Which ingredients/molecules are required to set up a polymerase chain reaction? Correct Answer DNA polymerase, DNA nucleotides, template DNA, DNA primers
Assuming 100% reaction efficiency, how many DNA copies will be produced after 5 PCR cycles, if we begin with 1 DNA template Correct Answer 32
The LEP gene codes for an anorexigenic hormone. Interestingly, breastfeeding has been shown to alter methylation of the promoter of this gene, leading to increased LEP expression. What is likely happening in response to breastfeeding? Correct Answer Breastfeeding decreases the methylation of the promoter of the LEP gene, increasing the spacing between nucleosomes
Rett syndrome is a brain disorder that occurs almost exclusively in females, causing severe deficits in language, learning, coordination and other brain functions. Decreased expression of the MECP2 gene causes Rett syndrome. Which of the following scenarios correctly describes how Rett syndrome could be developed? Correct Answer transcription factors are unable to bind to the transcription start site of the MECP2 gene because the nucleosomes are tightly packed together
What happens when the incorrect base is added during the synthesis of a DNA strand in DNA replication? Correct Answer DNA polymerase removes the incorrect base and adds in the correct base (mismatch repair during replication)
A patient with Xeroderma pigmentosum is prone to developing multiple skin cancers starting in childhood. This occurs because of a mutation in a gene that codes for enzymes that help repair DNA damage through the nucleotide excision repair (NER) pathways. How does NER differ from other repair mechanisms? In NER: Correct Answer the error in one strand of DNA is removed as well as several nucleotides on either side of the error. the gap that was removed is filled by DNA polymerase
