Which type of RNA is transcribed from DNA?
messenger RNA (mRNA)
What types of RNA are made from the DNA template?
a. Messenger RNA(mRNA), which carries the genetic information from DNA and is used as a template for protein synthesis. b. Ribosomal RNA(rRNA), which is a major constituent of the cellular particles called ribosomes on which protein synthesis actually takes place.
What molecule carries out transcription of DNA?
RNA polymerase
What part of DNA makes mRNA?
mRNA is “messenger” RNA. mRNA is synthesized in the nucleus using the nucleotide sequence of DNA as a template. This process requires nucleotide triphosphates as substrates and is catalyzed by the enzyme RNA polymerase II. The process of making mRNA from DNA is called transcription, and it occurs in the nucleus.
Which molecule is used to indicate which amino acid is needed?
anticodon – a sequence of three nucleotides on a tRNA molecule that bond to a complementary sequence on an mRNA molecule. The anticodon sequence determines the amino acid that the tRNA carries. DNA – the molecule that stores and encodes an organism’s genetic information.
What is the result of RNA translation?
The molecule that results from translation is protein — or more precisely, translation produces short sequences of amino acids called peptides that get stitched together and become proteins. Transfer RNA binds to amino acids and drags them over to the messenger RNA strand on the ribosome. …
How are DNA and RNA involved in protein synthesis?
When protein synthesis is taking place, enzymes link tRNA to amino acids in a highly specific manner. In this way, a genetic code in the DNA can be used to synthesize a protein at a distant location at the ribosome. The synthesis of mRNA, tRNA, and rRNA is accomplished by an enzyme called RNA polymerase. Transcription.
What are the cell structures where proteins are made?
Ribosomes produce proteins and are made of two components—RNA and protein. Ribosomes are produced in the nucleolus, a structure located inside the nucleus. Some ribosomes float freely in the cytoplasm. They produce proteins that will be used by other cells.
What transports proteins in a cell?
The Golgi apparatus transports and modifies proteins in eukaryotic cells. The Golgi apparatus is the central organelle mediating protein and lipid transport within the eukaryotic cell.
How many cell structures are there?
three parts
What structures do cells use to move?
The cytoskeleton is the component of the cell that makes cell movement possible. This network of fibers is spread throughout the cell’s cytoplasm and holds organelles in their proper place. Cytoskeleton fibers also move cells from one location to another in a fashion that resembles crawling.
What basic structure do all cells share?
All cells share four common components: (1) a plasma membrane, an outer covering that separates the cell’s interior from its surrounding environment; (2) cytoplasm, consisting of a jelly-like region within the cell in which other cellular components are found; (3) DNA, the genetic material of the cell; and (4) …
How do cells move?
Cell movement is a complex phenomenon primarily driven by the actin network beneath the cell membrane, and can be divided into three general components: protrusion of the leading edge of the cell, adhesion of the leading edge and deadhesion at the cell body and rear, and cytoskeletal contraction to pull the cell …
