- "Whole-Genome Sequencing Is Widely Used for Sequencing and Assembling Entire Genomes". Explain this ?arrow_forwardThe Japanese canopy plant (Paris japonica) has one of the largest of all eukaryotic genomes, with approximately 150 billion base pairs, about 50 times the size of the human genome. In contrast, the bladderwort Utricularia gibba has one of the smallest plant genomes, with only 82 million base pairs. What predictions can you make about the genomes of these two species?arrow_forwardDescribe two things that you can learn by searching a computerized database for sequences that have similarities to a newly sequenced gene.arrow_forward
- After numerous herbaceous plants had their genomes sequenced, a woody plant finally joined the group, Populus trichocarpa (black cottonwood). Give and explain three reasons why this specific tree was chosen. Give and explain two reasons for the importance of adding a woody plant to the list of completed plant genome sequences.arrow_forwardThe type of model building used by Pauling and by Watson andCrick involved the use of ball-and-stick units. Now we can domodel building on a computer screen. Even though you may not befamiliar with this approach, discuss potential advantages of usingcomputers in molecular model building.arrow_forwardWhat is a database? What types of information are stored within adatabase? Where does the information come from? Discuss theobjectives of a genome database.arrow_forward
- Here is some information about the sequences: There are two images given; one with sequences and the other with a figure. All these sequences, “SEQUENCE_21” to “SEQUENCE_27” are in the same subfamily or “clade” of a large phylogenetic alignment of all Rab proteins in these three species (see “Image with a figure” for a full view of gene family in humans, plants and yeast, see the “D” branch towards the bottom of the tree in Figure). “SEQUENCE_28” is a different Rab protein (actually it is the Rab39 protein at the bottom of the tree). “SEQUENCE_21” is from yeast. “SEQUENCE_22” to “SEQUENCE_25” are from the plant, Arabidopsis. “SEQUENCE_26” and “SEQUENCE_27” are from humans. Question: Based on the information above, what can you speculate about the possible evolution of the genes that “SEQUENCE_21” to “SEQUENCE_27” represent?arrow_forwardWhile comparative genomics is fundamentally the study of the differences between the genomes of species, it can also give clues about functional genomics (the study of the biological functions that rely on genomic sequences i.e. related sequences that encode the various proteins within a family). How? Give an examplearrow_forwardIn genomes the potential duplicate/paralog share the same annotation but have lower sequence similiarity. Discuss what could have caused this difference and its possible driver.arrow_forward
- The plot shows a correlation between sequence error rate and cluster density on an Illumina flow cell. From your knowledge of how Illumina sequencing works, why do you think there is this correlation?arrow_forwardDescribe two of the applications for genome mapping.arrow_forwardCompare and contrast linkage analysis and genome-wide association studies. How are they similar? How are they different?arrow_forward
