The bases are adenine, thymine, cytosine, and guanine. They are only found in DNA.

Gene is a collection of DNA which is made up of nucleotides.
Yes, a typical gene consists of regulatory sites in a promoter region that determine when and how much the gene is transcribed. The nucleotide sequence that is transcribed is called the coding sequence, which contains the instructions for making a specific protein or RNA molecule. All these elements work together to regulate gene expression.

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.
Point Mutation- a type of gene mutation in which only a single nucleotide in a gene has been changed.
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.
A mutation.
A nucleotide consists of a base pair ( A with T, C with G) with a sugar phospate molecule
A nucleotide consists of a phosphate molecule, a deoxyribose sugar, and a base (adenine, cytosine, gaunine, and thymine).
An allele is a specific form of a gene, while a SNP (Single Nucleotide Polymorphism) is a variation in a single nucleotide within a gene. In other words, alleles are different versions of a gene, while SNPs are specific points of genetic variation within a gene.
