Let's make the alleles Tt, where T is dominant (tongue rolling) and t is recessive (inability to tongue roll).
The heterozygous tongue roller would be Tt and the non tongue roller would be tt. Putting them in a punnet square (refer to attachment), the chances that their child will be a non tongue roller would be a 50% chance.
Tt: 2/4 = 50%
tt: 2/4 = 50%
Answer:
It is associated with a sliding clamp only on the leading strand.
Explanation:
DNA polymerase must exhibit higher processivity for an efficient DNA replication process. The processivity is imparted by some specific subunits such as the beta subunit of DNA polymerase III. These subunits form a sliding clamp to allow the DNA polymerase to add a large number of nucleotides to the primer before detaching from the template.
Four copies of beta subunits of DNA polymerase III form a donuts shaped structure around each template strand of DNA and serve as a clamp. Each pair of beta subunits associated with core DNA polymerase. The function of these sub-units is to slide along DNA as replication processed. The sliding clamp does not allow the dissociation of DNA polymerase frequently and allows efficient replication of both leading and lagging strands.
Answer;
D. controlled
An experiment in which only one variable is changed is a controlled experiment.
Explanation;
-A control experiment is an experiment where the researcher only changes one variable at a time in order to isolate the results.
In a controlled experiment, most conditions are constrained so that they do not change. One or two other conditions are then changed and measured by the experimenter. These are known as the independent variables.
For example; An experiment where all subjects involved in the experiment are treated exactly the same except for one deviation.
When the carbon dioxide from animal respiration is released it goes into the atmosphere
Answer:
Friedreich ataxia is inherited in an autosomal recessive manner.
Explanation:
Autosomal recessive disorder is a type of disorder which occurs only when abnormal genes are present in both cells. Autosomal recessive is a method through which disease is passed from parents to offspring. Friedreich's ataxia is a genetic disease that is very rare which causes difficultly in movement from one place to another, a loss of sensation in the arms and legs, and speech in the patients.
