Could Hershey and Chase have used a radioactive isotope of carbon instead of 32P Why or why not?

Could Hershey and Chase have used a radioactive isotope of carbon instead of 32P? No, because carbon is found in both DNA and protein. The sugar of RNA has a hydroxyl group that is not found in the sugar of DNA.

What is the Hyperchromic effect quizlet?

What is the hyperchromic effect? A hyperchromic effect is the increased absorption of UV light as double-stranded DNA is converted to single-stranded DNA.

What are the six bases on the complementary section of the other strand of DNA?

These bases are adenine (A), thymine (T), guanine (G) and cytosine (C). These nucleotides come together to form long chains known as DNA strands. Two complementary DNA strands bond to each other in what looks like a ladder before winding into the double helix form.

What observations are consistent with the conclusion that DNA serves as the genetic material in eukaryotes?

DNA is shown to be present in mitochondria, chloroplasts and nucleus, where genetic function is performed DNA is found to be the only macromolecule in eukaryotes that has different subunits. For DNA, content in various cell types action and absorption spectra of ultraviolet light are correlated.

How did Griffith prove that DNA is the genetic material?

Conclusion: Based on the observation, Griffith concluded that R strain bacteria had been transformed by S strain bacteria. The R strain inherited some ‘transforming principle’ from the heat-killed S strain bacteria which made them virulent. And he assumed this transforming principle as genetic material.

What enzyme makes it less likely that DNA will be lost from telomeres?

Telomerase

What happened Griffith injected mice?

What happened when Griffith injected mice with a mixture of heat-killed, pneumonia- causing bacteria and live bacteria of the harmless type? The mice got pneumonia and many died. He used enzymes that destroyed various molecules from the heat-killed bacteria, including lipids, proteins, carbohydrates, and RNA.

What happened when Griffith injected mice with the harmless?

When Griffith injected mice with disease-causing bacteria, the mice developed pneumonia and died. When he injected mice with harmless bacteria, the mice stayed healthy. Perhaps the S-strain bacteria produced a toxin that made the mice sick?

Why did Griffith need to show that the heat-killed bacteria didn’t make the mouse die?

2. Why did Griffith need to show that the heat-killed bacteria didn’t make the mouse die? Because the heat-killed bacteria mixed with the rough bacteria were lethal to the mouse, Griffith concluded that something from the heat-killed bacteria “transformed” the rough bacteria and made them lethal.

What happened when Griffith injected healthy mice with the smooth heat treated bacteria mixed with the rough bacteria?

In Griffith’s next experiment, he mixed the heat-killed, S-strain bacteria with live, harmless bacteria from the R strain and injected the mixture into laboratory mice. The injected mice developed pneumonia, and many died. The lungs of these mice were filled with the disease-causing bacteria.

What happened when Griffith mixed harmless living R bacteria with harmless heat-killed S bacteria and then injected mice with this mixture?

Experiment 4: Griffith mixed his heat-killed, disease-causing bacteria with live, harmless bacteria and injected the mixture into the mice. The mice developed pneumonia and died. Griffith concluded that the heat-killed bacteria passed their disease-causing ability to the harmless strain.
