Answer:
B)DNA plays a role in the growth and reproduction of organisms.
Explanation:
The function of DNA is to store all of the genetic information that an organism needs to develop, function, and reproduce.
 
        
             
        
        
        
Answer:
a sequence of three nucleotides which together form a unit of genetic code in a DNA or RNA molecule.
Explanation:
Codon. The genetic code (which includes the codon) serves as a basis for establishing how genes encoded in DNA are decoded into proteins. A critical interaction in protein synthesis is the interaction between the codon in messenger RNA (mRNA) and the anticodon in an aminoacyl-transfer RNA
 
        
             
        
        
        
Answer:
Frequency of allele "A" 
 Frequency of allele "a" 
Explanation:
Given, 
The alleles for flower color are A (yellow) and a (green) where A is dominant to a.
 The genotype frequencies are - 
 AA -  %
%
 Aa -  %
%
 aa-  %
%
so the frequency of allele A is equal to 

As per Hardy Weinberg's equation 1- 

Substituting the value of "p" in above equation, we get -

So the Frequency of allele "A" 
 Frequency of allele "a"
