Copula (linguistics) In linguistics, a copula (plural: copulas or copulae; abbreviated cop) is a word used to link the subject of a sentence with a predicate (a subject complement), such as the word is in the sentence The sky is blue.. The word copula derives from the Latin noun for a link or tie that connects two different things.
Scientists study DNA for many reasons: They can figure out how the instructions stored in DNA help your body to function properly. They can use DNA to make new medicines or genetically modify crops to be resistant to insects. They can solve who is a suspect of a crime, and can even use ancient DNA to reconstruct evolutionary histories! To get the DNA from a cell, scientists typically rely on one of many DNA extraction kits available from biotechnology companies. During a DNA extraction, a detergent will cause the cell to pop open, or lyse, so that the DNA is released into solution. Then alcohol added to the solution causes the DNA to precipitate out. In this activity, strawberries will be used because each strawberry cell has eight copies of the genome, giving them a lot of DNA per cell.
