Answer:
Row 1
T-tubule
Dihydropyridine (DHP) receptors of the transverse tubule membrane play two roles in excitation-contraction coupling in skeletal muscle: (a) they function as the voltage sensor which undergoes fast transition to control release of calcium from sarcoplasmic reticulum, and (b) they provide the conducting unit of a slowly ...
Row 2
Sarcolemma
Ryanodine receptors (RyRs) are located in the sarcoplasmic/endoplasmic reticulum membrane and are responsible for the release of Ca2+ from intracellular stores during excitation-contraction coupling in both cardiac and skeletal muscle.
Medulla is a set of cells that run through a piece of hair. Forensic scientists use them to determine which creature the hair came from.
Hello,
I think your answer may be <span>B.The drilling of fossil fuels could lead to an accident, like an oil spill, causing harm to the ocean environment. </span><span>
Im not 100% sure tho!</span>
Prophase, metaphase, anaphase, and telophase.
A different protein would be made. A cell has no way of knowing if the pair was A=T or T=A originally, so if they switch the cell will think it was that way all along. A different protein will be made (most of the time) because the mutation leaves no traces of itself for DNA repair mechanisms to detect (unlike mutations like cytosine turning into uracil or two thymines binding together, which the cell knows is an unnatural occurrence). So if the switch goes unnoticed, that gene will code for a different protein. This is because proteins are made of strings of amino acids, and the sequence determines a proteins shape and function. DNA codes for sequences of amino acids. Each amino acid is represented as three bases, so TGC will code for something different than AGC. This means that if TGC is mutated into AGC, the resulting protein will also have the wrong amino acid.
