Biology 198 Module 4 Exam Questions And Answers (Updated And Verified)

, thymine, guanine, and cytosine. The genetic information is the sequence of nucleotides in the DNA. What is the process of transcription? - answerTranscription is the process by which the information in a strand of DNA is copied into a new molecule of messenger RNA. This takes place in the nucleus. The genetic material serves as a template. Transcription is carried out by an enzyme called RNA polymerase and a number of accessory proteins called transcription factors. What is the process of translation? - answerTranslation is a step in protein biosynthesis where a genetic code from a strand of mRNA is decoded to produce a sequence of amino acids. A protein made up of amino acids is produced. The major cellular machinery is the ribosome and tRNA. Codons and anticodons which serve as templates for linking amino acids together. This takes place in the cytoplasm or endoplasmic reticulum. What is the universal genetic code? - answerThe universal genetic code is the set of DNA and RNA sequences that determine the amino acid sequences used in the synthesis of an organism's proteins. Which molecule contains codons? - answerMessenger RNA (mRNA) Which molecule contains anticodons? - answerTransfer RNA (tRNA) How do codons and anticodons interact? - answerThe messenger RNA reads the anticodon to make sure the amino acid goes to the right place. It is read from 3 to 5 but will be copied 5 to 3.
