What element is found in both nucleic acids and proteins?
Nitrogen is found in both nucleic acids (DNA, RNA) and proteins. In nucleic acids, nitrogen is present in the nitrogenous bases (adenine, guanine, cytosine, thymine, and uracil). In proteins, nitrogen is found in the amino groups of amino acids, which are the building blocks of proteins.
What macromolecule have nitrogen?
Proteins and nucleic acids contain nitrogen.Proteins use nitrogen as part of amino group, which is NH2.Nucleic acids use nitrogen for nitrogen bases such as adenine, guanine, cytosine, and thymine.
What molecules store nitrogen in the body?
In the body, nitrogen is stored primarily in the form of amino acids, which are the building blocks of proteins. Proteins are essential for various physiological processes and nitrogen is a crucial component of amino acids. Additionally, nitrogen can also be stored in other molecules like nucleic acids, which are composed of nitrogen-containing bases such as adenine, guanine, cytosine, and thymine.
How can 4 nitrogen bases code for thousands of proteins?
The genetic code is degenerate, meaning that multiple codons (sequences of 3 nitrogen bases) can code for the same amino acid. This redundancy allows for 4 nitrogen bases to encode for 20 different amino acids. By combining these amino acids in various sequences, thousands of different proteins can be synthesized.
How is the nitrogen base sequence of a gene related to the structure of a protein?
The sequence of nitrogenous bases (A, T, G and C) forms a code for the sequence of amino acids in a protein. The code is a triplet code. This means that three bases code for one amino acid. So, the order of the bases in a gene determines the order of the amino acids in a protein.

How many amino acids can a sequence of 24 DNA bases bases code for?

Which structure determines the sequence of the building blocks in a protein?
DNA determines the sequence of the amino acids (building blocks) in a protein. The sequence of nitrogen bases in the DNA determines the sequence of amino acids in a protein.
How do the nitrogen bases along a gene serve as a genetic code?
Nitrogen bases along a gene form codons, which are three-base sequences that code for specific amino acids during protein synthesis. This sequence of codons provides the genetic instructions that determine the sequence of amino acids in a protein. The genetic code is universal, meaning that the same codons code for the same amino acids in nearly all organisms.
Which contain nitrogen in addition to carbon oxygen and hydrogen?
Molecules that contain nitrogen in addition to carbon, oxygen, and hydrogen include amino acids, nucleic acids (DNA and RNA), and various nitrogen-containing bases and neurotransmitters.
How nitrogenous bases code for amino acids?
Nitrogenous bases in mRNA (adenine, cytosine, guanine, and uracil) form codons (three-base sequences) that code for specific amino acids during protein synthesis. Each codon corresponds to a specific amino acid, allowing for the translation of genetic information from nucleic acids to proteins through the genetic code.
Do polypeptide bonds hold nitrogen bases together?
The nitrogen bases, adenine, uracil, guanine, thymine and cytosine are joined to each other via phosphodiester bonds. Hydrogen bonds hold the nitrogen bases in complementary DNA and RNA strands. Polypeptide bonds are formed between an amide and ketone, and these join amino acids in proteins. However, they do not hold nitrogen bases together.
What is the source of the phosphate and nitrogen bases?
Phosphate groups come from ATP or other nucleotide sources, while nitrogen bases are derived from amino acids and other metabolic pathways. Both are essential components for building nucleic acids like DNA and RNA in living organisms.
What is the sequence of bases in DNA that codes for a single amino acid?
A sequence of three adjacent bases in DNA, called a codon, codes for a single amino acid. There are 64 possible codons, each specifying one of the 20 amino acids or serving as a signal to start or stop protein synthesis.
