What molecules carry protein assembly instructions from the nucleus to the ribosome?
messenger RNA (mRNA), molecule in cells that carries codes from the DNA in the nucleus to the sites of protein synthesis in the cytoplasm (the ribosomes).
What carries the instructions the cell needs from the nucleus to the cytoplasm?
Summary. Messenger RNA (mRNA) carries the instructions from the nucleus to the cytoplasm. The other two forms of RNA, ribosomal RNA (rRNA) and transfer RNA (tRNA), are involved in the process of ordering the amino acids to make proteins. RNA is a nucleic acid, like DNA, but differs slightly in its structure.
What carries the instructions for protein?
Messenger RNA (mRNA)
Messenger RNA (mRNA) carries the instructions for making proteins. Like DNA, proteins are polymers: long chains assembled from prefab molecular units, which, in the case of proteins, are amino acids. A large molecular machine* called the ribosome translates the mRNA code and assembles the proteins.
What organelle uses instructions from the nucleus to make proteins?
Ribosomes
Ribosomes, large complexes of protein and ribonucleic acid (RNA), are the cellular organelles responsible for protein synthesis. They receive their “orders” for protein synthesis from the nucleus where the DNA is transcribed into messenger RNA (mRNA).
How does the nucleus control protein synthesis in the cytoplasm?
The nucleus controls protein synthesis in the cytoplasm by (1) Messenger RNA (mRNA) is transcribed in the nucleus from DNA instructions. –> (2) It then passes through nucleus pores into cytoplasm. –> (3) Finally, it attaches to ribosomes where the genetic message is translated into primary protein structure.
What carries genetic instructions from the nucleus to the cytosol?
Messenger RNA (mRNA) copies the genetic instructions from DNA in the nucleus, and carries the instructions to the cytoplasm.
What is tRNA role?
Transfer RNAs (tRNAs) are adaptor molecules that translate genetic information into protein sequence by delivering amino acids to the protein synthesis machinery during translation.
What carries proteins to the cytoplasm?
A vesicle is a small, membrane-bound sac that transports substances in cells. The ER moves proteins and other substances within eukaryotic cells. Vesicles that contain newly made proteins move through the cytoplasm from the ER to an organelle called the Golgi apparatus.
What carries instruction of the cell?
Answer and Explanation: Messenger RNA (mRNA) is the molecule that carries the instructions for making proteins from the nucleus into the cytoplasm.
Which organelle is responsible for assembling proteins?
Proteins are assembled at organelles called ribosomes. When proteins are destined to be part of the cell membrane or exported from the cell, the ribosomes assembling them attach to the endoplasmic reticulum, giving it a rough appearance.
How can protein be synthesized in the cytoplasm?
The Art of Protein Synthesis During transcription, DNA is used as a template to make a molecule of messenger RNA (mRNA). The molecule of mRNA then leaves the nucleus and goes to a ribosome in the cytoplasm, where translation occurs. During translation, the genetic code in mRNA is read and used to make a protein.
