The diagram below shows part of the process of DNA transcription. Which mRNA base will go in location 1?  A.Uracil B.Cytosine C.
aleksley [76]
You did not include the diagram, but the answer is very easy to figure out. The  mRNA base that will go in location 1 depends on the DNA base in location 1:

If the DNA base is Adenine (A), the mRNA base will be Uracil (U)
If the DNA base is Thymine (T), the mRNA base will be Adenine (A)
If the DNA base is Cytosine (C), the mRNA base will be Guanine (G)
If the DNA base is Guanine in (G), the mRNA base will be Cytosine (C)

Suppose the human trait for hair type is controlled by a simple dominant and recessive relationship at one locus. Curly hair, C,
Zepler [3.9K]

Answer:

The frequency of the dominant allele, C = 0.2234

and the heterozygous genotype, Cc= 0.1736

Explanation:

Given -  

Curly hair, C, is the dominant allele, and straight hair, c, is the recessive allele

Thus, C is dominant over c

The genotype frequency of curly hair is 52 in 131 students

so, remaining 131-52 = 79 are straight hair students.  

Since straight hair is a recessive allele , the genotypic frequency of "cc" is  

\frac{79}{131}\\0.6030

Frequency of "cc" is represented by q^{2}

Thus frequency of allele "q"  

= \sqrt{0.6030} \\= 0.7765

As per Hardy Weinberg's I equation -  

p+q=1\\p + 0.7765=1\\p = 0.2234

As per Hardy Weinberg's II equation -  

p^{2} +2pq + q^{2} =1\\0.2234^2+2pq+0.6030=1\\2pq= 0.1736

Hence,  

The frequency of the dominant allele, C = 0.2234

and the heterozygous genotype, Cc= 0.1736
