What is the DNA -> RNA process? - RNA polymerase I creates a transcript. This is primary RNA with 5' cap and 3' with poly(a) site. Maturation of RNA includes cleaving at the poly(a) site and RNA splicing of introns to leave matureRNA. What is the mRNA to protein process? - Codons run through ribosome in 3 base pairs. A corresponding tRNA recognises 3 base pair and brings with it conjugate bases and an AA. This adds the relevant AA for every 3 base pair, creating a polypeptide. What is...

Question 1. What is modern cell biology? - An integrated discipline that includes cell culture, microscopy, molecular biology, genetics, and biochemistry. Question 2. What is gene ontology? - A major bioinformatics initiative to unify the representation of gene and gene product (i.e. proteins and RNA) attributes. The project includes development of a controlled vocabulary of a protein's attributes. Question 3. What are the three domains of gene ontology? Briefly describe them. - Cellular ...
