Nucleic acids are isolated and analyzed from different cells in a mammal. How would the DNA sequence of a skin cell be different from the DNA of a nerve cell? How would the RNA isolated from a skin cell and a nerve cell be different? A stem cell is a cell that is not currently differentiated into a specific cell type but that retains the capacity to differentiate into different cell types (such as nerve and skin). How does the existence of stem cells help verify your answer to the preceding questions?

All EXCEPT which of the following statements are evidence that DNA, and not protein, is the genetic material in eukaryotes as well as bacteria? Group of answer choices DNA is located in the cell where the primary genetic function is known to occur. Introduction of a human DNA coding for insulin into bacteria results in bacterial cells that can produce human insulin All of these are evidence that DNA is the hereditary material in eukaryotes. Mice that are transgenic for DNA coding for rat growth hormone grow to be twice normal mouse size. UV light is most mutagenic at a wavelength at which DNA and RNA strongly absorb.
Please use information from the text below and your knowledge of biology to answer the final two (2) questions. In 2003, as a result of the Human Genome Project, the complete sequence of all the bases in human DNA was released to the public. Although knowing the entire sequence of bases has proven valuable, scientists are currently working to map genes. Mapping genes involves determining the exact location of each gene. Since much of human DNA does not code for a protein, it is challenging to figure out which segments are actual genes. Often, scientists look at the percent composition of bases in a segment of DNA. If the segment of DNA has a large percentage of C and G bases (together over 50%), it is likely that it is a gene and codes for a protein. 10. Is it likely this segment of DNA codes for a protein? State 'yes' or 'no' AND support your answer using information from the text.

A scientist analyzed the bases in a segment of DNA from a human skin cell to determine if it codes for a protein. The base A (Adenine) is 11% of the bases in this segment of DNA. Calculate the percentage of bases that would be C…
The words “transcribe” and “translate” are more commonly associated with language and dialogue. For example, a court reporter may transcribe what was said during a trial, or a popular book may be translated from Spanish into English. Why are “transcription” and “translation” such good descriptors for these processes in molecular biology?
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?
Which of the following experimental results was NOT evidence that DNA is the genetic molecule rather than proteins? a. When a virus was radioactively labelled, and the virus was allowed to infect a bacteria cell, radioactive virus DNA was found inside the bacteria cell while radioactive virus proteins were found outside the cell. b. Dead pathogenic bacteria cells combined with living nonpathogenic bacteria cells caused the creation of living pathogenic cells and thus the death of the host animal. c. Proteins are a class of macromolecules with the diversity and specificity needed for hereditary material. d. Nucleotide bases occur regularly, such that the number of adenines = number of thymines, and the number of guanines = number of cytosines.
All the cells of one organisms share the genome. However, during development, some cells develop into skin cells while others develop into muscle cells. How can the same genetic instructions result in two different cell types in the same organism? Thoroughly explain your answer.
Which statement best describes a genomic library? an initial amount of DNA can be multiplied into millions of copies a large collection of bacteria that are engineered to contain fragments of an organism's complete genome a collection of DNA sequences are arranged on a microscopic grid many small pieces of circular, double-stranded DNA that replicate independently of chromosomes contained in a nucleus
There are three basic steps of DNA extraction: cell lysis, separation, and extraction. In the procedure for extracting DNA from human cheek cells, which parts belong to or explain the aforementioned three basic steps? You may refer to the following procedure: http://www.planet-science.com/categories/experiments/biology/2012/03/extract-your-own-dna.aspx
You are studying a large eukaryotic gene that is 439,515 base pairs long. You find the polypeptide that this gene produces in liver cells is 46,771 amino acids long. Your colleague studies the function of this gene in brain cells, and finds the polypeptide produced in the brain is much larger – 61,438 amino acids long. How do you explain this difference? Possible Answers: A. The cell cycle of liver cells is much longer than that of brain cells. B. This is due to alternative splicing. in the brain C. There was a different complement of sequence-specific transcription factor binding sites in the CRM of the brain cells. D. There is no 5' cap added to the gene product from the liver cells.
Why do you think all organisms use nucleic acids for encoding genetic information? Why not use proteins or carbohydrates? What advantages might DNA have as the source of genetic information?
