NURS 6630 week 2 Discussion Questions With Answers: Foundational Neuroscience. Epigenetics focuses on alterations and modification of genes, including methylation, acetylation, phosphorylation, and ubiquitylation of DNA and histone proteins (nucleosomes), and chromatin remodeling results in disorders like cancer and degenerative diseases (Rasool et al., 2015). Rasool et al. noted that factors like nutrition and the environment cause epigenetics alteration. The authors proposed that the coll...

BIOL 3030 Practice Exam 40 Questions with Verified Answers Which enzyme untwists the parent strands of DNA during replication? - CORRECT ANSWER DNA helicase Tetrad analysis is a technique for a. determining base sequences in DNA b. mapping genes in organisms retaining the four meiotic products in one structure c. measuring the number of chromatids at meiosis d. separating neurospora mycelia - CORRECT ANSWER b. mapping genes in organisms retaining the four meiotic products in one struct...

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? - Breastfeeding decreases the methylation of the promoter of the LEP gene, increasing the spacing between nucleosomes. A patient with xeroderma pigmentosum is prone to developing multiple skin cancers starting in childhood. This occurs because of a mutation in...

Which level of protein structure is disrupted through the hydrolysis of peptide bonds? Quaternary Tertiary Primary Secondary - ANSWER Primary The primary structure of a protein is the sequence of amino acids held together by peptide bonds. Peptide bonds are formed by dehydration reactions and disrupted by hydrolysis. A mutation in the beta-hemoglobin gene, which results in the replacement of the amino acid glutamate in position 6 with the amino acid valine, leads to the develop...
