19

a feature of organic compounds NOT found in inorganic compounds is the prescence

carbon atoms covalently bonded to each other

Bacteriophages are viruses that infect bacteria. In an experiment, bacteriophages were labeled with either radioactive phosphorus or radioactive sulfur. The labeled bacteriophages were incubated with bacteria for a brief amount of time the removed. The infected bacteria cells were found to contain significant amounts of radioactive phosphorus but not radioactive sulfur. Based on the results of the experiments, which of the following types of molecules did the bacteriophages most likely inject into the bacteria walls?

dna

a molecule with the chemical formula C6H12O6 is probably a _________

monosaccharide

The secondary compund cyanide (chemical formula HCN) is a toxic, bitter-tasting chemical that is found in apple seeds. Cyanide in seeds is only released and tasted if the seed is crushed. When animals eat apples, they typically eat the sweet fleshy part of the fruit and spit out the seeds or swallow them whole. Based on the chemical formula cyanide, which biological macromolecule could serve as a chemical precursor for the production of cyanide in a plant?

nucleic acids

use the following figure to answer the question

results in a peptide bond

A student analyzed a viral genome and found that the genome had the following nucleotide composition: 28% adenine, 20% thymine, 35% cytosine, 17% guanine. Which of the following best describes the structure of the viral genome?

single-stranded dna

which of the following characteristics of figure 1 best shows that the fragment is RNA and not DNA
