What is a function of an AUG codon other than to start a new protein-coding sequence?...
Indicate the amino acid sequence of the protein encoded by the following mRNA molecule. Use the genetic code table and assume that the very first “AUG” the ribosome encounters will serve as the start codon. 5’-AAUUCAUGCCCAAAUUUGGGGCACGAAGCUUCUUAGGCUAGUCCUAAAAAA-3’
1. How is the start codon identified in prokaryotic cells? a. It is the only AUG on the mRNA strand. b. It is the AUG after the Shine-Dalgarno sequence. c. It is the AUG right next to the promoter on the mRNA. d. It is the AUG after the Kozak sequence. e. It is the AUG nearest the 5' end of the mRNA. 2. All of the following are true for eukaryotic transcription EXCEPT: a. Transcription can be terminated when...
C++: Translating mRNA sequence help Homework Description Codon 1 You are working in a bioinformatics lab studying messenger RNA (mRNA) sequences. mRNA is a sequence of the nucleotide bases (Adenine, Cytosine, Guanine, and Uracil) that conveys information stored in DNA to Ribosomes for translation into proteins. The bases in the sequences are denoted by the first letters of the nucleotide bases (e.g. A, C, G, and U). A sequence of mRNA is made up of hundres to thousands of nucleotide...
Chapter 15: 1. What is the significance of the fact that many synonymous codons differ in the third nucleotide position? 2. Define the following terms as they apply to the genetic code: a. Reading frame b. Overlapping code C. Nonoverlapping code d. Initiation codon e. Termination codon f. Sense codon 8. Nonsense codon h. Universal code i. Nonuniversal code 3. What role do the initiation factors play in protein synthesis? 4. Compare and contrast the process of protein synthesis in...

QUESTION 7 If the MC1R protein is 317 amino acids long why are there 954 base pairs in the coding region of the gene? Each amino acid has a mRNA codon and DNA triplet consisting of a three-base sequence. (317 x 3951 plus a stop codon (951-3-954) to signal the end of translation) Because there are 317 proteins in the MC1R code. mutant proteins always have 954 base pairs. Each amino acid has a mRNA codon and DNA triplet consisting...
