Suppose two suspects in a crime scene have dna profiles that match the one dna fragment tested. what should happen next?

1. monkey

2. the sample yields very little DNA, which means that it must be amplified to produce enough quantity to detect on a gel

3.the sample taken from the crime scene should be analyzed for multiple DNA fragments .

4. all of the suspects can be ruled out

label a cell membrane

label b cytoplasm

label c ribosomes

label d dna

the membrane forms the outside of the cell

cytoplasm is the liquid within

ribosomes are the components within that distribute rna

the dna is the genetic make-up

the correct answer is 4) heat and pressure

metamorphic rocks arise from transformation of existing rocks types, in a process called metamorphism. during metamorphism the original rock(prolith) change into metamorphic rock by heating (150-200c) and pressure of more than 1000 bar. the original rock can be sedimentary, igneous, or existing metamorphic rock.
