1) RNA polymerase finds the promoter sequence on DNA.
2)RNA polymerase reads the DNA and builds complementary sequence.
3) Intron séquences are spliced out and exons are joined together.
4) The ends of the mature transcript are protected before it leaves the nucleus.
5) The mRNA attachés to the ribosome.
6) transfer RNA arrives at the ribosome and the anticodon complements to the mRNA codon.
7)amino acids form peptide bonds as tRNA molecules match the mRNA.
I don’t know but it’s either b or c
Answer:B)food
everything else is transported from those options except food. Hopefully this is right.
Answer:
- Liver cells are abundant in SER.
- The testes and ovaries are tissue types whose cells are abundant in SER.
- Cholesterol is made in the SER.
- Phospholipids are synthesized from cytosolic water soluble precursor molecules.
Explanation:
This is because liver cells contain enzymes that metabolize various lipid-soluble compounds.
This is because testes and ovaries produce steroid hormones (cholesterol is the precursor for their synthesis).
ER is the organelle at which all membrane lipids are synthesized.
Phospholipids are the main lipids that are the main structural components of the cell membrane. They are synthesized on the cytosolic side of the ER membrane, from water-soluble cytosolic precursors.
