Answer: The most serious of these mutations will be the insertion of 2 bases. Becasue the genetic code is read in triplets, a 2 base insetion will alter the reading frame of the code causing a frameshift mutation meaning every amino acid after the site of the mutation will be incorrect.
It depends on what the big fish and the small fish eat
Answer:
genetic engineering is the process of using recombinant DNA technology to alter the genetic makeup of an organism. genetic engineering involves the direct manipulation of one or more genes.
Explanation:
ggene therapy seeks to alter genes to correct genetic defects and thus prevent or cure genetic diseases. genetic engineering aims to modify the genes to enhance the capabilities of the organism beyond what is normal.
Tar and other ingredients found in smoke act as carcinogens which can cause an uncontrolled growth of cells
Answer: Option E -- RNA Editing
Explanation:
It should be noted that, RNA editing can be defined as a molecular process via which some cells can make discrete changes to specific nucleotide sequences within an mRNA molecule after it has been generated by RNA polymerase. In addition, we have two major types of RNA editing with 1 being a C-to-U change catalyzed by cytidine deaminase that deaminates a cytidine base into a uridine base, e.g C-to-U editing is with the apolipoprotein B gene in humans. ApoB-100 is expressed in the liver and apoB-48 is expressed in the intestines. The B-100 form comprises of a CAA sequence that is edited to UAA, a stop codon, in the intestines.
