Question

scientists perform dna sequencing to
multiple choice
determine the rna that is being expressed
determine the nucleotide order in a piece of dna
change the nucleotide order in a piece of dna
amplify the amount of dna in a sample

Explanation:

DNA sequencing is a technique to figure out the precise order of nucleotides within a DNA molecule. It doesn't directly determine expressed RNA, change the DNA nucleotide order, or amplify DNA amount.

Answer:

B. determine the nucleotide order in a piece of DNA
