Protein targeting in the cell is carried out via endoplasmic reticulum (ER) and mainly exported by Golgi apparatus (through vesicles). Proteins that have signal sequences will be destined to the nucleus and other organelles. Secretion of proteins to the cell membrane and out of cell by secretory vesicles.
What else can I help you with?
What will happen to the newly synthesized protein as a result?
The newly synthesized protein will undergo folding and post-translational modifications, which are crucial for its functionality. Once properly folded, the protein may be transported to its specific location within the cell or secreted outside the cell, depending on its role. Additionally, it will interact with other cellular molecules to perform its designated functions, such as catalyzing biochemical reactions or providing structural support. Ultimately, the protein's stability and activity will depend on its environment and the regulatory mechanisms in place.
What is a nascent polypeptide?
A nascent polypeptide is a newly synthesized chain of amino acids in the process of being formed by ribosomes during protein translation. It is still actively being synthesized and has not yet fully folded into its mature functional form.
IF DNA is labeled radioactive and allowed to replicate how much radioactivity in newly synthesized DNA?
The amount of radioactivity in the newly synthesized DNA will be equal to that of the original labeled DNA. Since the labeled DNA is used as a template for replication, the radioactivity is retained in the newly synthesized strands.
What structure directs newly made materials to where they need to go?
Golgi bodies
Which pathways is most likely taken by newly synthesized histones?
cytoplasm -> nucleus
How are newly synthesized integral proteins inserted into a membrane?
Newly synthesized integral proteins are guided to the membrane by signal sequences that target them to the endoplasmic reticulum (ER). Once at the ER, the proteins are translocated across the membrane through a channel formed by the translocon complex. The hydrophobic regions of the protein interact with the lipid bilayer, while the hydrophilic regions remain exposed to the aqueous environment, resulting in the protein being inserted into the membrane.

What is the protein synthesis termination triplet?
The protein synthesis termination triplet is the stop codon found in mRNA that signals the end of translation. The three stop codons are UAA, UAG, and UGA. When a ribosome encounters a stop codon, it signals the release of the newly synthesized protein.
Do primers anneal to newly synthesized strands?
Yes, primers anneal to the newly synthesized DNA strands during the process of polymerase chain reaction (PCR). Primers provide the starting point for DNA polymerase to initiate synthesis of the new DNA strand.
Is a newly synthesized strand half of the original stand with newly formed complimentary half?
Yes, during DNA replication, a newly synthesized strand is formed by pairing complementary nucleotides with the original strand. This results in one strand being the original and the other being newly synthesized, forming a complementary pair.
What does Oligosaccharide protein transferase do?
Oligosaccharide protein transferase is an enzyme that helps in the transfer of pre-assembled oligosaccharide chains from a lipid carrier to specific asparagine residues on newly synthesized proteins in the endoplasmic reticulum. This process is essential for proper protein folding and function.
What structure directs newly made materials to where they need to go?
Golgi bodies
What is newly synthesized genetic material?
Replicated Dna. Also, messenger Rna.
Which pathways is most likely taken by newly synthesized histones?
cytoplasm -> nucleus
What would occur last in the protein synthesis?
The last step in protein synthesis is termination, where the ribosome reaches a stop codon on the mRNA. This signals the release of the newly synthesized polypeptide chain from the ribosome. Subsequently, the ribosomal subunits and mRNA are also released, allowing the components to be recycled for future rounds of protein synthesis.
