Denning [Date] [Course title]
, In Griffith's experiments, what made the harmless R cells grow capsules when exposed to heat-killed S
cells? - Correct Ans: DNA
In the Hershey-Chase experiment radioactive Sulfur was used to: - Correct Ans: Be incorporated into the
phage protein coat because some amino acids contain sulfur
The experiments by Hershey and Chase helped confirm that DNA was the hereditary material on the
basis of the finding that: - Correct Ans: Radioactive phosphorus was found inside the cell
If DNA of a particular species was analyzed and it was found that it contains 27 percent of adenine (A),
what would be the percentage of cytosine (C)? - Correct Ans: 23 percent
Your chromosomes are located _______ and they are made of ___________ . - Correct Ans: in the
nucleus, DNA
A nucleotide is made of _______. - Correct Ans: sugar + phosphate + nitrogen base
A molecule of RNA (ribonucleic acid) contains the bases _______. - Correct Ans: adenine, guanine,
cytosine, and uracil
Which of the following does cytosine pair with? - Correct Ans: Guanine
Prokaryotes contain a _________ chromosome, and eukaryotes contain ________ chromosomes. -
Correct Ans: double-stranded circular; double stranded linear
