False
Verified step by step guidance1
Understand the relationship between genomic DNA size and organism complexity. Genomic size refers to the total amount of DNA contained within one copy of a single genome.
Recognize that complexity in organisms is not solely determined by the size of their genome. Complexity can also be influenced by factors such as gene regulation, the number of different cell types, and the interactions between genes.
Consider examples of organisms with large genomes that are not necessarily complex. For instance, some plants and amphibians have larger genomes than humans but are not considered more complex.
Acknowledge that some simple organisms, like certain bacteria, have small genomes but can exhibit complex behaviors due to efficient gene regulation and expression.
Conclude that the statement 'The larger the genomic DNA sequence is, the more complex the organism is' is false, as genome size does not directly correlate with organismal complexity.
