenous bases (adenine, thymine, cytosine, or guanine). These nucleotides join together in a specific sequence to form the double helix structure of the DNA molecule.
What are DNA pieces called?
on the outsides there is phosphate and a sugar called dyoxiribose...spelling... and the insides are like rungs on a ladder, theres adenine which pairs up with thymine... and guanine which pairs up with cytosine
Why is DNA called polynucleotide?
DNA is called a polynucleotide because it is composed of multiple nucleotides linked together in a chain. Each nucleotide consists of a sugar molecule, a phosphate group, and a nitrogenous base, and when these nucleotides join together through phosphodiester bonds, they form a long chain called a polynucleotide.
How does DNA reproduce itself?
DNA reproduces through a set process that begins when it unzips and uncoils. Next, two polynucleotide chains are produced and adenine lines up with thymine. Cytosine lines up with guanine, and then hydrogen bonds form between the pairs. Enzymes join the nucleotides together, and two new DNA molecules are formed.
When was Join Together - song - created?
Join Together - song - was created on 1972-05-22.
The enzyme that can join pieces of DNA together is?
DNA-polymerase synthesizes DNA molecules, while DNA-ligase ca join DNA pieces together by making phosphodiester bond.
What Enzymes could create a bond between the adjacent unjoined nucleotides?
DNA polymerase is an enzyme that catalyzes the formation of a phosphodiester bond between adjacent nucleotides during DNA replication. RNA polymerase is responsible for synthesizing RNA molecules by joining nucleotides together.
How does nucleotide dehydration synthesis contribute to the formation of DNA and RNA molecules?
Nucleotide dehydration synthesis is a process where nucleotides join together to form DNA and RNA molecules. During this process, a water molecule is removed, allowing the nucleotides to bond together. This contributes to the formation of DNA and RNA by creating the long chains of nucleotides that make up these molecules.
How does 4 nucleotides polymerize to form nuclic acid?
Nucleotides polymerize through a condensation reaction between the phosphate group of one nucleotide and the sugar group of another nucleotide. This forms a phosphodiester bond, linking the nucleotides together to form a nucleic acid chain. DNA and RNA are examples of nucleic acids formed by polymerization of nucleotides.
What is inside DNA?
Deoxyribonucleic acid is a polymer composed of two polynucleotide chains that coil around each other to form a double helix. DNA is comprised of four structure blocks called nucleotides: adenine (A), thymine (T), guanine (G), and cytosine (C). The nucleotides join to one another (A with T, and G with C) to shape substance bonds called base matches, which interface the two DNA strands.
Which nucleotides join to form based pairs?
A-T and G-C
How do the radioactively labeled dideoxynucleotides terminate DNA synthesis?
Dideoxynucleotides have no OH group on the sugar of the nucleotides, only H's. That means phosphate groups can't react with the sugar to form a phosphodiester bond to join two nucleotides together, so DNA syntheses is terminated
What enzyme joins the nucleotides of a DNA strand together?
That depends on the process. During DNA replication, The nucleotides of the lagging strand (Okazaki fragments) are connected by DNA ligase. In transcription, the nucleotides of RNA are connected by RNA polymerase II.DNA Polymerse
What if T substituted for A in DNA nucleotides?
If the strands separate then it'll be a mutation that can be good, bad, or indifferent. T doesn't connect with T again if the strand were to join together so there would be a mistake there.
