1 To visualize chromosomes, chromosomes must be: - Answer -extracted, stained with dyes and DNA probes Genetics - Answer -The study of inherited traits and their variation What notable event occurred in 1859? - Answer -Charles Darwin hypothesized pangenesis, and termed gemmules What was Darwin's provisional hypothesis of pangenesis? - Answer -Traits could be passed down through gemmules (small particles that traveled from every body part to the sexual organs where they were stored) According to Darwin, what was responsible for the transmission of characteristics from parent to offspring? - Answer -Gemmules What book did Charles Darwin write in 1859? - Answer -On the origin of species, or Preservation of Favored Races in the Struggle for Life True or false; Gregor Mendel's theories were immediately recognized in the world of science - Answer -false, Mendel's work was not recognized until the 20th century What two individuals have been credited for laying the foundation for formulating the theory of heredity? a.) Avery ET all and Miescher b.) Darwin and Morgan c.) Crick and Watson d.) Mendel and Darwin - Answer -d.) Darwin and Mendel Who developed the rules of inheritance in 1866? - Answer -Gregor Mendel 2 Rules of inheritance - Answer -Alleles of the same gene separate during gamete formation Alleles of different genes are inherited independently What did T. Hunt Morgan and his students study in 1911? - Answer -Fruit fly chromosomes -- determined that chromosomes carry genes What occurred in 1953 in the world of genetics? - Answer -The DNA double helix was determined Who determined the double helix structure of DNA - Answer -James Watson and Francis Crick What occurred in 1955 in the world of genetics? - Answer -Joe Hin Tijo defined 46 as the exact number of chromosomes in human cells Who discovered that there are precisely 46 chromosomes in the human cell? - Answer -Joe Hin Tijo What occurred in 1959 - Answer -Chromosome abnormalities were identified. Specifically, Down syndrome is caused by trisomy 21 Who discovered that Down syndrome is caused by trisomy 21? - Answer -J. Lejeune and his colleagues What occurred in 1966 that affected the world of genetics? - Answer -It was determined the genetic code that allows nucleic acids with their 4-letter alphabet to determine the order of 20 kinds of amino acids in protein s and R. Dahore What occurred in 1973 that affected the world of genetics? - Answer -The first animal gene was cloned How can we use the information derived from the human genome project? - Answer -1. Understand human disease better 2. More insight into human origins 3. Better insight into cognitive function 4. Identifying genetic susceptibility to disease 5. Personalize medicine The cancer genome atlas aims to identify: - Answer -All the genetic abnormalities seen in 50 major types of cancer What are the benefits of genomic sequencing? - Answer -1. Targeted interventions (drugs more effective and cause fewer side effects) 2. Makes it easier to diagnose, manage, and treat many diseases 3. Personalized medicine (focus efforts on specific strategies) Evolution depends on: - Answer -the occurrence, transmission, and spread of mutant genes in groups of organisms Phylogenic tree - Answer -represents the historical relationships among organisms DNA sequence data provides a way of studying: - Answer -the historical process of evolution Classical genetics is based on - Answer -The analysis of the outcomes of crosses between different strains of organisms HUMAN GENETICS (BMD 350) EXAM I TEST BANK Latest Verified Review 2024 Practice Questions and Answers for Exam Preparation, 100% Correct with Explanations, Highly Recommended, Download to Score A+ Who determined the genetic code in 1966? - Answer -M. Nirenberg, H. Khorana, Which of the following is false about classical genetics? a.) it can be coordinated with studies of the structure and behavior of chromosomes b.) It localizes genes to specific positions within chromosomes c.) It does not include transmission genetics nor does it study the nature of genetic material - Answer -c is false Chromosome mapping - Answer -Localizing genes to specific positions within chromosomes In classical genetic analysis, genes are studies by: - Answer -following the inheritance of traits in crosses between different strains of an organism Molecular genetics studies: - Answer -the replication, expression and mutation of genes at the molecular level Molecular genetics identifies: - Answer -Genes internal components, such as coding sequences, regulatory sequences, and non -coding sequences What is molecular genetics rooted in? - Answer -the study of DNA sequences and manipulation of DNA molecules Why is molecular genetics beneficial? - Answer -It gives us new ways to detect mutant allels and treat diseases In molecular genetic analysis, genes are studied by - Answer -isolating, sequencing, and manipulating DNA and by examining the products of gene expression True or false; individuals within a population always carry the same alleles of genes - Answer -false -- individuals may carry different alleles HUMAN GENETICS (BMD 350) EXAM I TEST BANK Latest Verified Review 2024 Practice Questions and Answers for Exam Preparation, 100% Correct with Explanations, Highly Recommended, Download to Score A+
