An mRNA strand, or messenger RNA, is a single-stranded molecule that carries genetic information from the DNA in the cell's nucleus to the ribosomes, where it is used to make proteins.
An mRNA strand is attached to ribosomes through the binding of its nucleotides to the complementary nucleotides on the ribosome's small subunit.
Ribosomes are responsible for translating the genetic information carried by the mRNA strand into a specific sequence of amino acids, which form proteins.
Yes, multiple ribosomes can attach to a single mRNA strand, forming a complex called a polyribosome or polysome. This allows for more efficient protein production.
The attachment of an mRNA strand to ribosomes is regulated by various factors, including the availability of ribosomes, the binding affinity between the mRNA and ribosomes, and the presence of specific regulatory proteins or molecules.
