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.
Do nucleotides need to be joined together in a specific order?
False :b
Which best describes the structure of a DNA molecule-?
a double helix- apex
What units are repeatedly joined together to form a strand of DNA?
Nucleotides are repeatedly joined together to form a strand of DNA. Each nucleotide consists of a phosphate group, a sugar molecule (deoxyribose), and a nitrogenous base (adenine, thymine, cytosine, or guanine).
Are nucleic acids polymers?
Both are made from smaller subunits that are joined by covalent bonds. In the case of proteins, these subunits are called amino acids. They are joined by special covalent bonds called peptide bonds. In the case of nucleic acids, the subunits are called nucleotides, which are a combination of a sugar (ribose or deoxyribose), phosphate group, and one of four possible bases (adenine, thymine, guanine, or cytosine). The nucleotides are covalently bonded along the "ladder" of the DNA molecule. Another feature of polymers is that the covalent bond that links the subunits (or monomers) is formed by dehydration synthesis, that is, a removal of a water molecule.
What joined by adjacent nucleotides?
The nucleotides are joined together by phosphodiester linkages between the sugar of one nucleotide and the phosphate of the next.
What are the nucleotides in DNA joined by?
peptide bonds
Are nucleotides joined together by covalent bonding of bases?
No, nucleotides are joined together by the formation of phosphodiester bonds between the phosphate group of one nucleotide and the sugar molecule of another nucleotide. The bases participate in hydrogen bonding interactions, not covalent bonding, within the DNA double helix structure.
What is the name of the structure formed when atoms are joined by a covalent bond?
The structure formed when atoms are joined by a covalent bond is called a molecule. In a covalent bond, atoms share electrons to achieve a stable electron configuration, resulting in the formation of a molecule with a specific chemical formula and properties.
What is the structure of a atom joined together with a covalent bonds called?
Molecule :)
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 are the monomers of DNA?
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".
What is the name of the linkage in nucleotides reaction?
The linkage in nucleotides is called a phosphodiester bond. It forms between the phosphate group at the 5' carbon of one nucleotide and the hydroxyl group at the 3' carbon of another nucleotide in a DNA or RNA molecule.
When two amino acids are chemically joined together the resulting structure is?
A polypeptide, and when several polypeptides are formed they link to form a protein.
How is a gene related to the sequence of nucleotides?
Genes are segments of DNA. DNA is made up of polymer of nucleotides joined together. When there is an alteration in the sequence of nucleotides, gene mutation occurs.
Name of substance that DNA is composed of?
DNA (deoxyribonucleic acid) is a double stranded polynucleotide. It is made of two anti-parallel strands of many individual units called nucleotides joined together. The nucleotides themselves consist of a phosphate group, a pentose sugar (in the nucleotides of DNA the pentose sugar present is deoxyribose) and a nitrogenous base (in the nucleotides of DNA the bases are adenine, thymine, guanine and cytosine).
Which compound is composed of many nucleotides?
DNA and RNA are composed of many nucleotides joined together in a specific sequence.
