Which RNA carries amino acids to the ribosome during translation?

In preparation for an electrophoresis procedure, enzymes are added to DNA in order

to

The organic compounds that scientists use to cut, copy, and move segments of DNA are

During the process of chromosome replication, a genetic error occurs. As a result, a sequence of events occurs as described below.

Event A: a protein with a new sequence of amino acids is produced

Event B: a DNA strand with an altered base sequence is formed

Event C: a new inheritable trait is expressed in an organism Event D: an mRNA strand with a new sequence of bases is synthesized

The usual order in which these events would occur is

DNA samples were taken from three different species and used to determine the amino acid sequence for a portion of a particular protein. The amino acids were then compared in order to determine which species were most closely related. Some of the information is shown on the table below.

What Codons Should be in the blank space?
