Regarding behavioral therapy which of the following statements is FALSE In systematic desensitization the goal is to use relaxation as an incompatible response to fear in order to weaken the bonds between the frightening st and the fear response Behavior therapy is also referred to as behavior modification Since behavior therapy is focused on directly changing problem behaviors it tends to be relatively brief compared to other forms of therapy Aversive conditioning uses principles of operant conditioning to help people extinguish undesirable behaviors Gradual exposure can help people overcome specific phobias social phobias and post traumatic stress disorder

If the genetic code were comprised from staggered overlapping codons how many complete codons would the following sequence encode before encountering a stop codon 5 AUGCGAUUAUAAGUGC 3 O 4 10 15 06

The sequence between two potential stop codons is an open reading frame ORF Upon closer examination of the RNA sequence from the previous questions you determine the presence of an ORF that may encode for a putative protein which is 600 amino acid residues long How long is the ORF Open reading frame a stretch of DNA or RNA which is uninterrupted by a stop codon and may therefore encode for a protein Questions How many times do we need to tell you to stop 1 through 5 27 bases 83 bases 2 500 bases 600 bases 1 800 bases 259 bases 200 bases

What may be the ramifications of your analyses of the RNA you isolated It is clearly containing an ORF which is longer than what you expected to find based on the sequence analysis you have conducted What would be a logical conclusions based on the comparison of the lengths of the actual and predicted ORFs Questions How many times do we need to tell you to stop 1 through 6 Nature is random and your results using the Bard s words may be full of sound and fury but are really signifying nothing The difference between the actual and predicted sizes of the ORF is rather big and may suggest that the sequence of the RNA may not be as random as it first appeared This raises the hypothesis that what started as piece of junk RNA may be actually encoding for a protein The difference between the actual and predicted sizes of the ORF is not big enough to be significant and therefore your initial hypothesis that sequence is random is clearly random is supported
