What happens if there was a mutation in the Cyclin B Kinase?
What is Cyclin B would not be activated, so mitosis would not occur because structure equals function?
Which of the following helps to stabilize mRNA by inhibiting its degradation?
What is 5' cap and poly-A tail
What happens when one nucleotide pair is lost from the middle of the coding sequence of a gene?
In the mRNA, the reading frame downstream from the deletion is shifted, leading to a long string of incorrect amino acids in the polypeptide, and in most cases, a stop codon will arise, leading to premature termination. The polypeptide will most likely be nonfunctional.
