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.
The nucleotide sequence of a gene consists of a specific order of nucleotides (adenine, thymine, cytosine, and guanine) that encodes the information for producing a particular protein. In contrast, an entirely different gene will have a distinct nucleotide sequence that may vary significantly in length, composition, and arrangement. While some genes may share similar sequences due to evolutionary relationships or functional similarities, others can be vastly different, reflecting their unique roles in the organism. Overall, the diversity in nucleotide sequences contributes to the vast array of functions and characteristics of different genes.
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.
Point Mutation- a type of gene mutation in which only a single nucleotide in a gene has been changed.
A mutation.
In the context of the BRCA-1 gene, if an A nucleotide is replaced with the nucleotide that normally pairs with cytosine (C), the nucleotide that is substituted is thymine (T). This is because adenine (A) pairs with thymine (T) in DNA, while cytosine (C) pairs with guanine (G). Therefore, the abbreviation for thymine is T.
A nucleotide consists of a base pair ( A with T, C with G) with a sugar phospate molecule
