Chargaff's rules of base pairing helped scientists determine how DNA replication occurs. What property of the replication process is explained by Chargaff's rules? A. The phosphate-sugar backbone of one strand serves as a template for the phosphate- sugar backbone of the complementary strand.

B. The phosphate-sugar backbone of one strand serves as a template for the sequence of four nucleotides in the complementary strand.

C. Adenine (A) and thymine (1) are always paired together within a single DNA strand, as are cytosine (C) and guanine (G).

D. Adenine (A) and thymine (1) always bind to each other across complementary strands, as do cytosine (C) and guanine (G).​

This part insulates the reaction chamber from the transfer of heat to or from the surrounding environment

Which statements best describe the differences or similarities between a comparative investigation and an experimental investigation? check all that apply. experimental investigations are best for showing cause-and-effect relationships, while comparative investigations do not necessarily show this type of relationship. comparative investigations are often impractical and unrealistic, while experimental investigations are the most practical and realistic kinds of investigations. comparative investigations allow for the use of a wide range of variables but do not have a control group, while experimental investigations involve variables that can be controlled. both experimental investigations and comparative investigations are designed to answer scientific questions. both experimental investigations and comparative investigations focus on making observations rather than collecting new data.

What are the three different shapes, or structures, of carbon-based molecules
