And clearly, DNA/RNA etc. follow specific patterns, and thus are not random by definition.

I do not remember anyone saying, nor even implying, they were. Patterns are found in nature all the time.

"I do not remember anyone saying, nor even implying, they were. Patterns are found in nature all the time."

It was me that said they were, not realizing that lack of pattern was one of the definitions of the word "random." That sentence in my post was meant as an acknowledgement of the "lack of pattern" part of the word's definition. Until this thread, I've been using "random" only to refer to lack of predetermined purpose or plan. Now I understand that lack of pattern is also included in the definition.
