Question

Fill in the missing base pairs of the DNA with capital letters in the strands below. Color the parts with colored pencils using the key below. guanine =red sugar - purple thymine = green adenine = yellow cytosine blue phospate pink

Answer 1

Students must use complementary base pairing rules of DNA to fill in missing bases and color code them accordingly – adenine (yellow) pairs with thymine (green), and cytosine (blue) pairs with guanine (red).

Step-by-step explanation:

The student's task is to fill in the missing base pairs of a DNA strand using the information about DNA's structure provided by Watson and Crick. According to their model, adenine (A) pairs with thymine (T) and cytosine (C) pairs with guanine (G), forming complementary base pairs. For example, if the given DNA strand has a sequence of AGTGCCT, the complementary strand would be TCACGGA. It is important to use the designated colors for each base as per the key provided: guanine (G) in red, adenine (A) in yellow, thymine (T) in green, cytosine (C) in blue, phosphate in pink, and sugar in purple.
