BIO 1A03 McMaster University Test 2 Review UPDATED ACTUAL Exam Questions and CORRECT Answers Translation - CORRECT ANSWER- Cellular components are able to read the genetic message in mRNA and translate the message into specific primary amino acid sequence of a protein How does tRNA structure allow for SPECIFICTY in translation? - CORRECT ANSWER- 1. Plays critical role in ENABLING the translation of the information 2. Each type of tRNA molecule is not identical and can translate a spe...

one gene-one enzyme hypothesis - each gene contains the information needed to make an enzyme What did George Beadle and Edward Tatum research? - Relationship between genes and proteins using the Neurospora Crassa One gene-one enzyme hypothosis (Neuroposa Example) - Neurospora can grow well on minimal medium (simple sugar, vitamins, inorganic salts), and therefore it must have enzymes produced by a certain gene that that transform these materials into amino acids and vitamins needed for gro...

Binary Fission steps - -Initiated when proteins attach DNA to plasma membrane -Begins along ORI region -Newly synthesized DNA also anchored to membrane -Cell elongates until ~2 times its original size and two has two chromosomes on opposite ends of the cell -Cell splits in two Quiescent stem cells, function - Permanently arrested in G0 phase. In adults: can replace non-reproducing specialized cells) ex adult skeletal muscle/myofiber) Steps of quiescent stem cell to myofiber - -Activate...

Central Dogma - theory that states that, in cells, information only flows from DNA to RNA to proteins what enzyme is used to transcribe DNA and describe the process - RNA polymerase attaches to specific promoter regions its these promoter regions which identifies the starting point, describe the DNA and RNA directionality and how the direction followed by RNA polymerase - the 5' end has the 5'phosphate on a nucleotide the other end is the 3' OH group of a nucleotide -traditionally rea...
