Question
Chapter 21.2, Problem 1CC
Summary Introduction
To explain: The two reasons due to which group of species shown in part (a) varies in their total amount of DNA.
Introduction: There exists a wide variety of organism in the environment. Different organisms have different types of genomes that make them unique. Animal and plants are highly different from each other. However, they both belong to the category of eukaryotes. Similarly, there are various similar species that share a difference in their total amount of DNA.

Whole-exome sequencing (WES) is helping physicians diagnose a genetic condition that has defied diagnosis by traditional means. The implication here is that exons in the nuclear genome are sequenced in the hopes that, by comparison with the genomes of nonaffected individuals, a diagnosis might be revealed. (a) What are the strengths and weaknesses of this approach? (b) If you were ordering WES for a patient, would you also include an analysis of the patient’s mitochondrial genome?
Question:-
When large genomes are sequenced, which of the following is true?
Group of answer choices
The genomes are converted from RNA to cDNA using reverse transcriptase, and then the cDNA is sequenced.
The genomes are fragmented, the DNA fragments are sequenced by any number of methods, and the sequences assembled to provide the original complete genome.
Sanger dideoxy sequencing is never used – instead, only nanopore sequencing is used.
The assembled sequences must have all gaps closed if the genome is to be useful for the research community.
Question:-
Which characteristics would you expect to be indicativeof horizontal gene transfer?T / F A significant change in %GC in part of the genome of an organismT / F Deletions of gene in the genomeT / F An insertion of a stretch of DNA when aligning sequences from closely related speciesT / F Missing genomic DNA sequences when aligning sequences from closely related speciesT / F Duplications of genes in parts of the genome

- Paraphrase and add more information "This study will concentrate solely on the molecular characterization of seaweed samples collected on Panglao island inSouth-Central Luzon, Philippines. Molecular data will be limited to DNA sequences, with identification relying heavily on Genbank returns via blastN. The researchers would obtain their samples from the generated database and analyze the DNA barcode of each macroalgae. The researchers would also compare the previous list of discovered seaweeds from Panglao island to generate a new and updated version for this study. The research would no text end outside or to the neighboring islands around Panglao, Bohol. Neither would the researchers add or include specimens that did not appear in the database or originate from Panglao island. The data to be considered would also not discuss or include the entire taxonomic key of each available sample."arrow_forwardDescribe the difference between Sanger based sequencing and Next Generation Sequencing (NGS). Why is NGS advantageous over Sanger based sequencing?arrow_forwardQuestion:- When completing genome sequences, contiguous sequences, or contigs are important intermediates. Which of the following is true about contigs? Group of answer choices The smaller the contig, the better it is for a complete genome assembly. A contig represents the sequence production from a single sequencing reaction. A contig is the name for a fragment of DNA made from a larger genomic DNA or chromosome, prior to its sequencing. A contig represents a DNA sequence assembled from smaller sequencing reads, and has no gaps.arrow_forward
- 2c) If the whole potoroo genome is 4.2 x 10' bp, and the highlyrepetitive DNA in the potoroo genome is composed entirely ofcopies of the sequence 5'AAGACT' and its complement, howmany copies of this sequence are present in the potoroogenome?arrow_forwardThe technique of fluorescence in situ hybridization (FISH) is described. This is another method for examining sequence complexity within a genome. In this method, a DNA sequence, such as a particular gene sequence, can be detected within an intact chromosome by using a DNA probe that is complementary to the sequence.For example, let’s consider the β-globin gene, which isfound on human chromosome 11. A probe complementary to theβ-globin gene binds to that gene and shows up as a brightly colored spot on human chromosome 11. In this way, researchers can detectwhere the β-globin gene is located within a set of chromosomes. Becausethe β-globin gene is unique and because human cells are diploid(i.e., have two copies of each chromosome), a FISH experimentshows two bright spots per cell; the probe binds to each copy ofchromosome 11. What would you expect to see if you used thefollowing types of probes?A. A probe complementary to the Alu sequenceB. A probe complementary to a tandem array near…arrow_forwardQUESTION: what difficulty will you experience if you do genetic manipulation to streptomyces spp. and how can this difficulty overcome ?? how could you modulate the gene expression for improving the productivity of an antibiotic produced by the streptomyces strain ? discuss with diagramarrow_forward

This is a result of what process? Retro transposition of mobile sequences Evolutionary conservation, exon duplication and exon shuffling Evolutionary conversion of leucine zipper, helix-turn-helix, and helix-loop-helix domains into zinc finger domains Evolutionary selection for proteins that interfere with nucleosome packing Genes that “jump” with the help of a transposase.arrow_forward
