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.

Students have asked these similar questions
The continuity of life is based on heritable information in the form of DNA, and structure and function are correlated at all levels of biological organization. In a short essay (100−150 words), describe how the structure of DNA is correlated with its role as the molecular basis of inheritance.
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?
Answer the following question briefly but intelligently.
1.) In your perspective, with the continuous modification of different organisms DNA, will genetic engineering permanently change our society?

James Watson and Francis Crick were the two scientists who received credit for identifying the structure of DNA. They based their findings on the work of Rosalind Franklin. Group of answer choices True False 7. Transcription uses a strand of DNA as a template or copy and makes a new strand of RNA which is used to eventually code for proteins.

Group of answer choices True False plz aNSWER ALLarrow_forwardwe have focused on DNA, the molecule that stores genetic information in all living things. In particular, we discussed its structure and delved into how weanalyze this molecule. Based on your knowledge of these topics,answer several fundamental questions: Question: How were we able to determine that DNA, and not someother molecule, serves as the genetic material in bacteria,bacteriophages, and eukaryotes?arrow_forward
- In the context of chemical evolution, DNA's structure is interesting because it suggests a possible copying mechanism. What about DNA's structure facilitates copying? A. The strands of the double helix are complementary. B. DNA always goes from 5' to 3'. C. It has the same number of purines and pyrimidines. D. The nitrogenous bases are located on the inside of the double helix.arrow_forwardIn the Meselson and Stahl experiment. E. coli cells grown on heavy nitrogen were transferred to light nitrogen.

- What are some of the ways that organisms use to ensure the fidelity of DNA replication? Why is it important that the fidelity of DNA replication is an evolutionary balance between faithful replication and the existence of some errors? Escherichia coli and other bacteria methylate adenines on the original strand to distinguish the original strand from the newly replicated strand of DNA. Why is this distinction important?arrow_forwardConcept 23. A gene is a discrete sequence of DNA nucleotides. This concept describes the discovery of the DNA sequencing technique that made modern biology and bioinformatics possible. The method was later used to sequence the human genome and genomes of many other organisms. This led to the accumulation of great numbers of nucleotide and protein sequences in the numerous databases. The concept 23 web page is here: http://www.dnaftb.org/23/ After reading the Concept page, answer the following questions. What was the Mendel’s definition of a gene? How was it different from the definition by Beadle and Tatum? Describe proteins based on the early sequencing efforts. What was the definition of a protein coding gene based on the genetic code? What are the beginning and ending codons of the gene’s protein coding sequence? What is the name of the method that makes use of a “defective” DNA nucleotide? After reviewing the Animation pages, answer the following…arrow_forwardHave you ever wondered how life on earth sprang up? Where does life come from and what does it take to be alive? Recently, researchers have synthesized ribose- the sugar involved in the backbone of RNA- in the lab based on ice commonly found in space. Previously researchers had synthesized pyrimidine bases cytosine, uracil and thymine; parts of the DNA/RNA alphabet. While others have collected amino acids from meteorites. Think about all the different components that need to work to replicate DNA, create mRNA messages, and translate those messages into proteins for the cell to use. In this post you will reflect on the possibility that all these things have come together to create life somewhere other than on earth. In this discussion, pick a side (yes or no) and answer the following question: Do you think life in outer space is possible? If YES, what might it look like? If NO, why do you think it is not possible? Please remember to add a question to engage your classmates in the…arrow_forward

A nucleic acid that contains the genetic instructions used in the development and functioning of all modern living organisms. b. The helix geometry of DNA is of B-Form. DNA is completely protected by the body, i.e., the body destroys enzymes that cleave DNA. DNA can be damaged by exposure to Ultra-violet rays. c. The pairing of bases: A-T (Adenine-Thymine), G-C (Guanine-Cytosine) d. Consists of a deoxyribose sugar, a phosphate backbone, four bases: adenine, guanine, cytosine and uracil. e.
