- Let’s return to your patient with sickle cell anemia. Below is the RNA sequence from your patient and from her mother. (The ••• represents another 30 nucleotides not written out here). The affected nucleotide is indicated in BOLD. Patient’s RNA: 5’ –CUAUGACAGAGUUC•••CAUUAGCCA – 3’ Mother’s RNA: 5’ –CUAUGACAGUGUUC•••CAUUAGCCA – 3’ A) Write out the first 10 nucleotides corresponding to the DNA sequence of the coding strand for your patient in the 5' to 3' direction. B) From the information you have been given, why is it not possible to accurately write out the DNA sequence as it would really be found in the genome? (ie, what you wrote down in part A is NOT necessarily what the DNA sequence would really look like if we could examine the chromosome directly - why? And no this has nothing to do with the 30 nucleotides that aren’t written out or the mutated base). Your answer should be 1-2 sentences maximum.Which of the following are TRUE for RNA compared to DNA? Please select ALL correct answer options. Select 4 correct answer(s) Question 6 options: RNA contains the bases A, G, C, and U, whereas DNA contain the bases A, G, C, and T. RNA can catalyze biological reactions, but DNA cannot. DNA but not RNA can bind proteins RNA has ribose sugar in its nucleotides, rather than the deoxyribose found in DNA. RNA is usually single stranded and can make more complex three-dimensional molecular shapes than double-stranded DNA.Select the incorrect statement w.r.t. double helical structure of DNA. 1. The two chains of DNA run in anti-parallel fashion 2. The backbone is constituted by sugar-phosphate 3. The nitrogenous bases project outwards 4. Guanine is bonded with cytosine with three H-bonds

A. point mutation B. movement of large section of chromosome C. duplication of entire chromosome D. genetic recombination 2. Will this mutation have a real effect? Why or why not?DNA STRAND IS 3’ TAC-AGC-ACT-CAG-TCA 5’, whats the non-template/sense/coding strand from the STARND DNA? also what's the arrangement of m-RNA and the chain arrangement of the amino acids that will be made according to the order of the RNA?PLS DONT ANSWER THE DEFINITION ONLY, READ THE QUESTION CAREFULLYPlease choose the correct answer. Given the sense strand of DNA, A T G T A A C C G C G C A A G G G C A T G T G A, how many amino acids are in the protein coded by this piece of DNA? a. five b. six c. seven d. eight
