A single mRNA strand is attached to sevaral ribosomes?

AI Thread Summary
Several ribosomes can indeed attach to a single mRNA strand simultaneously, forming structures known as polysomes. This arrangement allows for the efficient translation of mRNA into proteins, as multiple ribosomes work on the same strand at the same time. The concept is illustrated in the provided link, which visually represents this process.

My book says that ' several ribosomes work on the same mRNA strand at the same time.'
Does this mean that a single mRNA strand is attached to sevaral ribosomes?

Rather several ribosomes are attached to an mRNA strand: polysomes

Thread 'I need help understanding this quote about recent Natural Selection'

I am reading Nicholas Wade's book A Troublesome Inheritance. Please let's not make this thread a critique about the merits or demerits of the book. This thread is my attempt to understanding the evidence that Natural Selection in the human genome was recent and regional. On Page 103 of A Troublesome Inheritance, Wade writes the following: "The regional nature of selection was first made evident in a genomewide scan undertaken by Jonathan Pritchard, a population geneticist at the...
