These sticky ends will stick (or anneal) to another piece of DNA by complementary base pairing,but only if they have both been cut with the same restriction enzyme. Restriction enzymes are highlyspecific, and will only cut DNA at specific base sequences, 4-8 base pairs long, called ...
Describe the structure and complementary base pairing of DNA. Explain how single nucleotide changes can have vastly different effects on protein function. How do the proteins of the transcription machinery access DNA that is tightly associated in chromatin? How does the cell use the info...
Hydrogen bonds between complementary nucleotides maintain the structure of double-stranded DNA since they hold the two strands together. Why couldn't the two strands be effectively linked by covalent bonds? What is the double helix model of DNA? In molecules of...
