Translation and protein synthesis is occurring at the ribosome. If the tRNA anticodon being matched at the ribosome is AUG, what

Bas_tet [7]

Answer:

The correct answer would be - option D) UAC.

Explanation:

By the process of the translation mRNA turns into protein as mRNA is considered as blueprint of the protein. During translation tRNA contains anti-codons or amino acid this anti-codon is correspond to the codon of mRNA.

The anticodon of tRNA which is present at the accept site or anticodon of tRNA molecule is complementary to the codon present in the mRNA which means A pairs with U and G pairs with C only.

Thus, the correct answer would be - option D) UAC.

What happens when potassium ions continue to enter into the neuron after generation of an action potential?

nadya68 [22]

As the action potential passes through, potassium channels stay open a little bit longer, and continue to let positive ions exit the neuron. This means that the cell temporarily hyperpolarizes, or gets even more negative than its resting state.
