In muscle phosphorylase, binding of ATP makes the protein tend to be in the T state, while binding of AMP makes the protein tend to be in the R state
A mouse has genotype AaBb. He inherited both dominant alleles (A and B) from his mother and both recessive alleles (aand b) from his father
In mid afternoon, they are on it's under surface, each caterpillar hanging by a few legs. Offer a hypothesis to explain this behaviour. How would you test it.
If a double heterozygous plant were crossed with a plant that has green stems and red fruit, what offspring phenotypes would be expected and in what proportions.
Homologous chromosomes separate and are pulled to opposite sides of the cell during what stage of cell division? (Read each option carefully.)
The restriction enzyme NiaIV cleaves the recognition sequencesGGNNCC between the 2 N’s (N stands for any nucleotide). How many NIaIV cutting sites arepossible? How many of these are palindromes?
The relative electrophoretic mobilities of a thirty kd protein and a 92-kd protein used as standards on an SDS polyacrylamide gel are 0.80 and 0.41, respectively.
The Fas ligand is a trimeric, extracellular protein that binds to its receptor, Fas. The binding of Fas ligand to its receptor alters the conformation of Fas so that it binds an adaptor protein and activates caspase-8.
Is Calcium important in the physical contraction of the heart.
In this situation, you sampled gene pool without replacing beads in the beaker after you drew each one.
compare and contrast how genotype and phenotype are determined in normal sexual reproduction with how they are determined in this type of cloning.
All three major types of RNA are processed before they are mature. They are derived from precursor RNA molecules that are considerably longer than the final RNA product.
