Sidney brenner argued that the code was nonoverlapping because he considered that coding restrictions would occur if it were overlapping. a second major argument against an overlapping code involved the effect of a single nucleotide change. in an overlapping code adjacent amino acids would be affected by a point mutation, while in a nonoverlapping code amino acid(s) would be affected.

Sidney Brenner argued that the code was nonoverlapping because he considered that coding restrictions would occur if it were overlapping. A second major argument against an overlapping code involved the effect of a single nucleotide change. In an overlapping code TWO adjacent amino acids would be affected by a point mutation, while in a nonoverlapping code ONE amino acid(s) would be affected.

ANSWER:

TWO

ONE

the correct answer is 4) heat and pressure

metamorphic rocks arise from transformation of existing rocks types, in a process called metamorphism. during metamorphism the original rock(prolith) change into metamorphic rock by heating (150-200c) and pressure of more than 1000 bar. the original rock can be sedimentary, igneous, or existing metamorphic rock.
