Rosalind Franklin and Maurice Wilkins conducted experiments using X-ray crystallography to study the structure of the DNA. Their experiments produced the famous photo 51, the first evidence on the structure of the DNA. Their work showed that DNA is double-stranded and forming a helix. They also showed that the nitrogenous bases are on the inside of the strands and that the phosphates are on the outside. Watson and Crick used these observations to develop their model on the molecular structure of the DNA.

In guinea pigs hair straightness or curliness is thought to be governed by a single pair of alleles showing incomplete dominance
Nimfa-mama [501]

Answer:

Frequency of allele S is p = 0.4939

Frequency of allele C is q = 0.666

The population is not in Hardy-Weinberg equilibrium

Explanation:

Given -

Number of individuals with straight hair = 244

Number of individuals with curly hair = 444

Number of individuals with Wavy hair = 312

Let "p" represents the frequency for allele for straight hair and "q" represents the frequency for allele for curly hair

p^2 represents the frequency of genotype "SS"

p^{2} = \frac{244}{1000} \\= 0.244

q^2 represents the frequency of genotype "CC"

p^{2} = \frac{444}{1000} \\= 0.444

2pq represents the frequency of genotype "SC"

2pq = \frac{312}{1000} \\= 0.312

Frequency of allele S is p

= \sqrt{0.244} \\= 0.4939

Frequency of allele C is q

tex]= \sqrt{0.444} \\= 0.666[/tex]

For being in Hardy Weinberg's equation-

p+q=1\\

Substituting the values in above equation, we get -

0.4939+0.666\neq 1

hence, the population is not in Hardy-Weinberg equilibrium

What happen to water during hydrolysis?
hammer [34]
<span>In a hydrolysis reaction, water (H2O) is added to a bond and cleaves the bond holding molecules together, breaking polymers into 2 pieces. In total, you take a water molecule and split it among the two parts, H+ and OH-. These ions get added to either side with the higher affinity for the cation (H+) and anion (OH-). </span>

How is the carbon dioxide produced by humans during respiration?
nexus9112 [7]
During aerobic respiration, complete oxidation of carbohydrates takes place. Glucose is broken down by oxygen to release energy, while carbon dioxide and water are the by-products of the reaction. The released energy is used to make a special energy molecule called Adenosine triphosphate (ATP).
