SOUTHERN BLOTTING

SOUTHERN BLOTTING. The technique was developed by E.M. Southern in 1975. The Southern blot is used to detect the presence of a particular piece of DNA in a sample. The DNA detected can be a single gene, or it can be part of a larger piece of DNA such as a viral genome. SOUTHERN BLOTTING.

Transcription: From DNA to RNA

Transcription: From DNA to RNA. Chapter 8.2. Why RNA?. DNA cannot leave the nucleus BUT proteins are built by the ribosomes in the cytosol! We need a messenger to transfer the genetic code to the ribosomes mRNA is a complementary copy of a gene that CAN leave the nucleus. Messenger RNA.

PCR

PCR. By: Cody Alveraz Ted Dobbert Morgan Pettit . What is PCR?. PCR is a polymerase chain reaction that copies pieces of DNA across multiple orders of magnitude, creating thousands to millions of copies of DNA sequences. It was developed in 1983 by Kary Mullis.

Biology Warm Up: Transcription

Draw a double-stranded DNA molecule that has this nucleotide order on one strand: G T T A C A A T C G T T A C A A T C Use a D for deoxyribose and P for the phosphate groups. Be sure to correctly form the complimentary strand according to the rules of base pairing.
