What is the backbone of nucleic acid polymers composed of?
The backbone of nucleic acid polymers is composed of alternating sugar and phosphate groups. In DNA, the sugar is deoxyribose, while in RNA, the sugar is ribose. The phosphate groups link the sugars together to form a chain.
Is a strong bond used to bond the nucleic acid monomers together along one chain?
Yes, a strong bond called a phosphodiester bond is used to bond nucleic acid monomers (nucleotides) together along one chain. This bond forms between the phosphate group of one nucleotide and the sugar group of the adjacent nucleotide, creating a sugar-phosphate backbone in DNA and RNA molecules.
Is a nucleic acid a monomer or a polymer?
Nucleic acids are polymers made up of monomeric units called nucleotides. Each nucleotide consists of a phosphate group, a sugar molecule, and a nitrogenous base. Multiple nucleotides linked together form a nucleic acid chain, which can be either DNA or RNA.
What is an example of a sugar phosphate backbone?
DNA and RNA molecules have a sugar phosphate backbone. In DNA, the sugar is deoxyribose, while in RNA it is ribose. The phosphate groups link the sugar molecules together forming a linear chain.
What is the polymer for a nucleic acid?
DNA (deoxyribonucleic acid) and RNA (ribonucleic acid) are both polymers, with repeating units (monomers) of nucleotides, which are made up of: - a nitrogenous base - a 5-carbon sugar (deoxyribose or ribose) - a phosphate group
What is the backbone of nucleic acid polymers composed of?
The backbone of nucleic acid polymers is composed of alternating sugar and phosphate groups. In DNA, the sugar is deoxyribose, while in RNA, the sugar is ribose. The phosphate groups link the sugars together to form a chain.
Which linkage forms the backbone of a nucleic acid?
A phosphodiester linkage forms the backbone of a nucleic acid by connecting the 3' carbon of one nucleotide to the 5' carbon of another nucleotide in a chain. This linkage creates a sugar-phosphate backbone that provides stability to the nucleic acid structure.
What is the chemical bond connecting one nucleotide with the next one along the nucleic acid chain?
The chemical bond connecting one nucleotide with the next one along the nucleic acid chain is a phosphodiester bond. This bond forms between the phosphate group of one nucleotide and the sugar group of the next nucleotide, creating a backbone of alternating sugar and phosphate groups in the nucleic acid chain.
Does DNA or rna have phosphate groups?
Yes. Phosphorus is contained in the phosphates attached to the deoxyribose molecules on the double helix strands. (The stabilizing crossbars of the double helix are comprised of the four nucleic acids, paired off as adenosine-thymine, or A-T, and guanine-cytosine, or C-G).
What forms the backbone of the DNA double helix molecule?
The backbone of a DNA chain is sugar and phosphate groups of each nucleotide.
What is the basic building block of a nucleic-acid chain?
The basic building block of a nucleic-acid chain is a nucleotide. Each nucleotide consists of a phosphate group, a sugar molecule (such as ribose or deoxyribose), and a nitrogenous base (adenine, thymine, cytosine, or guanine). Multiple nucleotides link together through phosphodiester bonds to form a nucleic-acid chain.
Subunit of DNA consisting of a nitrogeneous base a sugar and a phosphate group?
A nucleotide is the subunit of DNA that consists of a nitrogenous base (adenine, cytosine, guanine, thymine), a sugar (deoxyribose), and a phosphate group. These nucleotides are the building blocks of DNA molecules.
Are nucleic acids and nucleotides the same thing?
No, nucleic acids are biopolymers made up of nucleotides linked together in a chain. Nucleotides are the building blocks of nucleic acids, consisting of a phosphate group, a sugar molecule, and a nitrogenous base.
What is an antinucleotide?
An antinucleotide is a molecule that is structurally similar to a nucleotide but contains modifications that prevent it from being incorporated into a nucleic acid chain. These modifications can include altered sugar groups, modified bases, or altered phosphate groups. Antinucleotides are often used in research and medicine to study nucleic acid interactions or as therapeutic agents.
What is a pentose joined to a nitrogenous base and a phosphate group?
That is a nucleotide, which is the basic building block of nucleic acids like DNA and RNA. The pentose sugar provides the backbone structure, the nitrogenous base carries genetic information, and the phosphate group connects nucleotides together to form the nucleic acid chain.
What joins the deoxyribose sugars together in a chain?
phosphodiesterbonds
Is a strong bond used to bond the nucleic acid monomers together along one chain?
Yes, a strong bond called a phosphodiester bond is used to bond nucleic acid monomers (nucleotides) together along one chain. This bond forms between the phosphate group of one nucleotide and the sugar group of the adjacent nucleotide, creating a sugar-phosphate backbone in DNA and RNA molecules.
