Ineed ! this is a 30 point ! which statement best describes the steps leading up to protein synthesis? ( 1 )the translation of dna to rna occurs in the cytoplasm; then, the transcription of rna occurs in the nucleus. ( 2 )the transcription of dna to rna occurs in the cytoplasm; then, the translation of rna occurs in the nucleus. ( 3 )the translation of dna to rna occurs in the nucleus; then, the transcription of rna occurs in the cytoplasm. ( 4 ) the transcription of dna to rna occurs in the nucleus; then, the translation of rna occurs in the cytoplasm.

Explanation:

Protein synthesis involves two major steps:

Transcription involves the formation of a nucleotide sequence complementary to the DNA molecule, with the pairing of a different base, Uracil, with Guanine instead of the usual Thymine base. This occurs in the nucleus of the cell, and the resulting molecule is known as the mRNA.

This mRNA is transported into the cytoplasm through the nuclear pore for the next step, translation. This is primarily accomplished by ribosomes and tRNA molecules which are present in the cytoplasm of the cell. The result of this step is the generation of a protein molecule.

he uptake of drugs from the intestine is often strongly influenced by diffusion. for example, consider a water-insoluble steroid for treating inflammation that is solubilized in aggregates of detergent molecules, called micelles. these micelles, aggregates of 80 soap molecules, have a molecular weight of 24,000, a diameter of 2.6 nm, and a charge of -27. the positively charge ions (counterions) in this system are na".
