Mitochondrial DNA (mtDNA) is genetically identical to Select one: a. DNA found in the nucleus of the cell b. Other siblings of the same father c. Mitochondria found in other species d. Mother’s and father’s mtDNA e. Other siblings of the same mother

Explain each options

Gregor mendels experiments sought to discover if he could find the rules that govern A. Genetics B. Heredity C. Meiosis D. Mutations

You are working in the lab and have measured the size of mRNA that has been transcribed from a particular gene in your cell population. The length of the gene in the cells you are working, measured from the start to the stop sequence is 9000 nucleotides. When you measure the RNA, however, the size is only 3000 nucleotides. What do you think happened? O a. Three DNA base pairs code for one RNA nucleotide. b. mRNA does not contain exons. c. There must have been a deletion mutation in the DNA in these cells. Od. The poly-A tail is present in the DNA but not on the mRNA. Oe. RNA splicing occurred, so introns are removed in the mRNA.
