f the sequence of bases on the mRNA codon is AUU, what would be the sequence of bases on the opposite strand assembled by the tRNA?(1 point) Responses TAA TAA UUA UUA ATT ATT UAA
The sequence of bases on the opposite strand assembled by the tRNA would be UAA.

Ribosome → Vesicle → Rough ER → Vesicle → Golgi Apparatus → Cell Membrane
Proteins are important molecules that are synthesized, transported, and used in cells in a multitude of ways. The rough endoplasmic reticulum and Golgi apparatus have parts to play in this system. These functions are __________, respectively. Identify the answer choice that correctly fills in the blank in the above passage. (1 point) Responses protein packaging and lipid production protein packaging and lipid production protein making and protein packaging protein making and protein packaging DNA packaging and DNA storing DNA packaging and DNA storing DNA making and DNA packaging
protein making and protein packaging
In which part of the cell do ribosomes perform protein synthesis?(1 point) Responses cytoplasm cytoplasm lysosome lysosome vacuole vacuole nucleus
Ribosomes perform protein synthesis in the cytoplasm.
What would happen to a cell that lacked smooth endoplasmic reticulum?(1 point) Responses It would not be able to replicate DNA. It would not be able to replicate DNA. It would not be able to produce tRNA. It would not be able to produce tRNA. Its cell membrane would be impermeable. Its cell membrane would be impermeable. It would not be able to make lipids. It would not be able to make lipids.
It would not be able to make lipids.
To determine the sequence of bases on the opposite strand assembled by tRNA, we need to use the complementary base pairing rules. In RNA, adenine (A) pairs with uracil (U), and cytosine (C) pairs with guanine (G).
The mRNA codon AUU consists of three bases: A, U, and U. To find the complementary bases, we can substitute U for A (since A pairs with U) and A for U (since U pairs with A). This gives us the base sequence of TAA.
Therefore, the sequence of bases on the opposite strand assembled by the tRNA for the given mRNA codon AUU is TAA.
