These are 20 MC questions

1. The human genome consists of approximately base pairs of DNA. A. 100,000 B. 1 million C. 1 billion D. 3 billion E. 2 trillion hnRNA AUG UAG AAUAAA molecule 2. What is the most likely consequence of a mutation at the position indicated by the arrow in the above schematic of an hnRNA molecule? A. None; this region has no possible function B. Aberrant splicing of the RNA C. Altered response to regulatory factors D. The mRNA would be improperly capped E. The mRNA would be unstable and prone to degradation Use the scenario below to answer the next 5 questions The DNA sequence preceding the gene encoding ovalbumin contains an estrogen responsive element which is bound by the estradiol:estrogen receptor complex to promote recruitment ofTFII-D. 3. This is an example of what level of gene regulation? A. Transcriptional B. RNA stability/turnover C. Translational D. Post-translational E. Chromatin packing 4. The estrogen responsive element would be classified as what kind of signal? A. core promoter element B. operator C. silencer D. enhancer E. TATA box

Explanation / Answer

1.Human genome consist of approximately 3 billion base pairs of DNA. It means 6 billion base pair per diploid cell.

2.The mRNA would be improperly capped is the most likely consequences of a mutation at the position indicated by the arrow in the above schematic of an hnRNA molecule.
