The wobble hypothesis involves __________. tRNA mRNA rRNA both mRNA and rRNA both mRNA and tRNA Question 3 Areas of a eukaryotic gene that are represented in the final protein product are termed __________. introns mutons recons exons cistrons End of Question 3 Question 4 4 Enhancer elements are found __________. in none of the stated regions; enhancers are environmental agents in any of these regions within coding sequences downstream from the start site upstream from the start site End of Question 4 Question 5 5 Regarding enhancers and transcription factors (TFs) and their effects on gene expression, __________. both are trans-activating enhancers are cis-activating, while TFs are trans-activating enhancers are trans-activating, while TFs are cis-activating both are cis-activating neither are cis- or trans-activating; they are repressors End of Question 5 Question 6 6 frameshift mutations anticodons start and stop codons RNA homopolymers universality of the genetic code End of Question 6 Question 7 Which of the following does NOT involve introns? alternative splicing ribozymes intervening sequences heteroduplexes antisense oligonucleotides End of Question 7 Question 8 8The genetic code is considered "degenerate" because __________. the code originated from bacterial genomes DNA is unstable Degenerate is the name of the person who deciphered the code more than one nucleotide triplet codes for the same amino acid End of Question 8

Wobble: tRNA 3.Exons 4.Within coding sequences? 5/7 don't know will read up and be back. 6.What is the question again? 8.More than one nucleotide triplet codes for the same amino acid.

1. tRNA 2. exons 3. enchancers can be located upstream, downstream from gene being translated and may be near the gene or thousand of the base pairs away. 4.promoters, enchansers,responce elements are binding sites for proteins are "CIS" regulators. Transcription factors are-"TRANS" regulators. 6. Where is the question???? 7. alternative splicing, but not sure 8.degenerate is the name of person.......ext.

Which of the following does NOT happen during hnRNA processing? A 7-methylguanosine cap is added to the 5' end of the RNA. A poly A tail is added. Exons are spliced together. Ribosomes bind and begin translation. Introns are spliced out.

Ribosomes bind and begin translation, procedure is going to be on mRNA ( in the cytoplasm) AFTER hnRNA finishes it's job ( splicing by spliceosome in the nucleus )
