Textbook Question
Chapter 21.2, Problem 3CC
MAKE CONNECTIONS Ø The ENCODE pilot project found that at least 75% of the genome is transcribed into RNAs, far more than could be accounted for by proteiri-coding genes. Review Concepts 17.3 and 18.3 and suggest some roles that these RNAs might play.

Mutations in the stem loop around the coat gene initiation codon that weakens the base-pairing in the stem loop. c.

You revealed that homozygous mutation in the SLB gene is the main cause of paralysis. The following sequence of SLB gene at the beginning of the translated region is found in individuals without paralysis. 5‟-GTA GCA TTT AAG CTT CAG TCC AAG - 3‟ (Met Thr Phe Glu Ile Gln Ser Arg). This sequence is however changed to the following sequence in affected individuals 5‟- GTA GCA TTT AAG CTT TAG TCC AAG - 3‟ (Met Thr Phe Glu Ile STOP). What mutation you will identify from this observation? Explain with reason. After identifying mutation if there is any, enlist all the possible repair mechanisms that can be helpful to repair the current situation. Elaborate your answer with that why you think that your suggested repair pathway should be used and how it can be effective for repairing in the current scenario?arrow_forward
