Concept explainers
Interpretation:
The genetic material of viruses is to be stated.
Concept introduction:
Deoxyribonucleic acid is made up of two chains that form a double helix structure. DNA is used in the development, growth, reproduction, and functioning of a living organism.
Ribonucleic acid is a
Answer to Problem 1RE
Solution: Some viruses contain DNA and some viruses contain RNA and, in a few cases, the viral genome is single-stranded.
Explanation of Solution
Viruses are nanoparticles, which are made up of
DNA and RNA are the core of the genetic material of viruses and, in some cases, the nucleic acid of the virus is single stranded or double stranded.

- REFLECT AND APPLY Some viruses can undergo lysis or lysogeny even in the same host. What might be a reason for this? Under what conditions might the virus favor the one strategy over the other?arrow_forwardREFLECT AND APPLY E. coli incorporates deoxyribonucleotides into DNA at a rate of 250 to 1000 bases per second. Using the higher value, translate this into typing speed in words per minute. (Assume five characters per word, using the typing analogy from Question 36.)arrow_forwardREFLECT AND APPLY Is the following statement true or false? Why? The flow of genetic information in the cell is always DNARNAprotein.arrow_forward
- REFLECT AND APPLY Why is it more important for DNA to be replicated accurately than transcribed accurately?arrow_forwardRECALL Give the sequence on the opposite strand for ACGTAT, AGATCT, and ATGGTA (all read 53).arrow_forwardRECALL What are the main procedures involved in a western blot?arrow_forward
- REFLECT AND APPLY List three mechanisms that relax the twisting stress in helical DNA molecules.arrow_forwardREFLECT AND APPLY Give the DNA sequence for the template strand that gives rise to the following sequence gel, prepared using the Sanger method with a radioactive label at the 5' end of the primer.arrow_forwardREFLECT AND APPLY Suggest a reason why it would be unlikely for replication to take place without unwinding the DNA helix.arrow_forward
- RECALL What would be an advantage of using HaeIII for a cloning experiment? What would be a disadvantage?arrow_forwardREFLECT AND APPLY In the MeselsonStahl experiment that established the semiconservative nature of DNA replication, the extraction method produced short fragments of DNA. What sort of results might have been obtained with longer pieces of DNA?arrow_forward
