Which of the DNA strands has its 3’ end on the left side? Image Long Description A diagram shows red lines on a white background with black text labels. At the top, there is a horizontal blue double-headed arrow with “Left” labeled on the left side and “Right” labeled on the right side. Below this are several red lines: two horizontal parallel lines on the left side, and two diagonal lines that angle upward toward the right side. Black arrows and letters mark specific points – “A” points down to the upper horizontal line, “B” points up to the lower horizontal line, “C” points to the lower diagonal line, and “D” points to the upper diagonal line.

Which of the following is deoxyribose? Image Long Description Three molecular diagrams arranged horizontally across the page. Each diagram is labeled at the top as “Molecule A,” “Molecule B,” and “Molecule C” in black text. Each molecule consists of a pentagon-shaped ring structure made of black lines, with an oxygen atom (O) at the top of each ring. Various chemical groups are attached to the rings: CH2OH groups appear at the top of each molecule, and OH (hydroxyl) and H (hydrogen) groups are positioned at different points around the bottom portions of the rings. The molecules appear to be structural chemical formulas drawn in black lines and text on a white background. Molecule A has OH groups at two bottom positions, Molecule B has one OH group and one H at the bottom positions, and Molecule C has two H groups at the bottom positions.

Which base will thymine (enol) pair with in DNA? Image Long Description Six molecular structure diagrams arranged in two rows. Each diagram consists of connected hexagonal and pentagonal rings with various atoms and bonds labeled with letters and symbols. In the top row from left to right: – An orange hexagonal ring labeled “Thymine (enol form)” with attached groups including CH₃, O-H, and other atoms – A cyan hexagonal ring labeled “a. Cytosine” with NH₂ and other attached groups – A yellow hexagonal ring labeled “b. Uracil” with H and O attachments – An orange hexagonal ring labeled “c. Thymine” with H₃C and other groups In the bottom row from left to right: – A blue double-ring structure labeled “d. Guanine” with NH₂ groups and other atoms – A green double-ring structure labeled “e. Adenine” with NH₂ and other attached groups All structures show carbon (C), nitrogen (N), hydrogen (H), and oxygen (O) atoms connected by lines representing chemical bonds. The rings are filled with solid colors while the connecting atoms and bonds are shown in black lines and text.

The genetic profile of the embryos in a population is indicated in the table below. Following natural selection, the deleterious phenotype disappears and only a portion of the population reaches adulthood. Think about the values needed to complete the table, this will help you find the values needed for this question and the following two. Image Long Description A table with two sections separated by a red arrow pointing downward and text reading “Natural selection occurs”. The top section is labeled “Embryos” and contains rows for “Number”, “Frequency”, and “Fitness” with columns labeled “AA”, “Aa”, “aa”, and “Total”. The Number row shows values 100, 200, 100, and 400. The Frequency row is empty. The Fitness row shows values 1, 0.75, 0, with the last cell shaded gray. The bottom section is labeled “Adult” and contains rows for “Number” with the same column headers “AA”, “Aa”, “aa”, and “Total”, but all cells in this section are empty. What is the frequency of allele A in the reproductive adults? Select the right answer and show your work on your scratch paper for credit.
