1) What is the central dogma of genetic information? A: Transcription of DNA to RNA to protein: This dogma forms the backbone of molecular biology and is represented by four major stages. 1. The DNA replicates its information in a process that involves many enzymes: replication. 2. The DNA codes for the production of messenger RNA (mRNA) during transcription. 3. In Eukaryotic cells, the mRNA is processed (essentially by splicing) and migrates from the nucleus to the cytoplasm. 4. Messenger RNA carries coded information to ribosomes. The ribosomes "read" this information and use it for protein synthesis. This process is called translation . 2) What dictates the three-dimensional structure of a protein?

Unformatted text preview: A: its amino acid sequence . 3) What is the genetic information present in DNA described by? A: the sequence of bases along a DNA strand. 4) List the key processes in a cell that can control the amount and level of activity of a protein. A: Transcription of DNA, splicing of RNA, mRNA degradation, mRNA translation, post-transcriptional modifications, protein degradation. 5) How does a relatively limited set of genes and process gives rise to an infinite set of biological processes? A: Each process allows variability in and of itself, and the combinatorial combination is what allows it...
