ANSWER THE FOLLOWING QUESTIONS IN THE REQUIRED FORMAT LISTED BELOW THE QUESTION: Which of the following are considered part of a gene? (state all possible answers from below) Question 1 options: poly A tail promoter enhancer coding region 5′ and 3′ untranslated region stop codon exon intron TATA box 2. The following questions are based on the gene TTG2 from Arabidopsis, here is the site on NCBI: (you must use this site alone) http://www.ncbi.nlm.nih.gov/gene/818303 For these questions, the variants are labelled in the order they appear in the graphic view. Example: Variant 1 has the following IDs for mRNA and protein (NM_129282.4 & NP_181263.2), make sure that you follow the correct mRNA and protein for each variant as they may not appear in the expected order in NCBI. What is the length of the 3′ UTR for variant 2. Include only the number of nucleotides. Do not include a label such as “nucleotides”, “basepairs” etc. (type answer) 3. What is the length of the 5′ UTR for variant 2. Include only the number of nucleotides. Do not include a label such as “nucleotides”, “basepairs” etc. (type answer) 4. The last exon in all three variants is the same size. Question 4 options: True or False ? (choose one) 5. All variants have one exon that is exactly the same. Question 5 options: True or False ? (choose one) 6. All nucleotides of the gene that are not translated are the untranslated region. Question 6 options: True or False ? (choose one) 7. Nucleotides 1680 of variant 3 is an intron. Question 7 options: True or False ? (choose one) 8. What is the longest region that is identicalÂ between the mature mRNAs for the three variants? (you must type answer) 9. Which nucleotides of the gene are part of the coding sequence in only one variant? Use the same format NCBI uses: 1..10, 20..30, 40..50 (type answer) 10. What region of the variant 3 mRNA is unique? List the nucleotides in the NCBI format as in question 8. If no region is unique write ânoneâ. (type answer)
