multiple choice 10 points
which biotechnology technique is used to separate dna fragments based on size?
pcr
dna sequencing
crispr
gel electrophoresis

Explanation:

Gel electrophoresis is a technique used to separate DNA fragments based on their size. DNA fragments are loaded into wells in an agarose gel, and an electric current is applied. Smaller fragments move faster through the gel matrix than larger ones. CRISPR is a gene - editing tool. DNA sequencing determines the order of nucleotides in DNA. PCR (Polymerase Chain Reaction) is used to amplify DNA.

Answer:

Gel electrophoresis
