- The 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_forwardWhat proportion of exons are repeated sequences in the human genome? Is 38% surprising?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_forward
- The Human Genome Project resulted in the identification of 20,000 genes that code for proteins in humans. On average, each gene can code for 4 different proteins. Which of the following processes explains how a single gene could code for more than one protein? A) the central dogma of molecular biology B) mutations C) alternative splicing D) redundancy in the genetic code E) the fact that there are three stop codonsarrow_forwardHow many nucleotides does the human genome contain?arrow_forwardWhat are paralogous and orthologous genes? What are some of the explanations for the finding that humans are a much more complex organism than the roundworm C. elegans, yet have only about 5 percent more protein- coding genes (21,000 versus 20,000)?arrow_forward
- What are some general conclusions from human genomic studies regarding the number of genes present and the relative proportion of the genome that performs genic functions?arrow_forward1) What is the human gene TRNT1? Explain what the wild type and mutant forms do. 2) What is the human gene TRNT1? Explain what the wild type and mutant forms do.arrow_forwardA hereditary disease is inherited as an autosomal recessive trait. The wild-type allele of the disease gene produces a mature mRNA that is 1250 nucleotides (nt) long. Molecular analysis shows that the mature mRNA consists of four exons that measure 400 nt (exon 1), 320 nt (exon 2), 230 nt (exon 3), and 300 nt (exon 4). A mother and father with two healthy children and two children with the disease have northern blot analysis performed. The results of the northern blot for each family member are shown below. a) Identify the genotype of each family member, using the size of mRNAs to indicate each allele. (For example, a person who is homozygous wild type is 1250/1250). b) Based on your analysis, what is the most likely molecular abnormality causing the disease allele?arrow_forward
- A group of scientists sequenced the genomes of 12 species of Drosophila (Drosophila 12 Genomes Consortium. 2007. Nature 450:203–218). Data on genome sizes and numbers of protein-encoding genes from this study are given in the accompanying table. Plot the number of protein-encoding genes as a function of genome size for the 12 species of Drosophila. Is there a relation between genome size and number of genes in fruit flies? How does this compare with the relation between genome size and number of genes across all eukaryotes?arrow_forwardhow can genomes with a relatively small number of genes produce the vast complexity of phenotypes that results in living organisms, including humans?arrow_forwardWhen the S.cerevisiae genome was sequenced and surveyed for possible genes, only about 40% of those genes had been previously identified in forward genetic screens. This left about 60% of predcited genes with no known function, leading some to dub the genes fun (function unknown) genes. a)As an approach to understanding the function of a certain fun gene, you wish to create a loss of function allele. How would you do this? b)You wish to know the physical location of the encoded protein product. How would you obtain such information?arrow_forward
