Answer:

The correct answer would be option D.

mRNA is formed after transcription of the DNA.  

It carries the nucleotide sequence of the DNA to the ribosome in the form of codon sequence for translation, that is, the formation of the polypeptide chain.

The codon sequence of the mRNA codes for the amino acid sequence of the protein.

Given a population of 100 individuals where 15 are AA, 25 are Aa, and 60 are aa, what is
nata0808 [166]

Answer:

frequency of allele “A” is .39

frequency of allele “a” is .77

Explanation:

hardy weinberg equation

p^2 + 2pq + q^2 = 1 or (A+a)^2

p^2 =  (AA)

2pq =  (Aa)

q^2 = (aa)

AA -> 15/100 = .15

Aa -> 25/100 = .25

aa -> 60/100 = .60

if p^2 = AA = .15 then A = √.15 = 0.38729833462 = .39

if q^2 = aa = .60 then a = √.60 = 0.77459666924 = .77

Which of the following has the fewest taste receptors?
kolbaska11 [484]

Answer:

filiform papillae

Explanation:

The filiform papillae, also called conical papillae, are sensory receptors distributed on two thirds of the lingual dorsum. They are the most abundant papillae on the surface of the tongue and are not associated with taste reception because they have the smallest number of taste receptors.

These papillae are arranged fairly evenly in rows parallel to the central groove of the tongue, especially in the center and back. These papillae are made up of connective tissue and an epithelium that expresses keratin, a protein present in people's skin, hair and nails.
