DNA provides instructions for RNA polymerase
At the Ribosomes.
When several ribosomes are attached to one mRNA strip it is called polysome.So, mRNA holds together the ribosomes in a polysome.
mRNA and tRNA work together to complete the process of translation, which is the second step of protein synthesis, in which the genetic code on the mRNA is translated into a sequence of amino acids by the tRNA.
mRNA and tRNA work together to complete the process of translation, which is the second step of protein synthesis, in which the genetic code on the mRNA is translated into a sequence of amino acids by the tRNA.
mRNA is synthesized through a process called transcription, where an RNA polymerase enzyme matches complementary RNA nucleotides to a DNA template strand. This results in the production of a single-stranded mRNA molecule that carries genetic information from the DNA to the ribosomes for protein synthesis.
The step of translation in which an mRNA, a small ribosomal subunit, and the initiator tRNA are aligned together is called initiation. This process occurs with the formation of the initiation complex, where the mRNA binds to the small ribosomal subunit and the initiator tRNA carrying methionine binds to the start codon on the mRNA.
In RNA processing, introns are removed from pre-mRNA to generate mature mRNA. Introns are non-coding regions of the pre-mRNA that do not contain instructions for protein synthesis. The remaining exons are spliced together to form the mature mRNA that can be translated into a protein.
mRNA bases are put into the correct order during a process called transcription. Enzymes called RNA polymerases transcribe the DNA template into mRNA by matching complementary bases (A with U, G with C) to ensure the correct sequence. This process is essential for making a functional mRNA that can be used to produce proteins.
Transcription
The noncoding segments of a gene that are removed from an mRNA transcript during post-transcriptional processing are called introns. The remaining coding segments of the mRNA transcript, called exons, are then spliced together to form the mature mRNA that will be translated into a protein.
The molecules and proteins involved in the transport of mRNA include mRNA itself, RNA-binding proteins, motor proteins like kinesin and dynein, and various transport factors. These components work together to ensure the proper movement of mRNA within the cell.
The first (primary) transcript from a protein coding gene is often called a pre-mRNA and contains both introns and exons. Pre-mRNA requires splicing (removal) of introns to produce the final mRNA molecule containing only exons
