The components that make up the genetic code are common to all organisms. If a segment of a gene contains 27 nucleotides, none of which are stop or starts codons, how many amino acids does this segment code for?

9 amino acids

Explanation:

A segment of a gene that has 27 nucleotides will code for 9 amino acids.

Each codon on the gene potentially represents an amino acid and a codon is made up of 3 nucleotides each. Hence, in order to find out the total number of amino acids that a gene segment with 27 nucleotides can code for, the number of nucleotides should be divided by 3.

    number of amino acids = number of nucleotides/3

                     27/3 = 9 codons/amino acids

one characteristic that is shared by all is a soft body. many

of these invertebrate animals also have an outer shell to protect their

body. oysters, clams, snails, and mussels are all mollusks. so are octopuses, squids, and slugs. mollusks live on land and in freshwater.
