Chapter 20, Problem 1MCQ

Summary Introduction

Introduction:

The molecular phylogeny is the main basis of the evolution of the fungal taxonomy. The classification systems are based on the evolutionary relationships between the groups and the classification is named as phylogenetic classification.

Expert Solution & Answer

Answer to Problem 1MCQ

Correct answer:

The most similar type of organism with the ancestral fungus is a chytrid. Therefore, option (d) is correct.

Explanation of Solution

Reason for the correct statement:

The ancestral fungus evolved into Chytridiomycetes first. Some of the Zygomycetes and Chytridiomycetes share a common ancestor. However, the Chytridiomycetes are closest to the ancestral fungus because of the similarities in the DNA (deoxyribonucleic acid) sequences.

Option (d) is given as “A chytrid”.

As, “the chytrids have the most similarities with the ancestral fungus because of the similarities in the DNA sequences”, is the right answer.

Hence, option (d) is correct.

Reasons for the incorrect statements:

Option (a), is given as “A bacterium”.

The bacteria are placed in the kingdom Monera and not fungi. Their evolution was different from fungus. Hence, it is a wrong answer.

Option (b), is given as “A plant”.

The plants belong to the kingdom Plantae and not fungi and the plants are more evolved than fungi. Hence, it is a wrong answer.

Option (c), is given as “A basidiomycete”.

The Basidiomycetes are considered as the most evolved fungi and hence they share very less similarities with the ancestral fungus. Hence, it is a wrong answer.

Hence, options (a), (b), and (c), are incorrect.

Conclusion

According to the DNA sequencing data, the Chytridiomycetes are considered as the most primitive types of fungi and the Basidiomycetes and Ascomycetes share a common ancestor and are more evolved than other phyla of fungi.

Svp je voulais demander l aide pour mon exercice

Imagine that you are a clinical geneticist. Your colleague is an oncologist who wants your help explaining the basics of genetics to their patient, who will be undergoing genetic testing in the coming weeks for possible acute myeloid leukemia (AML) induced by the radiation she had several years ago for breast cancer. Write a 1,050- to 1,225-word memo to your colleague. Include the following in your memo: An explanation of the molecular structure of DNA and RNA, highlighting both similarities and differences A description of the processes of transcription and translation An explanation of the differences between leading and lagging strands and how the DNA is replicated in each strand Reponses to the following common questions patients might ask about this type of genetic testing and genetic disorder: Does AML run in families? What genes are tested for?

Respond to the following in a minimum of 175 words: What are some potential consequences that could result if the processes of replication, transcription, and translation don’t function correctly? Provide an example of how you might explain these consequences in terms that patients might understand.
