Introduction:
The Human Genome Project (HGP) was undertaken to determine the sequence of nucleotides in human DNA and to identify all its genes. The scientists had to decode the genetic code in the human genome. Although more than 99 percent of all
Answer to Problem 26A
Correct answer :
The correct answer is option C. single nucleotide polymorphisms
Explanation of Solution
Explanation/justification for the correct answer:
Option C. single nucleotide polymorphisms − Variations in specific nucleotides that are linked to human diseases are called single nucleotide polymorphisms or SNPs. These variations in the DNA sequence occur when a single nucleotide in the genome is altered. SNP maps may help scientists identify many genes associated with many genetic disorders.
Hence, this is the correct option.
Explanation for incorrect answer:
Option A. proteomes− Proteomes refer to all the proteins found in a cell. Genes are the primary information storage units whereas proteins are the machines of a cell. So study of functions of proteins is also very important. Variations in specific nucleotides that are linked to human diseases are called single nucleotide polymorphisms or SNPs and not proteomes. Hence, this is not the correct option.
Option B. haplotypes- Just as linked genes are inherited together,
Option D. genomes− The total number of genes in an organism is called genome. Genomes contain all the information needed for an organism to grow and survive. Hence, this is not the correct option.

- help tutor pleasearrow_forwardQ8. A researcher wants to study the effectiveness of a pill intended to reduce stomach heartburn in pregnant women. The researcher chooses randomly 400 women to participate in this experiment for 9 months of their pregnancy period. They all need to have the same diet. The researcher designs two groups of 200 participants: One group take the real medication intended to reduce heartburn, while the other group take placebo medication. In this study what are: Independent variable: Dependent variable: Control variable: Experimental group: " Control group: If the participants do not know who is consuming the real pills and who is consuming the sugar pills. This study is It happens that 40% of the participants do not find the treatment helpful and drop out after 6 months. The researcher throws out the data from subjects that drop out. What type of bias is there in this study? If the company who makes the medication funds this research, what type of bias might exist in this research work?arrow_forwardHow do I determine the inhertiance pattern from the pedigree diagram?arrow_forward
