Codons - Study guides, Class notes & Summaries

BIO 215 Rubenstien Final Exam UPDATED ACTUAL Exam Questions and CORRECT Answers osmosis - CORRECT ANSWER - Simple diffusion of water. Explain the 4 features of the genetic code - CORRECT ANSWER - 1) Degenerate: multiple codons code for one amino acid (reduces the harm of mutation) 2) Non-overlapping 3) Universal (nearly): almost all species follow the codon table

Chapter 15 Learn Smart set 7 1. release: In translation termination, stop codons are recognized by a protein known as a ___ factor. 2. They are coupled: In prokaryotes how do translation and transcription occur? 3. Transcription: Is the process during which an RNA copy of DNA is made. 4. initiation: Identify the state of transcription where the bacterial RNA polymerase is bound to the sigma factor causing it to bind to the promoter. After binding, RNA polymerase begins to unwind the DNA

Briefly explain how the base pairs A-T and C-G bond to each other and why the interactions they form are important to DNA unwinding. Base pairs form hydrogen bonds to each other. G and C form 3 hydrogen bonds, while A and T form 2 hydrogen bonds. These hydrogen bonds are weak electrostatic interactions that are able to hold the DNA together but are easily broken for the DNA to unwind. Why are telomerase inhibitors an attractive prospect for cancer therapies? >90% of cancer cells expres...

which of the following would NOT be found in a DNA sequence a) adenine b)guanine c)thymine d) uracil - ANSWER D A segment of pre-mRNA is cut up by spliceosomes so that 3 eons & 2 introns are formed. How many cuts were made on the pre-mRNA? a) 3 b) 4 c) 5 d) 6 - ANSWER B if a DNA strand contains the triplet nucleotides ATG-GCC-GCT, what would be the set of anti-codons that accompany the transcribed mRNA during translation?

What is the minimum number of nucleotides per amino acid required to specify all 20 amino acids? Correct Answer-3 nucleotide bases per amino acid Codon Correct Answer-a triplet of nucleotides that codes for a specific amino acid Translation occurs in such a way that these nucleotide triplets are read in a successive, nonoverlapping the key to the translation of genetic information, directing the synthesis of specific proteins Overlapping Correct Answer-AUACGAGUC -> is read like AU...

Variation: mutation - ANS mutation = any change in DNA point mutation - ANS point mutation = nucleotide substitution - substitution of one base type in a position for another base type types of mutations - ANS 1. point mutations 2. insertion 3. deletion 4. rearrangement 5. translocation --> a piece of DNA from one chromosome gets moved to another chromosome 6. synonymous mutation - a mutation has taken place, but there is no change in transcription of amino acids or t...
