Chapter 17, Problem 12TYU
Summary Introduction
To explain: The fidelity of the inheritance of DNA that relates to the evolution processes.
Concept introduction:
Evolution contributes to the diversity of life and, DNA forms the basis of continuity of life. The transmission of traits into next generations is known as the heredity and the heritable information is in the form of DNA. If there is any variation, then the natural selection works during evolution. This may result in different new species.

To explain: The extraordinary mutation resistance of
the genetic code argues in favor of its origin as a
frozen accident or as a result of natural selection.
All life shares DNA as the hereditary material. From an evolutionary perspective, why do you think this is the case?
Refer to Figure 2 and compare this with the DNA model in Figure 1.
a. In what ways are they similar?
b. In what ways are they different?
c. What is the biological significance of such differences? Why is the DNA referred to as the genetic material?

- 1. What are the 4 crucial characteristics of genetic material? Briefly describe how why each characteristic is applicable to DNA. 2. The following questions are about gene transcription and translation. a. Use the nucleotide sequence TGA CTA ACG GCT, transcribe into mRNA, and translate into a protein. b. Using this sequence, give an example of a synonymous, a non- synonymous and indel mutation. c. Which will have the biggest impact on protein evolution?arrow_forwardBackground: DNA nucleotides (i.e A, T, G, and C) are naturally found in a paired, or bonded, arrangement (i.e. the double helix) within the nucleus of every cell. This structure makes the process of replication that occurs prior to mitosis and meiosis very reliable. The purpose of DNA, though, is not simply to make copies of itself, but to provide a set of instructions for the synthesis or "construction" of biomolecules, such as proteins. Why is transcription (i.e. the formation of an RNA copy of a given gene) a necessary step in the "construction" process highlighted above? What is the cell looking to ultimately do with this RNA information?arrow_forwardIn a discussion about the origin of life, one student argued that RNA molecules must have come before DNA molecules. What is the most likely rationale for this argument? RNA can both store genetic information and catalyze chemical reactions, which are necessary for self-replication. RNA is more stable than DNA, making it more suitable for early life forms. RNA can replicate faster than DNA, enabling rapid evolution. RNA can translate genetic information into proteins, whereas DNA cannot.arrow_forward

These base-pair changes account for the physical differences seen between the two species. One difference between the two species is the shape of their hands and feet. Figure 1 compares the hand and a foot of a chimpanzee and a gorilla. Much like a human hand, chimpanzee and gorilla hands have opposable thumbs. This adaptation is good for picking up small objects and eating with one hand. Chimpanzees have fingers that are much longer and narrower than gorillas' fingers and have thumbs that are slightly smaller and sit farther down on their palms than gorillas' thumbs do.
