What part of DNA nucleotide holds the genetic information?
Nitrogenous base
Cell that does not contain a nucleus or any other membrane-bound organelles. EX: Bacteria
Prokaryotic Cell
What happens when DNA replication makes a mistake?
Mutations
Why is DNA important?
It gives each cell instructions on how to do its job, holds genetic material.
Most cellular respiration takes place in the
Mitochondria
Cellular Energy is
What is Adenosine Triphosphate (ATP)
What is the enzyme that builds new DNA strands in replication, and is used during a PCR test
DNA Polymerase.
Define Phenotype with an example
Physical expression of a gene (Blue eyes, brown hair etc)
What does a virus need in order to reproduce?
A host cell
Is a virus living or non-living?
?
What is the purpose of ribosomes in a cell?
Site for Protein Synthesis.
The legs of crocodiles and mice have similar bone structures and develop in a similar way. What type of structures are the leg bones?
Homologous structures
What does it mean when an animal in an invertebrate
They do not have a vertebrate or backbone
What are the amino acids for the RNA strand:

A change in the sequence of nitrogen bases in a gene is called a
mutation
Define the terms dominant and recessive.
Dominant traits always block out the recessive traits.
