Which TWO children are the biological offspring of Cindy and George?

1.3.1 - 1.3.4 Match Column I to Column II 1.3.1 Produced the first X-ray image of the DNA molecule: A: Rosalind Franklin 1.3.2 Discovered the structure of DNA: B: Watson and Crick 1.3.3 Monomers of nucleic acids: B: Nucleotides 1.3.4 Replication takes place during: B: Interphase of cell division Add labels to the diagram A: Nitrogenous base* (specifically Adenine, but the pairing with G is atypical in this diagram) The pentagon structure: Deoxyribose sugar* (already labeled by student) C: Phosphate group* (already labeled by student) Bonds between bases: Weak hydrogen bonds* (already labeled by student) Give TWO observable reasons why this diagram represents a section of a DNA molecule It is double stranded*. It contains deoxyribose sugar*. Differences between DNA and RNA | DNA | RNA | | :------------------ | :------------------ | | Contains deoxyribose sugar | Contains ribose sugar | | Contains thymine as a base | Contains uracil as a base | | Double-stranded helix | Single-stranded (mostly) | | Stores genetic information | Involved in protein synthesis | Give THREE reasons why this diagram represents Replication The double helix is unwinding* and separating into two template strands. New nucleotides are pairing* with the exposed bases on each original strand. Two new daughter DNA molecules* are being synthesized, each containing one original and one new strand. Significance of DNA replication DNA replication is important because: It ensures that each daughter cell receives a complete and identical set of genetic information* during cell division. It allows for growth, repair, and reproduction* in organisms. DNA profiling It can be described as a technique used to identify individuals by analyzing unique patterns in their DNA. Every person except identical twins has her/his own unique DNA profile. DNA profiling can be controversial because: It raises concerns about privacy and the security* of genetic information. There is a potential for misinterpretation or misuse* of DNA evidence in legal or social contexts. Which TWO children are the biological offspring of Cindy and George? Sipho and Glenda Reason: All the DNA bands present in Sipho's and Glenda's profiles can be matched to either Cindy's or George's profile, indicating they inherited their DNA from these parents. Other uses of DNA profiling Paternity testing* to determine biological parentage. Forensic investigations* to identify suspects or victims at crime scenes. Drop the next question! 📸
