Differences Between DNA and RNA, DNA Replication, and Protein Synthesis

These flashcards cover key concepts related to DNA and RNA differences, DNA replication, and the process of protein synthesis.

Where is DNA found in a cell?

In the nucleus, chloroplast, and mitochondria.

What is the structure of DNA compared to RNA?

DNA is a double stranded molecule, while RNA is a single stranded molecule.

What sugar is contained in RNA?

Ribose.

What is DNA replication?

The process by which DNA makes an identical copy of itself.

When does DNA replication occur?

Just before cell division during interphase.

Why is DNA replication important?

It ensures that each daughter cell has the same number of chromosomes as the original cell.

What is the result of DNA replication?

Two genetically identical DNA molecules.

What is a DNA profile?

Patterns of black bars left on X-ray film when DNA is analyzed.

What are some uses of DNA profiles?

Diagnosis of inherited disorders, criminal identification, and establishing familial relationships.

What are the controversies surrounding DNA profiling?

Issues include potential non-uniqueness, lab standard inconsistencies, human error, cost, and privacy concerns.
