When an extra nitrogenous base is inserted into the DNA sequence of a gene, the protein product of the gene is usually nonfunctional. Which of the following statements best explains why it is nonfunctional? The inserted base causes the DNA sequence to be transcribed into the RNA sequence in the opposite direction.
The inserted base increases the rate of translation in the corresponding mRNA sequence.
The inserted base causes the codons in the mRNA sequence to be incorrect for the desired protein.
The inserted base signals enzymes to translate the DNA sequence instead of the RNA sequence into the protein.

Listed in the item bank are some key terms and expressions associated with the categories seen in the venn diagram. to find out more information about items, some have more details available when you click on them. drag and drop each item onto the proper area of the diagram. if an item describes more than one category, be sure to place it in the overlapping space. viruses are tiny infectious pathogens that cause many different diseases, such as polio, and the flu. though they are similar to one celled organisms in some ways, in many ways they are very different. use the venn diagram below to show the similarities and differences between viruses and living organisms.
