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

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

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 )
