Daly made significant contributions to the study of
Daly's subsequent studies went beyond molecular genetics to examine cardiovascular health, specifically the relationship between high blood pressure and cholesterol and arteriosclerosis, or the hardening of the arteries. Public health recommendations on nutrition and heart disease prevention were impacted by her research, which showed the link between diet and cardiovascular disease and clarified the effect of high-fat diets on heart disease.
Daly also worked to support initiatives that inspired minority students to seek careers in science and was dedicated to mentoring new scientists, especially those from underrepresented backgrounds. Generations of scientists are still motivated by her legacy as a researcher and educator, particularly women and people of color in STEM areas.

- Chemical analysis shows that a nucleic acid sample contains A, U, C, and G. Is this DNA or RNA? Why?arrow_forwardWhat percentage of the DNA in the genome actually corresponds to genes? How much is actually protein-coding exons? What makes up the rest?arrow_forwardHow many nucleotides does the human genome contain?arrow_forward
- Describe the structure and complementary base pairing of DNA.arrow_forwardDNA contains many hydrogen bonds. Are hydrogen bonds stronger or weaker than covalent bonds? What are the consequences of this difference in strength?arrow_forwardIf an extra nucleotide is inserted in the first exon of the beta globin gene, what effect will it have on the amino acid sequence of the globin polypeptides? Will the globin most likely be fully functional, partly functional, or nonfunctional? Why?arrow_forward
- Why is DNA replication called semiconservative?arrow_forwardBelow is a sequence of 540 bases from a genome. What information would you use to find the beginnings and ends of open reading frames? How many open reading frames can you find in this sequence? Which open reading frame is likely to represent a protein- coding sequence, and why? Which are probably not functioning protein-coding sequences, and why? Note: for simplicitys sake, analyze only this one strand of the DNA double helix, reading from left to right, so you will only be analyzing three of the six reading frames shown in Figure 19.4.arrow_forwardAlthough it is well known that X-rays cause mutations, they are routinely used to diagnose medical problems, including potential tumors, broken bones, and dental cavities. Why is this done? What precautions need to be taken?arrow_forward
