How do the nucleus and ribosomes work together?
The nucleolus within the nucleus synthesizes ribosome subunits
, which are assembled into ribosomes outside the nucleus. The nucleus then supplies mRNA to the ribosomes to code for protein construction.
What is the relationship between the nucleolus and the ribosomes?
The nucleolus is a region found within the cell nucleus that is concerned with
producing and assembling the cell’s ribosomes
. Following assembly, ribosomes are transported to the cell cytoplasm where they serve as the sites for protein synthesis.
How do the nucleus and ribosomes work together to generate a protein chegg?
thank you Part A How do the nucleus and ribosomes work together to generate a protein 1
ribosomes migrate into the nucleus, attach to a gene in the DNA, and use the gene as a transcript to synthesize a specific protein 2 in the nucleus, DNA is transcribed to mRNA, which the ribosomes use as instructions to synthesize a
…
How do ribosomes enter the nucleus?
Ribosomal proteins are made in cytosol which then enter the nucleus
through nuclear pores
How do the nucleus and ribosomes work together to generate a protein quizlet?
How do the nucleus and ribosomes work together to generate a protein? In the nucleus,
an mRNA copy of a gene is produced which ribosomes use as instructions to synthesize (build) a specific protein
. … A tRNA binds a codon and the ribosome adds amino acids from each tRNA to the polypeptide chain.
How do cells interact to export proteins?
Vesicles fuse with the cell membrane, and proteins leave the cell by
exocytosis
. This organelle packages proteins for export from the cell in vesicles. These membrane spheres transport materials inside the cell.
Which RNA is important for the synthesis of polypeptides in the rough ER?
The
mRNA
molecule that codes for polypeptides destined to be synthesized on rough ER (rather than free ribosomes) contains a special sequence of nucleotides called signal codons.
What is the functional relationship between nucleus and ribosomes?
How do the nucleus and ribosomes work together? The nucleolus within the nucleus synthesizes ribosome subunits, which are assembled into ribosomes outside the nucleus.
The nucleus then supplies mRNA to the ribosomes to code for protein construction
.
Why is the nucleus the most important organelle?
Of all eukaryotic organelles, the nucleus is perhaps the most critical. In fact, the mere presence of a nucleus is considered one of the defining features of a eukaryotic cell. This structure is so important
because it is the site at which the cell’s DNA is housed and the process of interpreting it begins.
How do the nucleus and ER work together?
While the function of the nucleus is to act as the cell brain,
the ER functions as a manufacturing and packaging system
. It works closely with the Golgi apparatus, ribososmes, mRNA, and tRNA. Structurally, the endoplasmic reticulum is a network of membranes found throughout the cell and connected to the nucleus.
Do all cells have a nucleus?
Only the cells of advanced organisms, known
as eukaryotes, have a nucleus. Generally there is only one nucleus per cell, but there are exceptions, such as the cells of slime molds and the Siphonales group of algae. Simpler one-celled organisms (prokaryotes), like the bacteria and cyanobacteria, don’t have a nucleus.
Can mRNA travel back into the nucleus?
Due to this physical separation, messenger RNAs (mRNAs) must be exported to the cytoplasm where they direct protein synthesis, whereas proteins participate in the nuclear activities are imported into the nucleus. In addition, some types of RNAs reenter to the nucleus after being exported to the cytoplasm [1].
What cell makes ribosomes?
Ribosomes are produced by
nucleolus
.
Which two cell structures work together in the process of protein synthesis?
The two cell structures that are involved in protein synthesis are
the ribosome and the endoplasmic reticulum
.
Which organelle is responsible for the production of ATP?
Most eukaryotic cells contain many
mitochondria
, which occupy up to 25 percent of the volume of the cytoplasm. These complex organelles, the main sites of ATP production during aerobic metabolism, are among the largest organelles, generally exceeded in size only by the nucleus, vacuoles, and chloroplasts.
How do ribosomes and Golgi bodies work together?
In other words, the ER accepts
ribosome synthesize proteins
, folds them into cisternae (sacs) and transports them to Golgi. … The Golgi apparatus packs proteins synthesized by the ribosomes of the ER wherein the lipids wrap them in a membrane which is then exported from cells.
