DNA
What complementary bases would bind with ATGGCTAA
TACCGATT
Biochemical cycles help maintain ecosystem homeostasis. Disruptions to these cycles affect ecosystem stability. What are the consequences of disrupting the nitrogen cycle.
Eutrophication which leads to algal blooms and dead zones and acid rain and damage to forest and aquatic ecosystems
What part of a DNA molecule is responsible for the direct coding of specific traits in a organism?
The sequence of nucleotide bases in the DNA molecule.
Which conclusion about the relatedness of the lizards do these data support?
G. Simonyi and G. bravoana are the most closely related.
Keritan is a structural protein found in hair and nails. What provides the instructions that determine the specific sequence of amino acids in keritan?
The sequence of nucleotides in the gene for keratin.
how did humans evolve?
through natural selection
Differences in traits such as hair texture are determined by differences in
the order of nitrogenous bases along the DNA
what is evolution?
The process of which things change overtime through natural selection.
what is substitution in a cell?
Process in which cells differentiate into specific types through the activation and expression of certain genes.
what is natural selection?
when organisms adapt to their environment
