What diffuses out of mitochondria where it is synthesized?
Golgi apparatus: packages the proteins for discharge out of the cell. Carried in vesicles from the rough ER to the Golgi apparatus to the plasma membrane… Proteins. Diffuses out of mitochondria where it is synthesized…
Which type of RNA sends messages?
The type of RNA that contains the information for making a protein is called messenger RNA (mRNA) because it carries the information, or message, from the DNA out of the nucleus into the cytoplasm.
What is the process of copying RNA?
Transcription is the process by which the information in a strand of DNA is copied into a new molecule of messenger RNA (mRNA). Transcription is carried out by an enzyme called RNA polymerase and a number of accessory proteins called transcription factors.
How does RNA get out of the nucleus?
Messenger RNA, or mRNA, leaves the nucleus through pores in the nuclear membrane. These pores control the passage of molecules between the nucleus and the cytoplasm. mRNA processing occurs only in eukaryotes.
How is ATP transported out of the mitochondria?
Mitochondrial ADP/ATP carriers transport ADP into the mitochondrial matrix for ATP synthesis, and ATP out to fuel the cell, by cycling between cytoplasmic-open and matrix-open states. The cytoplasmic side of the carrier is closed by conserved hydrophobic residues, and a salt bridge network, braced by tyrosines.
What is the role of messenger RNA?
Specifically, messenger RNA (mRNA) carries the protein blueprint from a cell’s DNA to its ribosomes, which are the “machines” that drive protein synthesis. Transfer RNA (tRNA) then carries the appropriate amino acids into the ribosome for inclusion in the new protein.
What is the process of copying a DNA called?
Replication is the process by which a double-stranded DNA molecule is copied to produce two identical DNA molecules. DNA replication is one of the most basic processes that occurs within a cell. To accomplish this, each strand of existing DNA acts as a template for replication.
What happens during RNA processing before it can leave the nucleus?
Before leaving the nucleus as mRNA, eukaryotic transcripts are modified or processed in several ways. Both exons and introns are transcribed from DNA into RNA. However before the RNA leaves the nucleus the introns are removed and the exons are joined to produce an mRNA molecule with a continuous coding sequence.
