Question
Chapter 18, Problem 27CONQ
Summary Introduction
To review:
The effects on replication of the given DNA (deoxyribonucleic acid) sequence after the following treatments:
Treatment with nitrous acid.
Treatment with nitrous acid, followed by its removal, and then continued replication of DNA.
Introduction:
Nitrous acid is a common chemical agent that can act as a mutagen and causes deamination of bases. This can lead to a cytosine (C) getting converted into uracil (U), or adenine (A) getting converted into hypoxanthine (H), which can cause mutations in the DNA sequence.

- Plekhg5 functions in bottle cell formation, and Shroom3 functions in neural plate closure, yet the phenotype of injecting mRNA of each into the animal pole of a fertilized egg is very similar. What is the phenotype, and why is the phenotype so similar? Is the phenotype going to be that there is a disruption of the formation of the neural tube for both of these because bottle cell formation is necessary for the neural plate to fold in forming the neural tube and Shroom3 is further needed to close the neural plate? So since both Plekhg5 and Shroom3 are used in forming the neural tube, injecting the mRNA will just lead to neural tube deformity?arrow_forwardWhat are some medical issues or health trends that may have a direct link to the idea of keeping fat out of diets?arrow_forwardwhat did charles darwin do in sciencearrow_forward
