Macromolecules are also known as polymer molecules
Pyrimidines are single-ringed nitrogenous bases that include Uracil, Cytosine, and Thymine.
If any of these three nitrogen bases are part of the multiple choice, then it should be the answer. I just took the test and for me it was Thymine.
A frameshift mutation is a mutation which changes the sequence read and transcribed by the ribsome, also presenting the possibility of coding for the wrong amino acid. You can have two types; frameshift substitution or frameshift deletion. In a substitution, a mutation occurs, adding a new basepair and shift the sequence read to the right. In a deletion, a mutation deletes a base pair and moves the sequence read to the left.
frameshift substitution: CGG TAT
frameshift deletion: CTA T
Fish are important to humans for many reasons. One reason is because they are a source of food. Another being the simply are in a good Cham for bigger predators who we do not want to go extinct.
