What will happen in a cell if the DNA ligase gene is mutated

To be considered a transcription factor, a protein must bind the DNA. True or False

What is the significance of transcription factors

The human genome sequence encodes many more mRNA transcripts than there are genes. Why isn’t the number the same?

What are the classes of mutations that can be made in the genetic code? In your own words describe how each class of mutation changes the protein that gets made

The transcription enzyme that catalyzes  a strand of RNA from a DNA template is called what?

What mutations can be caused by a single base change in coding exons?

Which enzyme is required for the movement in DNA-only transposons? Group of answer choices Reverse transcriptase and Integrase Reverse transcriptase and endonuclease Transposase Integrase   Reverse transcriptase Endonuclease

The mutagen that most often causes thymine dimers is/are ________. Group of answer choices ultraviolet light reactive oxidants (free radicals) 5-bromouracil ethylmethane sulfonate acetaldehyde

Any permanent change to the structure of DNA is considered a mutation. A somatic cell mutation affects only the individual organism, while a germline mutation is passed onto the next generation. For example, excessive amount of exposure to UV rays can lead to skin cancer. Although this type of mutation occurs in the somatic cells, every individual has different susceptibility to skin cell mutations upon exposure to UV rays. The susceptibility is located in the germ cell and is heritable. The individuals who choose to overexpose themselves to UV rays increase their likelihood of obtaining undesirable mutations in their somatic cells. Unlike suntanning, there are other activities we engage in that can lead to germline mutations. These activities should be avoided if possible as they lead to heritable mutations and cancer. Using 200 words or less, identify one human activity that can lead to a heritable mutation. Explain how it affects the individual and how it can be passed onto the…
