A new life form was discovered on Mars, one based upon Silicon instead of Carbon. Explain what properties Silicon has that allow
Vesna [10]

Group IV of the Periodic Table of the Elements contains carbon (C), silicon (Si) and several heavy metals. Carbon, of course, is the building block of life as we know it. So is it possible that a planet exists in some other solar system where silicon substitutes for carbon? Several science fiction stories feature silicon-based life-forms--sentient crystals, gruesome golden grains of sand and even a creature whose spoor or scat was bricks of silica left behind. The novellas are good reading, but there are a few problems with the chemistry.

CRYSTALLINE CREATURES? Silicon can grow into a number of lifelike structures, but its chemistry makes it unlikely that it could be the basis for alien life-forms.</span>

Indeed, carbon and silicon share many characteristics. Each has a so-called valence of four--meaning that individual atoms make four bonds with other elements in forming chemical compounds. Each element bonds to oxygen. Each forms long chains, called polymers, in which it alternates with oxygen. In the simplest case, carbon yields a polymer called poly-acetal, a plastic used in synthetic fibers and equipment. Silicon yields polymeric silicones, which we use to waterproof cloth or lubricate metal and plastic parts.

During the sequencing of dna into a protein, what is the first step
makkiz [27]
The first step in sequencing of DNA into a protein is called transcription. Transcription refers to transcribing a strand of DNA to a single strand of messenger rNA or mRNA. The mRNA is then modified (removal of introns, splicing of exons, adding the 5' cap and the poly-A tail, etc) then transported to the nucleus. The second step is called translation. Translation is refers to translating the mRNA strand into its corresponding amino acid based on codon sequences.
