Answer:

B. Nearly every amino acid translated after the error will create the wrong protein after the deletion of a base.

Explanation:

Generally, mutations occur in two ways: 1) a base replacement, where one base is replaced for another; 2) insertion or deletion, where a base is either incorrectly inserted or deleted from a codon.

When a nucleotide is wrongly inserted or deleted from a codon, the effects of this change can be extreme. An insertion or deletion can affect every codon in a particular genetic sequence.  For example, given the code:

GAU GAC UCC GCU AGG. It is the codes for the amino acids aspartate, aspartate, serine, alanine, and arginine. If the A in the GAU were to be deleted, the code would become GUG ACU CCG UAG G. It won't produce any right amino acid.

So, if the code becomes changes, it won't produce any amino acid or will produce the wrong amnio acid.

Austin, is her 16 year old son. The recommended calorie needs for adolescent males between the ages of 16- 18 are; 2,400 calories for non active adolescents, 2,800 calories for moderately active adolescents and 3200 calories for active adolescents.

which of the following explains the most likely effect of this toxin on the light reactions of photosynthesis?
ivanzaharov [21]

Answer:

Which of the following explains the most likely effect this toxin will have on the Calvin cycle? Carbon dioxide will not be converted into carbohydrates. The toxin inhibits RuBisCO from catalyzing the joining of carbon dioxide with RuBP. This prevents carbon fixation, so the Calvin cycle will not occur.
