How is the PCR product separated from the PCR mixture at the completion of the reaction? A. Perform electrophoresis in an agarose gel, stain the gel and cut the band corresponding to the PCR product from the gel. B. Pour the PCR mixture into a commercially prepared DNA microconcentrator column and follow the manufacturer's directions to adhere and elute the PCR product from the column. C. Both of the above procedures may be used. D. Neither of the above procedures may be used.

The two suggested processes such as gel electrophoresis and micro concentrator column are applied. Therefore, choice C is right.

A specific piece of DNA can be quickly produced (amplified) in millions or billions of copies using the polymerase chain reaction, or PCR. It uses visual approaches based on size and charge to detect and identify gene sequences. The products of PCR are nothing but billion and millions of copies of target DNA or gene.

These genes are visualized by two techniques. One technique is agarose gel electrophoresis and another technique is the use of a micro concentrator column.

In agarose gel electrophoresis, the DNA samples are prepared and poured into the well. Then, they are separated based on size and charge using an electric field. Negatively charged DNA strands run toward the positive electrode and the smaller fragments run faster. In the micro concentrator column, the PCR products are poured according to the manual description and purified.

A new human species was found on a distant planet, whose genetic inheritance and process of reproduction is identical to that of humans on earth, however, their phenotypes are much different. You are tracking two phenotypes in this new species: eye shape and tail size. The single gene that controls eye shape (gene E) is unlinked from the single gene that controls tail size (gene T). Square eyes is the dominant eye shape and round eyes is the recessive eye shape. Long tail is the dominant tail size and short tail is the recessive tail size.

Required:
An individual of this new species is heterozygous for gene E and heterozygous for gene T. What is their genotype and phenotype?

Enzymes can be regulated in a multitude of ways. One such way is by covalent modification, in which functional groups are attached to or removed from the enzyme. One such functional group that can be added to an enzyme is a phosphate group. Depending on the enzyme, addition of a phosphate group may increase or decrease that enzyme's activity. Which of the following is the general name of an enzyme that functions to add phosphate groups to its substrate?

a. Oxidoreductases
b. Ligases
c. Hydrolases
d. Isomerases
e. Transferases

1): Lily is dressing up as a chicken for Halloween this year and is flapping her arms like a bird as she walks from house to house. As Lily flaps her arms down to her sides, what type of movement is occurring?

2): Katie loves pretending that she’s a human cannonball. As she jumps off the diving board, she assumes the proper position before she pounds into the water: head and thighs tucked against her chest; back rounded; arms pressed against her sides while her forearms, crossed in front of her shins, hold her legs tightly folded against her chest. What movement term would best describe the positioning of Katie’s vertebral column, head, thighs, lower legs and lower arms? HINT: She is about as far from the anatomical position as she can get.
