Discuss the possible effects of a defective tubulin gene in a cell

Explain how a transcription factor ultimately determines whether or not a protein will be present in a given cell?

In the normal course of events within protein synthesis, which of the following is part of, or can directly attach to, a tRNA molecule? (mark all three correct answers) an adenine tail MRNA polymerase an amino acid an anti-codon a DNA triplet а codon ribosome O a transcription factor

Cystic fibrosis (CF) is a disorder caused by a random change in the gene that produces the cystic fibrosis transmembrane conductance regulator (CFTR) protein. In people with CF, random CFTR gene changes can disrupt the CFTR protein's normal production or function- ing. This protein is typically found in several organs, and as a result, the lungs, pancreas, di- gestive system, and other organs are affected. The symptoms of CF can range from breath- ing difficulties to recurrent infections. Which of the following best describes the effects of cystic fibrosis? A B с D Cystic fibrosis is caused by a gene with multiple alleles. Cystic fibrosis is inherited via incomplete dominance. Cystic fibrosis is a pleiotropic gene. Cystic fibrosis is caused due to polygenic inheritance.

1st answer choices: yes, no 2: yes, no 3:increase, decrease 4: a lot of mRNA or very little mRNA 5: less mRNA, more mRNA, or the same amount of mRNA

Give a detailed description of how the protein(KRAS) encoded for by your protein normally functions in a cell. What does it do? What does it regulate? Is it an enzyme, transcription factor, regulatory protein, etc.? How does it work?

Describe the specificity between the amino acid carried by a tRNA and a codon in mRNA.

Describe missense and nonsense mutations and how they are different from frameshift mutations. Be comprehensive and tailor your answer to explain the impact of these mutations on the protein expressed

ATP and GTP play a few roles during transcription and translation. What are two roles that ATP plays and one role that GTP plays? GO S x2 x2 i T: B I

how would the disruption of the Rb family of proteins lead to cancer? Describe the possible molecules and pathways that could be affected
