DNA stand for
Deoxyribonucleic acid
A chance to one or more portions of DNA molecules called
Mutation
A mutation is always harmful to the organism. True or false
False.
Mutational effects can be beneficial, harmful, or neutral, depending on their context or location
In what part of the cell is DNA found?
Nucleus
In the cell, DNA associate itself with proteins to form coiled, thread like structures called…
Chromosomes
What are the 3 component of a DNA nucleotide
Deoxyribose sugar, phosphate group, nitrogen bases
The shape of the DNA molecule 
Double helix
What are the DNA nucleotide pairs
Adenine + thymine
Guanine + cytosine
If your body is a house, your DNA would be the…?
Blue print
Name of the sugar fountain DNA back bone
Deoxyribose
Having one set of chromosome in the nucleus
Haploid
This is the non-sugar component of DNA backbone
Phosphate
Having two set of chromosome in the nucleus
Diploid
A word describing a cell whose DNA found within a nucleus
Eukaryotic
Protein which associate with DNA to form chromosome in the nucleus
Histones
What is nitrogenous
A base or the structure which actually paired together to link to stand of DNA molecule
Condensed DNA structure in the nucleus
Chromosomes
The structure is made up of one nitrogenous basis, one phosphate one sugar
Nucleotide
A change to the base sequence on DNA molecule
Mutation
What is complimentary?
A base pairing is what allowed DNA to replicate itself
These two scientist discovered the structure of the DNA molecules
Watson and Crick
What is substitution in mutation mean
is when one base in a DNA sequence is replaced by another.
What is inversion in mutation
Same letters but different orders (reverse)
What is positive mutation
A mutation that doesn’t necessarily harm you
