Biology 1000 – Principles of Biology ( BioS 115 Core II: Genetics) Exam Study Guide Questions With Answers. Explain the concepts of penetrance and expressivity Penetrance is the percentage of cases in which a certain phenotype is expressed. There are two types: i. Complete Penetrance: when 100% is correlated to the genotype. So, all express the same thing. ii. Incomplete: this is when some are identical, and others are different. Penetrance= # with genotype showing phenotype x 100 # wit...

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...

Chapter 13 Practice Exam 42 Questions with Verified Answers Which of the following is a type of RNA that gets translated? A) rRNA B) mRNA C) tRNA D) miRNA E) A, B, and C all get translated. - CORRECT ANSWER B Which of the following RNA molecules are required for the process of translation? A) crRNA B) tRNA C) snRNA D) snoRNA E) siRNA - CORRECT ANSWER B Over time, DNA replaced RNA as the primary carrier of genetic information, and the chemical stability of DNA is believed to be...

Describe the process of transcription. What are the starting molecules and the end products? - Transcription is the manufacture of a strand of RNA complementary to a strand of DNA. In initiation, RNA polymerase binds to a promoter region on the DNA strand. RNA synthesis occurs during the elongation phase as RNA nucleotides are added to the growing RNA polynucleotide. When the RNA polymerase reaches the terminator region of the gene, elongation stops and the polymerase and new RNA molecule d...
