3. (2 points) In the nematode roundworm, Caenorhabditis elegans, the LIN-14 protein controls the timing of certain cell divisions during development. LIN-14 protein levels are normally high in early development but decrease in the later stages. In a lin-4 mutant, the level of LIN-14 protein stays high throughout development, changing the pattern of cell divisions in the animal and producing defects in the shape of the animal. The lin-4 gene encodes a microRNA that binds to a sequence in the...

Genetics Worksheet Week 3: Gene Regulation and Epigenetics 1. Duchenne muscular dystrophy is caused by a mutation in a gene that is 2.5 million nucleotides in length and encodes a protein called dystrophin. The dystrophin protein itself is 3684 amino acids in length. Calculate below the approximate size of the mRNA that encodes dystrophin. Approximately what percentage of the gene that encodes dystrophin is intron sequence? The human genome encodes a much greater variety and number of proteins than the...

You are studying the regulatory DNA of a mouse gene expressed in developing heart, liver, and lung tissue. Your preliminary work has shown that heart and lung expression of this gene is controlled by a short fragment of DNA just upstream of the promoter. Based on this result, you decide to investigate this region further to understand its function. You decide to compare this sequence to the regulatory DNA of the same gene found in rats and humans. Using genome...
