A strand of DNA bases reads 5' AGCTAGCGT 3, what would the sequence of bases on the contemporary strand read?

A. 3' STOGUTCGCU

B. 5' AGCTAGCGT S

C. 3' SUCGAUCICA

D. 3' TCGATCGCA 5'

Answer Explanation:

The complementary strand of DNA is formed by pairing complementary bases. In DNA, adenine (A) pairs with thymine (T), and guanine (G) pairs with cytosine (C). Additionally, RNA uses uracil (U) instead of thymine.

Given the sequence 5' AGCTAGCGT 3', the complementary strand would read:

3' TCGATCGCA 5'

Therefore, the Correct Answer is D.

Q #1: The hip is an example of which of the following type of joints?

A. Ball-and-socket

B. Pivot

C. Gliding

D. Hinge

Answer Explanation

The hip joint is an example of a ball-and-socket joint. The hip joint is formed by the articulation of the head of the femur with the acetabulum of the pelvis. The rounded head of the femur (ball) fits into the cup-shaped acetabulum (socket), allowing for a wide range of motion in multiple planes.
Q #2: Which of the following is correct regarding the pH scale?

A. A substance with a pH of 3 is two times more alkaline than a substance with a pH of 4

B. A substance with a pH of 3 is 10 times more acidic than a substance with a pH of 4

C. A substance with a pH of 3 is two times more acidic than a substance with a pH of 4

D. A substance with pH of 3 is 10 times more alkaline than a substance with a pH of 4

Answer Explanation

The pH scale is logarithmic, indicating that each whole number change on the pH scale represents a tenfold change in acidity or alkalinity. Therefore, a substance with a pH of 3 is 10 times more acidic than a substance with a pH of 4.
Q #3: A strand of DNA bases reads 5' AGCTAGCGT 3, what would the sequence of bases on the contemporary strand read?

A. 3' STOGUTCGCU

B. 5' AGCTAGCGT S

C. 3' SUCGAUCICA

D. 3' TCGATCGCA 5'

Answer Explanation

The complementary strand of DNA is formed by pairing complementary bases. In DNA, adenine (A) pairs with thymine (T), and guanine (G) pairs with cytosine (C). Additionally, RNA uses uracil (U) instead of thymine.

Given the sequence 5' AGCTAGCGT 3', the complementary strand would read:

3' TCGATCGCA 5'
