Four bands appear in gel electrophoresis. Gel electrophoresis is an experimental method used to separate mixtures of DNA, RNA, or proteins by molecular size.
DNA is negatively charged, so when a current is applied to the gel, the DNA migrates towards the positively charged electrode. Fragments are ordered by size because short DNA strands migrate through the gel faster than long strands. There are some basic steps for performing gel electrophoresis outlined below. 1) pour the gel, 2) prepare the sample, 3) load the gel, 4) run the gel (expose it to an electric field), 5) stain the gel. Gel electrophoresis is a technique for separating biomolecules by size. Separation of these molecules is achieved by placing them in a small pore gel and creating an electric field across the gel

#SPJ4
Answer: A because two of the same pairs are homologous
Answer:
A. acquired traits can be passed to offspring.
Explanation:
Mendel tracked the segregation of parental genes and their appearance in the offspring as dominant or recessive traits.
The correct answer should be The ability to reproduce only within a species.
Physical chemists study matter and energy, and there is chemical reactions in your body, and all living things have elements, like carbon.
I would say D
