The hardy-weinberg equation is useful for predicting the percent of a human population that may be heterozygous carriers of recessive alleles for certain genetic diseases. phenylketonuria (pku) is a human metabolic disorder that results in intellectual disabilities if it is untreated in infancy. if the u. s. population is in hardy-weinberg equilibrium, approximately what percent of the population are heterozygous carriers of the recessive pku allele?

1.98% or 2%

Explanation:

In US, 1 out of 10000 people has the disease. So, the frequency of the recessive alleles is 1/10000 = 0.0001

This term is q^2, so now we need to find the q term alone. q= = 0.01

Now, as p+q=1 in HW equations, then p=1-q, in this case p=1-0.01=0.99

So, the next part is determine what percentage is the heterozygous carriers and the heterozigous are in the equation named as 2pq

2pq=> 2(0.01)*(0.99)=0.0198 If we convert it to percentage is 0.0198 * 100= 1.98% aproximate to 2%

step 1: initiation

initiation is the beginning of transcription. it occurs when the enzyme rna polymerase binds to a region of a gene called the promoter. this signals the dna to unwind so the enzyme can ‘‘read’’ the bases in one of the dna strands. the enzyme is now ready to make a strand of mrna with a complementary sequence of bases.

step 2: elongation

elongation is the addition of nucleotides to the mrna strand. rna polymerase reads the unwound dna strand and builds the mrna molecule, using complementary base pairs. there is a brief time during this process when the newly formed rna is bound to the unwound dna. during this process, an adenine (a) in the dna binds to an uracil (u) in the rna.

step 3: termination

termination is the ending of transcription, and occurs when rna polymerase crosses a stop (termination) sequence in the gene. the mrna strand is complete, and it detaches from dna.

photosynthesis makes the glucose that is used in cellular respiration to make atp. the glucose is then turned back into carbon dioxide, which is used in photosynthesis. while water is broken down to form oxygen during photosynthesis, in cellular respiration oxygen is combined with hydrogen to form water.
