QBM Final Exam Questions And Answers With Complete Solutions 2024 Define recombinant DNA technology Using molecular biology technique such as cloning, PCR, restriction enzymes digestion, and gel electrophoresis to take a gene from one source and joint it with another piece of DNA, creating a new recombinant DNA molecule that can be inserted in bacteria and further studied. What are 3 characteristics of DNA ? - Double strand - 5' to 3' directionality - antiparallel - base pairing [ad...

CHEMISTRY A LEVEL WITH SATISFIED SOLUTIONS What are the two elements which are exceptions to the electron configuration? - CORRECT-The two exceptions for this is copper and chromium. In both cases, the 4s subshell contains only one electron, even though there are electrons in the 3d subshell. To explain this, its because the 3d subshell is more stable when it is either half full, or completely full. So in the case of chromium, by having only one electron in the 4s subshell, ...
