A researcher studying a member of the Conus genus of cone snails discovers that there are many dozens of slightly different vari

ants of venom proteins coded by closely related genes. What is the most likely explanation for this great variation? [Hint: The compounds likely diversified in a similar way as the multiple globin proteins in mammals did.]a.Multiple gene duplication events have led to the production of a paralogous multigene family.b.Hybridization between two snail species has left the offspring with multiple orthologous genes.c.Duplicated genes underwent incomplete gene conversion, leading to many errors in sequence.d.Concerted evolution resulted in the production of many venom genes, scattered throughout the genome.e.The last common ancestor of all cone snails had a diverse set of venom genes that have been inherited by all cone snails

Answer:

a. Multiple gene duplication events have led to the production of a paralogous multigene family.

Explanation:

A globin gene family consists of several clusters of related genes formed by duplication of an ancestral gene. The different variants of venom proteins coded by closely related genes can reply this ancestral gene, forming this way a globin gene family in Cone snails.

Nikitich [7]

Answer:

Apoprotein

Explanation:

A peptide is a molecule formed as a result of the linking of amino acid molecules by a peptide bond. The peptide is the backbone of polypeptides and subsequently, protein molecules. Enzymes are proteinous molecules that serve as biological catalysts. The prosthetic group of a protein/enzyme is a metallic attachment to the protein, which plays roles that are vital to its functioning.

However, when the peptide portion of a protein molecule lack its prosthetic group, the protein is called an APOPROTEIN.

crimeas [40]
Miller Urey experiment mimics the environment we had for earth billion of years ago. They put in inorganic molecules and came out with organic molecules. Other scientist thought that they messed up their experiment, but once other scientists recreated and tested. They saw that Miller and Urey were correct. And that helped them see that the origin of life can come from simple cells.
