Which example of genetic variation is a variant of a gene?
One example of genetic variation that is a variant of a gene is a single nucleotide polymorphism (SNP), which is a change in a single DNA building block within a gene.
What are the differences between SNP and allele in terms of genetic variations?
SNP (Single Nucleotide Polymorphism) is a specific type of genetic variation that involves a single nucleotide change in the DNA sequence. An allele, on the other hand, refers to different versions of a gene that can result in variations in traits. In summary, SNPs are a type of genetic variation at the nucleotide level, while alleles are variations of genes that can influence traits.
What is the significance of a SNP, one of about 10 million known places in the human genome?
A SNP, or single nucleotide polymorphism, is a variation in a single DNA building block that can affect traits and disease risk. They are significant because they can help researchers understand genetic differences between individuals and their impact on health and disease.
What is the difference between an allele and a SNP?
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.
Which mutation occurs when one nucleotide is replaced with another base?
Substitution
How can one detect polymorphism by genetic marker?
One can detect polymorphism by genetic marker using single-nucleotide polymorphism which is able to even tell mutation of a gene.
What is a SNP?
A SNP (Single Nucleotide Polymorphism) is a variation at a single position in a DNA sequence that occurs when a single nucleotide (A, T, C, or G) differs between individuals. SNPs are the most common type of genetic variation in individuals and are used in genetic studies to understand genetic predispositions to diseases and traits.
Which example of genetic variation is a variant of a gene?
One example of genetic variation that is a variant of a gene is a single nucleotide polymorphism (SNP), which is a change in a single DNA building block within a gene.
What is the dbSNP most known for?
The dbSNP is a database archive of genetic materials records which may be accessed freely. It holds genetic information across species. "dbSNP" stands for the Single Nucleotide Polymorphism Database.

A variant in a DNA sequence that occurs in at least 1 percent of the population is called?
A variant in a DNA sequence that occurs in at least 1 percent of the population is called a single nucleotide polymorphism (SNP). SNPs are common genetic variations that can be used in genetic studies to understand disease susceptibility, drug response, and other traits.
What is a non synonymous polymorphism?
Substitutions that result in amino acid replacements are said to be nonsynonymous while substitutions that do not cause an amino acid replacement (such as a GGG to GGC change - both codons still encode glycine) are said to be synonymous substitutions
How is a SNP identified in an alignment?
A SNP (Single Nucleotide Polymorphism) is identified in an alignment by comparing the DNA sequences of different individuals or species. A SNP is a variation at a single nucleotide position in the DNA sequence. By aligning the sequences and looking for differences at specific positions, researchers can identify SNPs.
What is the definition of SNP genotyping?
The definition of SNP genotyping is the measurement of the genetic variation between members of a species. Single nucleotide polymorphisms (SNP) are one of the most common types of genetic variation.
