I know somebody said the definition of dominant but if you are referring to a dominant gene (I assume so because the subjects says biology), then it is an allele that produces the same phenotype where its paired allele is identical or different.
Answer:
Scientists might replicate a strand of DNA using PCR before sequencing it. Once the sequence is known, they can produce a corresponding gene probe
Explanation:
PCR refers to the polymerase chain reaction that amplifies the small sample of DNA into multiple copies in three steps. These steps are denaturation of sample DNA to produce single-stranded template strand, binding of primer to the template and elongation. The multiple copies of the sample DNA are then used to decipher its sequence using various sequencing methods.
Once the sequence of the sample DNA is known, the short, single-stranded DNA molecules that are complementary to the specific sequence of DNA are formed. These single-stranded DNA molecules are called DNA probe and are used to detect the specific nucleotide sequence in some other sample DNA.
Because water keeps you hydrated and that's cool, but alcohol makes you drunk and that's not cool.
