Textbook Question
Chapter 21, Problem 6TYU
scientific inquiry The scientists mapping the SNPs In the human genome noticed that groups of SNPS tended to be inherited together, in blocks known as haplotypes, ranging in length from 5.000 to 200.000 base pairs There are as few as four or five commonly occurring combinations of SNPS per haplotype. Integrating what you'vc Iearncd throughout this chaptcr and this unit, propose an explanation for this Observation.

- Read This! Extensive research has been done to find similarities and differences in the DNA sequences of different an- imals. This work is very difficult and time consuming, but it can help biologists determine the evolution- ary ancestry of a species. For example, when investigating the human genome, biologists found that about 99.5% of the DNA sequences among humans are the same. Considering the wide variety of traits in the human population, we are a lot more similar than we are different. Humans share approximately 96% of their DNA sequences with chimpanzees, 85% with mice, and 75% with chickens. 16. Study the table below.

The physicist Stephen Hawking, famous for his theories about black holes, has lived past the age of 70 withamyotrophic lateral sclerosis (ALS), a paralyzing neurodegenerative disease that is usually fatal at a muchyounger age. Recently, geneticists discovered that amajor cause of ALS is the unusual expansion of ahexanucleotide repeat (5′-GGGGCC-3′) that lieswithin a gene called C9ORF72, at a location outside ofthe gene’s open reading frame (ORF). A single expanded allele is sufficient to cause ALS, but the reasonthe disease allele is dominant remains unclear. Someexperimental results support the theory that the allelemakes a toxic RNA containing the expanded repeat. Ifthis theory is correct, in what ways is the mutant ALScausing allele similar to the mutant allele that causesHuntington disease? In what ways is it similar to themutant allele that causes fragile X syndrome?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?
