Draw the Polynucleotide Strand in Figure 5

question 15

Essay

Draw the polynucleotide strand in Figure 5.27a from your textbook, and label the bases G, T, C, and T, starting from the 5' end. Now, draw the complementary strand of the double helix, using the same symbols for phosphates (circles), sugars (pentagons), and bases. Label the bases. Draw arrows showing the 5' → 3' direction of each strand. Use the arrows to make sure the second strand is antiparallel to the first. Hint: After you draw the first strand vertically, turn the paper upside down; it is easier to draw the second strand from the 5' toward the 3' direction as you go from top to bottom.

Definitions:

Positive Autocorrelation

Occurs when a variable's current value is positively related to its past values in a time series.

Durbin-Watson Statistic

A statistical measure employed to identify if there is autocorrelation at the first lag within the residual values following a regression analysis.

Positive Autocorrelation

A situation in which the errors in a regression model are positively correlated, meaning that a positive error in one period is likely to be followed by a positive error in the next.

Multicollinearity

A situation in regression analysis where independent variables are highly correlated, making it difficult to estimate individual regression coefficients accurately.
