Answer:
DNA is made of chains of four smaller molecules called "Nucleotides".
Explanation:
A molecule consisting of a nitrogen-containing base (adenine, guanine, thymine, or cytosine) in DNA is known as a nucleotides.
 
        
             
        
        
        
both alleles in the heterozygous
genotype are exhibit in the phenotypes.  Allele
is completely dominant over the other, and  it is the phenotype is a blend of the two
homozygous phenotypes, there are more than two forms of the same gene, and
there maybe one more superior form and several different phenotypes

Answer:
 5 bases 
Explanation:
If there are 17 amino acids and only 2 bases that can be combined in order to make a codon then:
for 4 bases  is 16 and it is not enough combination for all 17 amino acids
 is 16 and it is not enough combination for all 17 amino acids
for 5 bases  is 25 combinations (meaning that more than one codon could code for the same amino acid).
 is 25 combinations (meaning that more than one codon could code for the same amino acid).
 
        
                    
             
        
        
        
The correct answer is letter a. the forces are equal and opposite.
A car's windshield has the same force of the car while it is moving, if a humming bird flies towards a moving vehicle without the bird getting hurt, the bird and the car may be considered to have equal yet opposite forces, which left the hummingbird unharmed.
