You've identified a gene likely involved in a human disease.
Question 3You've identified a gene likely involved in a human disease. You BLAST the predicted protein sequence for the gene against the database of known protein sequences and see that a domain of your unknown protein is similar to the nuclease domain of a RISC complex protein. Therefore... Select one: a. The unknown gene is likely to be a microRNA gene b. The unknown protein is likely to be a nuclease that cuts RNA c. The unknown protein is likely to be a nuclease...

Use the following information to answer the questions below. You have isolated a gene sequence from the mustard plant Arabidopsis and have BLAST searched the NCBI database. Your sequence hit several EST sequences that were identified as transcription factors. These sequences were found in E.coli, Chlamydomonas (a green algae), yeast, mice, and humans and only had a few base pair differences. What can be surmised about your transcription factor? It is unique to Arabidopsis. It is likely involved in a...

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...

Mendelian Genetics The gene involved in the disease Sickle Cell Anemia (SCA) is on human chromosome 11. Allele “A” is the normal form of the gene and codes for a part of the protein complex called hemoglobin. Hemoglobin is required for your blood cells to carry oxygen. Allele “a” is an abnormal form of the gene. The hemoglobin protein made from the “a” allele is defective. Red blood cells containing the defective protein are very fragile. This disease is recessive–meaning...

5. Professor Clueless has just identified a novel sequence X that s VERY similar to sequence Y as shown by the alignment in Figure 16.2. On the other hand, when he uses blast to find homologs of X against genbank (Figure 16.3), he obtains VERY different results from a blastn with query sequence Y (Figure 16.4). With such similarity between X and Y, he was expecting the two queries to get very similar results. What advice will you give the...

QUESTION 1: You are inserting a gene into an MCS found within the LacZ gene. Using blue/white colony selection, why could you assume that white colonies have modified plasmids? a. A blue colony means the LacZ reading-frame was disrupted b. A blue colony means your gene has mutations c. A white colony means the LacZ reading-frame is intact d. A white colony means the LacZ reading-frame was disrupted QUESTION 2: You are performing a PCR using primers with a sequence perfectly...

2. A dominant allele H reduces the number of body bristles that Drosophila flies have, giving rise to a “hairless” phenotype. In the homozygous condition, H is lethal. An independently assorting dominant allele S has no effect on bristle number except in the presence of H, in which case a single dose of S suppresses the hairless phenotype, thus restoring the "hairy" phenotype. However, S also is lethal in the homozygous (S/S) condition. What ratio of hairy to hairless flies...
