No nucleotides are not proteins. Nucleotides are composed of nucleosides that are linked to phosphate groups and are the subunits of DNA and RNA.
proteins can be considered to be polymer of amino acids
G-proteins use phosphorilation of GDP into GTP (similar to ATP, but with guanine instead of adenine) to be activated.
During protein synthesis, the nucleotide sequence specifies a particular species of amino acid. This is accomplished through the genetic code, where a sequence of three nucleotides (codon) corresponds to a specific amino acid. The sequence of codons ultimately determines the sequence of amino acids in a protein.

Hi Genetic information can be obtained at different levels namely genomic DNA, RNA and protein.. another level, CDS (Coding sequence;actually part of mRNA) can be sometimes more informative than all above in the way that being 'inframe' DNA (more correctly cDNA) it can be directly converted to protein.. Such sequences can be obtained from of protein msa converted into nucleotide msa. This job cannot be done the usual way and requires aligned protein msa to be reverse translated to nucleotide msa (unaligned CDS is necessary to account for genetic redundancy and aligned protein msa is needed to preserve codon integrity and prevent alignment artefact ;gaps should be multiples of 3). Such sequences are often studied in context of molecular evolution e.g estimating nonsynonymous and synonymous substitutions in branches of phylogenetic tree.. HTH Cheers, Sunil

No, a gene is larger than a nucleotide. A gene is a segment of DNA that contains instructions for making a specific protein, while a nucleotide is a building block of DNA that makes up genes.
RNA uses uracil instead of thymine in its nucleotide sequence because uracil is more stable and efficient for the rapid synthesis of proteins during protein synthesis. Thymine is typically found in DNA, while uracil is specific to RNA.

A substitution mutation is a type of genetic mutation where one nucleotide in the DNA sequence is replaced with a different nucleotide. This can lead to changes in the amino acid sequence during protein synthesis, potentially altering the function of the protein. The impact of a substitution mutation on the genetic code depends on where it occurs and what specific nucleotide is substituted.
In a substitution mutation, a single nucleotide in the DNA sequence is replaced with a different nucleotide. This can change the amino acid that is coded for, potentially altering the protein that is produced. This can lead to changes in the genetic code, which may result in a different protein being produced or a non-functional protein.
The sequence of subunits in a protein is most directly dependent on the sequence of nucleotides in the gene encoding that protein. The nucleotide sequence dictates the amino acid sequence through the genetic code, and the amino acid sequence determines the protein's structure and function. Any changes in the nucleotide sequence can lead to alterations in the protein's composition and potentially its function.

The sequence of amino acids in a protein is determined by the sequence of nucleotides in the mRNA, and this is determined by the sequence of nucleotide bases in the DNA.
