Summary Introduction
To determine: The genome comparison between the per mega-base pair of genomic DNA in humans and rice.
Introduction: The genes are the sequence of
Expert Solution & Answer
Explanation of Solution
Thesize of the human genome is 3384 megabase pairs, whereas the genome size of rice, Oryza sativa is 373 to 400 megabase pairs. The number of human genes is around 35000 whereas the genome ofricecontains about 45000 to 56000 genes.
The ratio between the genome size of rice and humans will be about 10:1. The number of functional genes in rice is more than in human even though the genome size is ten times smaller than humans. The genomes in figure 24.1 that are most like humans in terms of the ratio of genes to base pairs are mouse and chimpanzee that are Mus musculus and Pan troglodytes, respectively.

The 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?

- What percentage of the DNA in the genome actually corresponds to genes? How much is actually protein-coding exons? What makes up the rest?arrow_forwardWhen the human genome sequence was finally completed, scientists were surprised to discover that the genome contains far fewer genes than expected. How many genes are present in the human genome? Scientists have also found that there are many more different kinds of proteins in the human cells that there are different genes in the genome. How can this be explained?arrow_forwardWhich one of the following options most accurately describes how the ~3000 megabases (Mb; ~3,000,000,000 nucleotides) of the haploid human genome are distributed on chromosomes? The haploid human genome is distributed on autosomes 1-22 and X and Y (so, 24 chromosomes). The haploid human genome is distributed on the homologous pairs of autosomes 1-22 and X and Y (so, 46 chromosomes). The haploid human genome is distributed on a single chromosome (so, 1 chromosome). The haploid human genome is distributed on one pair of homologous chromosomes (so, 2 chromosomes).arrow_forward
- What is the most ideal genetic model organism and discuss why?arrow_forwardWhen comparing evolutionary similarities between different genes within a gene family, it is usually more straightforward to compare genes by using the protein sequences of gene products rather than DNA sequences of the genes themselves. Explain why this is the case. (Write 5 points)arrow_forwardGiven our knowledge of genome sizes in different organisms, would you predict that Homo sapiens or the two-toed salamander (Amphiuma means) has the larger genome?arrow_forward
- The fruit fly Drosophila melanogaster has about 2 x 10^8 base pairs of DNA per haploid genome, of which about 75% in nonrepeated DNA. The DNA is distributed among four pairs of homologous chromosomes, which have a total of about 5,000 visible bands when in polytene forms in the salivary gland. The number of genes initially estimated from mutational studies was also about 5,000 but recent DNA sequencing studies suggest that the gene number may be somewhat higher. a. Why was it tempting to speculate that each band corresponds to a single gene? What does this suggest about the number of different proteins Drosophila can make? Does that seem like a reasonable number to you? b. Assuming all the nonrepeated DNA is uniformly distributed in the chromosomes, how much nonrepeated DNA (in base pairs) is there in average band?arrow_forwardThe human genome contains thousands of sequences known as small open reading frames, some of which encode proteins of about 30 amino acids. What is the minimum number of nucleotides required to encode such a protein?arrow_forwardUsing a laser beam, you isolated several R bands from human chromosomes. Answer the following questions What kinds of genes are present in R bands? Which isochors do you expect to be present in the R band? What class of interspersed repeats will be present in R bands? What class of tandem repeats do you expect to find in RG bands? Would you expect to find telomere sequences in some R bands?arrow_forward
- The Hemoglobin gene has two very common alleles: HbS and HbA. Bob’s professor asks him to draw the chromosomes for an individual that is HbSHbA and label the alleles. Bob draws this (below). Explain why Bob is wrong and then draw it correctly. FOXP2 is a gene in humans; humans that have mutated copies of FOXP2 often have trouble speaking. It is on Chromosome 7, which is about 160 million base pairs long. FOXP2 is at position 115 million base pairs. Which of the drawings below appropriately diagrams the location of FOXP2? Why?arrow_forwardA gene has length of 10000 nucleotides, some of them are ancestral (A) and others are mutant letters (M). Every generation 3% of the ancestral letters turn mutate and become M and 1% of the mutant letters revert to the ancestral state. Write a discrete time model for the number of the mutant nucleotides M (Hint: A = 10000 - M). If initially there are 0 mutant letters (all 10000 are ancestral), predict how many there will be in 10 generationsarrow_forwardThe Human Genome Project has demonstrated that in humans of all races and nationalities approximately 99.9 percent of the sequence is the same, yet different individuals can be identified by DNA fingerprinting techniques. What is one primary variation in the human genome that can be used to distinguish different individuals? Briefly explain your answer.arrow_forward
