If a portion of a strand of DNA bases reads 5' AGCTAGCGT 3', what would the sequence of bases on the complementary strand read?
3' TCGATCGCA 5'
3' TCGUTCGCU 5'
3' AGCTAGCGT 5'
5' SucGAUCGCA 3'
The Correct Answer is A
The sequence of bases on the complementary strand of DNA would read 5' TCGATCGCA 3'. In DNA, the nitrogenous bases adenine (A) and thymine (T) pair together, and cytosine (C) and guanine (G) pair together. The complementary strand is also antiparallel to the original strand, meaning that it runs in the opposite direction with the 5' end matching up with the 3' end of the original strand. The other options do not accurately represent the complementary sequence of bases or the antiparallel orientation of the strands.

Explanation
Soap’s dual polar and nonpolar nature helps bond oil and water. Soap is an emulsifier, which means that it has both polar and nonpolar regions. The polar regions of soap molecules are attracted to water, while the nonpolar regions are attracted to oil and grease. This allows soap to bond with both water and oil, helping to remove dirt and grime from surfaces.
B. Soap’s acidity does not cause grime to precipitate into the water.
C. Soap does not have enzymatic action that helps to dissolve grime into small particles.
D. Soap’s texture does not physically scour grime off surfaces.
Correct Answer is A
Explanation
Nuclei. Genetic information describing the characteristics of an organism is found in the nuclei of its cells. The nucleus contains the organism's DNA, which carries the genetic information that determines its traits.
B. Membranes are structures that surround and enclose cells and organelles, but they do not contain genetic information.
C. Cilia are hair-like structures that protrude from the surface of some cells and are involved in movement, but they do not contain genetic information.
D. Ribosomes are organelles that are involved in protein synthesis, but they do not contain genetic information.
