Answer: The option that is not true is D) Each amino acid is specified by only one codon.
Codon can be defined as the sequence of three nucleotides ( present in DNA or mRNA) that corresponds to a particular amino acid. It helps in the process of translation as different amino acids ( that are linked to codons) are assembled to give a particular protein according to the sequence of codon.
There are 64 codons and 20 amino acids that make up the proteins present in the living systems. This indicates that several different codons can correspond to the same amino acid.
For instance, amino acid Valine is coded by four codons that is GUC, GUG, GUA, GUU.
Thus, option D) is incorrect.

Plate tectonic induced changes in the sea level could increase the total percentage of land area upto 40% or decrease it to as low as 17%
<h3>What are Tectonic plates?</h3>
Plate tectonics, whose name derives from the Late Latin tectonicus and the Ancient Greek letter v, which means "pertaining to building," According to the widely accepted scientific idea , the Earth's lithosphere is made up of many major tectonic plates that have been gently shifting for nearly 3.4 billion years
The model is based on the idea of continental drift, which was created in the early 20th century. After seafloor spreading was confirmed in the mid- to late 1960s, plate tectonics became largely accepted by geoscientists.
