Purine nucleotides differ from pyrimidine nucleotides in their structure due to the number of nitrogen-containing rings they have. Purine nucleotides have a double-ring structure, while pyrimidine nucleotides have a single-ring structure.
To calculate the number of nucleotides required to code for a specific polypeptide, you need to know the number of amino acids in the polypeptide. Since each amino acid is coded by a codon made up of three nucleotides, you would need 3 times the number of amino acids to determine the total number of nucleotides required. For a 150 amino acid polypeptide, the number of nucleotides would be 150 (amino acids) * 3 (nucleotides per amino acid) = 450 nucleotides.
The number of nucleotides in a DNA sequence can vary, but in general, a human DNA molecule contains about 3 billion nucleotides.
DNA, mRNA, and tRNA
The number of nucleotides in an mRNA is directly related to the number of amino acids in the resulting protein. Since each amino acid is coded for by a sequence of 3 nucleotides (codon), the number of amino acids is determined by dividing the total number of nucleotides (336) by 3. Therefore, a mRNA of 336 nucleotides will translate to a protein with 112 amino acids.
Three nucleotides are required for an amino acid. These nucleotides are an amine, carbolic acid, and a side chain specific to the amino acid.
The number of codons needed to code for a protein varies depending on the length of the protein. Each amino acid is coded for by a specific sequence of three nucleotides (a codon). Therefore, you would need to divide the total number of nucleotides in the protein's gene sequence by 3 to find the number of codons required.
The number of base pairs formed by 8 DNA nucleotides is 8.
RNA is composed of a single strand of nucleotides, which are typically represented by the letters A, U, G, and C. Therefore, RNA consists of one chain of nucleotides.

Yes, please.
The minimum number of nucleotides on mRNA to code for a protein of 100 amino acids is 300. This is because each amino acid is coded for by a sequence of three nucleotides called a codon. So, 100 amino acids x 3 nucleotides per codon = 300 nucleotides.
