Textbook Question
Chapter 24, Problem 10EQ
In this chapter, we considered a computer program that translates a DNA sequence into a polypeptide sequence. Instead of running this program, a researcher could simply look the codons up in a genetic code table and determine the sequence by hand. What are the advantages of running the program rather than doing the translation the old-fashioned way, by hand?

The genetic code uses three bases to encode one amino acid. Why can't the code use only two bases to encode each amino acid?
Geneticists have found that when they cut out a eukaryotic gene from genomic DNA that they can hybridize one of the strands of that gene to the mRNA for that gene by allowing the strands to hydrogen bond.
Why did the appearance of these hybridized strands provide evidence of the existence of introns in eukaryotic genes?

- You have isolated a transposable element from the human genome and have determined its DNA sequence.

When you compare nucleotide sequences of the S. typhimurium and E. coli genes, you find that their nucleotide sequences are only 87 percent identical. How would you interpret the observations? Please make sure to select ALL correct answer options. Because genetic code is redundant, changes in the DNA nucleotide sequence can occur without change to its encoded protein. Due to the flexibility in the third positions of most codons, the DNA sequence can accumulate changes without affecting protein structure. Natural selection will eliminate many deleterious amino acid changes. This will reduce the rate of change in the amino acid sequence and lead to sequence conservation of the proteins. Protein sequences are expected to evolve and…arrow_forwardIn 1964, Nirenberg and Leder used the triplet binding assay to determine specific codon assignments.

To do this, they used a chemical mutagen that they knew made single nucleotide changes, used this mutagen to conduct a screen for mutations that disrupted a particular gene, and collected a number of different mutations in this gene. Briefly describe the logic they used to deduce that the codon length is 3 nucleotides long.arrow_forward
