What are the similarities and differences between carrier proteins and channel proteins​
kvv77 [185]
* Channel proteins- these are proteins with a hydrophilic pore where specific ions are able to pass through the membrane. Each channel protein is specific to an ion. This is the only way ions can travel through the membrane. They are trans membrane proteins.

* Carrier proteins- these are proteins which allow larger or polar molecules through the membrane. They are trans membrane proteins.

Carrier proteins essentially “carry" signals that are not soluble in aqueous solution through the blood stream to their target cells. Carrier proteins for hydrophilic signals prevent degradation of the signal. Channel proteins are embedded in cell membranes. They often are receptors (though not always), and when activated, allow specific ions to pass through the membrane.

A channel protein is a special arrangement of amino acids which embeds in the cell membrane, providing a hydrophilic passageway for water and small, polar ions. Like all transport proteins, each channel protein has a size and shape which excludes all but the most specific molecules

The carrier protein facilitate diffusion of molecules across the cell membrane. The protein is imbedded in the cell membrane and covers the entire membrane. This is important because the carrier must transport the molecule in and out of the cell.

A segmented viral genome
Fynjy0 [20]
<h2>The correct option is (C)</h2>

Explanation:

  • A VIRUS consist of RNA or DNA Genes and are therfore known as RNA Virus or DNA Virus
  • RNA genomes is seen in majority of Viruses. Bacteriophages possess double stranded DNA genomes whereas Plant viruses possess single stranded RNA genomes
  • Viral genomes are linear, as we see in the adenoviruses and circular as we see in the polyomaviruses
  • The shape of the genome is not determined by the type of nucleic acid present in it.
  • The genome is often divided into separate parts, in RNA and DNA viruses, and thus we called as segmented.
