question 25

Multiple Choice

The main difference between therapeutic cloning and reproductive cloning is that

• A)in therapeutic cloning,embryonic stem cells are extracted from the blastocyst,while in reproductive cloning,the blastocyst is kept intact and implanted into a surrogate mother.
• B)somatic cell nuclear transfer is used for therapeutic cloning,while gametic cell nuclear transfer is used in reproductive cloning,the blastocyst is kept intact and implanted into a surrogate mother.
• C)unlike cells used for reproductive cloning,cells grown for therapeutic purposes do not display genetic imprinting problems.
• D)unlike cells used for reproductive cloning,cells grown for therapeutic purposes do not require the destruction of embryos.

Definitions:

Goodness of Fit

A statistical test used to determine how well observed data match the expected data from a model.

Estimated Regression Equation

The estimate of the regression equation developed from sample data by using the least squares method. For simple linear regression, the estimated regression equation is yˆ = b0 + b1x.

Multicollinearity

A statistical phenomenon in which two or more predictor variables in a multiple regression model are highly correlated, making it difficult to distinguish their individual effects on the dependent variable.

Independent Variables

Variables in an experiment or statistical model that are manipulated or categorized to determine their effect on dependent variables.
