If a portion of strand of DNA bases reads 5’ AGCTAGCGT 3’, what would the sequence of bases on the complementary strand read?

A. 5’ UCGAUCGCA 3’

B. 3’ TCGATCGCA 5’

C. 5’ TCGUTCGCU 3’

D. 3’ AGCTAGCGT 5’

Answer Explanation:

The complimentary base pairing of DNA states that A pairs with T while C pairs with G. From the give sequence, the complimentary DNA strand will be 3’ TCGATCGCA 5’

Therefore, the Correct Answer is B.

Q #1: In a certain plant, red flowers are dominant over white flowers. A plant heterozygous for red flowers and a plant with white flowers are crossed. Which of the following is the expected proportion of phenotypes in the next generation?

A. 3 red, 1 white

B. 1 white, 3 red

C. 2 red, 2 white

D. 4 white

Answer Explanation

2 red, 2 white.

In this cross, the plant heterozygous for red flowers has the genotype Rr (where R represents the dominant red allele and r represents the recessive white allele), while the plant with white flowers has the genotype rr.

The possible offspring from this cross would have the genotypes Rr (red), Rr (red), rr (white), and rr (white), resulting in a 1:1 ratio of red to white flowers.
Q #2: Which of the following are structural features of the trachea?

A. C-shaped cartilage

B. Smooth muscle fibers

C. Cilia

D. All of the above

Answer Explanation
Q #3: Which of the following processes causes most of the carbon dioxide from the blood to move into the alveoli?

A. Diffusion down a concentration gradient

B. Conversion of carbon monoxide

C. Passive transport using carrier proteins

D. Active transport using energy

Answer Explanation

Carbon dioxide moves from the blood to the alveoli through the process of diffusion. The blood has a high concentration of carbon dioxide than the alveoli.
Therefore, carbon dioxide diffuses from blood to alveoli through the cell membrane.
