Two strand of dna
WebWhen a molecule of DNA is double stranded, as DNA usually is, the two strands run in opposite directions. Therefore, one end of the molecule will have the 3' end of strand 1 and the 5' end of strand 2, and vice versa in the other end. However, the fact that the molecule is two stranded allows numerous different variations. Blunt ends WebThe CRISPR-Cas9 system consists of two key molecules that introduce a change into the DNA. These are: an enzyme called Cas9. This acts as a pair of ‘molecular scissors’ that can cut the two strands of DNA at a specific location in the genome so that bits of DNA can then be added or removed. a piece of RNA called guide RNA (gRNA).
