A science researcher has developed a computer model of the process of DNA replication in a eukaryotic cell. The model includes the following sequence of bases in one strand of the DNA molecule. The researcher wants to revise the model to show the transcription of DNA to form mRNA. Which of these revisions to the model would be most useful for the researcher to include?

allowed for the prediction of the properties of missing elements.

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.
