Answer: When the protein for a particular gene is formed, the gene is expressed
Explanation:
Gene expression is the process in which the information from a gene is used for the synthesis of protein. The gene code for protein and the protein regulate the function of the cell in the body.
into RNA by the help of enzyme RNA polymerase. The next step is the translation in which the messenger RNA is decoded in the ribosome to produce a specific amino acid or the polypeptide chain that perform a specific function in the cell.
Mutation is a source but it is not the main source after it comes recombination in which 2 chromosomes with “normal” survival are taken from natural population of Drosophila and combined. Then comes immigration of genes in which the new chromosome mix in with different gene frequencies.
The correct option is C.
Pilli is a long protein filament which attach reproducing cells together during conjugation. This attachment allows the cells to exchange the genetic materials, that is, plasmid between them.
The part of the experiment in which the experimental factor has been removed is referred to as <span>the independent variable. </span>The dependent variable<span> is the element which is being measured in an experiment or evaluated in a mathematical equation.</span>
B. because the rock is formed and it goes younger as it grows the rock is still old on the inner layers but it adds new layers as it goes
