PAG 10.1 Investigating DNA structure using RasMol Questions and Answers | Latest Update | 2024/2025 | Already Passed **Question:** How are the DNA chains oriented with respect to each other? **Answer:** The DNA chains are arranged in an antiparallel orientation. This means that within the DNA double helix, one strand runs in the 5' to 3' direction (one end to the other) while the complementary strand runs in the opposite direction, from 3' to 5'. This antiparallel arrangement ...

Introduction(+everything you need to know about breast imaging):  X-Rays was discovered by Wilhelm Conrad Röntgen on 8 November 1895.  Electromagnetic spectrum:  Photons that propagate in vacuum in straight lines at the speed of light; (Gamma ray → X-ray → Ultraviolet → Visible light → Infrared → Microwaves → Radio-waves)  X-rays:  Uses: 1. X-ray crystallography. 2. Mammography.  Produced by energy conversion in the X-ray tube.  A diagnostic image is c...
