Answer:
The four organelles that contribute to the synthesis, transport, packaging, and export of proteins to the extracellular environment are Nucleus, RIBOSOMES, rough endoplasmic recticulum and Golgi apparathus.
Explanation:
The nucleus is the organelle that produced RIBOSOMES.
RIBOSOMES are organelles responsible for protein synthesis production of proteins.
The protein produced by the RIBOSOMES are then gathered in the rough endoplasmic recticulum . It then export and transport the protein to Golgi apparatus. The Golgi apparatus modifies and package the protein.
Cysteine contributes to the three-dimensional structure of a protein by forming covalent bonds with an identical amino acid in another part of the protein.
<h3>
What is the Cysteine Structure?</h3>
- Covalent disulfide bonds form between the sulfhydryl (-SH) groups of cysteines in different parts of a protein are very important in determining the three-dimensional shape of the protein.
- is a HOOC-CH-(NH2)-CH2-SH proteinogenic amino acid that is semi-essential. Cysteine's thiol side chain frequently functions as a nucleophile in enzyme processes.
- The sign Cyz is occasionally used when a deprotonated catalytic residue is present.
- The sign Cym can also be used to usually denote the deprotonated form.
- The thiol is capable of being oxidized to produce the disulfide derivative cystine, which is crucial for many proteins' structural integrity. Cyx is sometimes used in this context. It carries the E identifier E920 when added to food.
- The codons UGU and UGC encode the amino acid cysteine.
- Cysteine and methionine, which contain sulfur, are more quickly oxidized than other amino acids.

Where are the answer choices?
Answer:
3' to 5'; 5' to 3'
Explanation:
The DNA strand with 3' to 5' polarity serves as a template for the process of transcription. Using the 3' to 5' DNA template strand, the enzyme RNA polymerase catalyzes the formation of RNA. The ribonucleotides are bonded together by phosphodiester bonds that are formed in 5' to 3' direction only. The formation of RNA occurs in 5' to 3' direction. The DNA template strand has a complementary nucleotide sequence to the newly synthesized RNA.
