Summary Introduction
To review:
Examples of the cellular proteins that are encoded by the members of gene families and their importance at the cellular level.
Introduction:
A gene family is formed after multiple duplications of a common evolutionary ancestor. Duplication or relocation are the two factors that lead to the formation of the gene family. These genes show the same biochemical functions.

Consider Molecule X, which is found in all living cells. This molecule is transcribed from a stretch of DNA in the nucleus. Each nucleobase on the DNA
produces a matching nucleobase on this molecule. Every 3-base codon specifies an amino acid in a protein.
What is the name of X? Your answer should be one word, or a short two- or three-word phrase. Spelling counts.
Note: if there is more than one possible answer, separate each answer with a comma.

All the cells of one organism share the same genome. However, during development, some cells develop into skin cells while others develop into muscle cells. Briefly explain how the same genetic instructions can result in two different cell types in the same organism.
Scientists are working to develop gene therapy to treat Batten disease, also known as Late Infantile Neuronal Ceroid Lipofuscinosis (LINCL). This fatal, autosomal recessive neurodegenerative disorder results from a mutation in the gene that codes for the enzyme TPP1 (Tripeptidyl peptidase 1). In the absence of this enzyme, a substance called ceroid lipofuscin accumulates in lysosomes in the brain, resulting in seizures, blindness, decline in cognitive function and motor skills, dementia, and death by the late teens or early 20’s. The TPP1 gene is 6695 bp in length. Think about the characteristics of Batten disease, and then suggest an approach to gene therapy that might be effective for this specific genetic disorder. You may assume that your research team is working in the U.S. and your research is funded by a grant from the National Institutes of Health (NIH).
1. Briefly outline a procedure that you could use to carry out the gene therapy for Batten disease.

- Like Hurler syndrome, Fabry disease involves an abnormal accumulationof substances within lysosomes. However, the lysosomes of individuals with Fabry disease show an abnormal accumulation of lipids. The defective enzyme is α-galactosidase A, which is a lysosomal enzyme that functions in lipid metabolism. The defect causes cell damage, especially to the kidneys, heart, and eyes. The gene that encodes α-galactosidase A is found on the X chromosome. Let’s suppose a phenotypically unaffected couple producestwo sons with Fabry disease and one phenotypically unaffecteddaughter. What is the probability that the daughter will have anaffected son?arrow_forwardThe continuity of life depends on a cell cycle during which genetic information is passed from a parent cell to daughter cells.

- Dystrophin is a protein that forms part of a vital protein complex that connects the cytoskeleton of a muscle fiber cell to the extracellular matrix. This connection strengthens and shapes the muscle fibers. Dystrophin is coded by the DMD gene. This is one of the longest human genes known, covering 2,300,000 base pairs (0.08% of the human genome) It is located in chromosome 21. The immature mRNA is 2,100,000 bases long and takes 16 hours to transcribe. It contains 79 exons. The mature mRNA measures 14,000 and codes for a protein with 3,685 amino acids. Abnormal expression of dystrophin leads to severe symptoms like muscle weakness and fatigability, a disease that is called muscular dystrophy. Most patients with muscular dystrophy become wheelchair dependent early in life. Cardiac muscle is also affected which results typically in premature death (~ second or third decade of life). Several mutations in this gene have led to the production of low levels of dystrophin or of a defective,…arrow_forwardA mutation creates a dominant negative allele of a particular gene. The gene encodes a protein that forms a trimer within the cell. If one or more of the subunits has the mutant structure, the entire trimeric protein is inactive.

- Many aspects of gene function can be nicely explained with the one-gene-one-enzyme hypothesis, which states that a gene controls the production of an enzyme. Which of the following findings about gene expression, though, requires an expansion of this simple concept? Choose an answer below: Non-enzyme proteins are made from genes too. Some genes code for RNA molecules only. Enzymes composed of different polypeptides are coded for by more than one gene. a and c, but not b a, b, and carrow_forwardWrite the word TRUE if the statement is correct and if false, replace the underlined words with the correct one. 1. Heterochromatin is typically gene-rich and composed of loosely-packed DNA that is transcriptionally active. 2. Molecular switches regulate the expression of genes by directing where and when genes should be turned on or off depending on the cell signal. 3. DNA Methylation and acetylation of histones are inverselycorrelated 4. Specialized cells produce specialized proteins derived from luxury genes which are constitutively expressed. 5. In mammals, methylation patterns that regulate DNA structure and gene expression become evident from the gastrula stage.arrow_forwardConsider a liver cell.

- A cultured mouse cell line has a mutation in a gene encoding a ribosomal protein. The mutant protein impairs the fidelity of translation such that incorrect amino acids are incorporated at higher rates than normal during protein synthesis. It also slows the rate of mRNA translation and increases the duration of the cell cycle, i.e., the mutant cells grow and divide more slowly. Researchers noted that these cells express higher levels of chaperone proteins than normal cells. Which of the following is the most likely explanation for the elevated chaperone levels.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_forwardYou are interested in the effects of mutations on the expression of a human protein- encoding gene expressed in skin cells. The gene has one intron that is 450 nucleotides long. After this intron is removed from the pre-mRNA, the mRNA transcript is 1100 nucleotides in length. Diploid somatic cells have two copies of this gene. Predict the size and amount of mRNA from the cytosol of skin cells, which were obtained from the following individuals: • Individual 1: Normal individual with no mutations in this gene. • Individual 2: Homozygous for a deletion that removes the -10 to -100 region of the gene that encodes this mRNA. • Individual 3: Heterozygous in which one gene is normal and the other gene has a deletion that removes the -10 to -100 region. • Individual 4: Homozygous for a five-nucleotide deletion in the intron that removes the GT sequence at the 5' splice site.
