Chapter 11: DNA and Genes: Chapter 11 Dna And Genes Answer Key
Chapter 11 explores the fundamental concepts of molecular genetics, focusing on the structure, function, and transmission of genetic material. It examines the molecular basis of heredity, the processes involved in gene expression, and the regulation of these processes.
Structure and Function of DNA
DNA, or deoxyribonucleic acid, is a double-stranded molecule that carries the genetic instructions for all living organisms. It consists of a sugar-phosphate backbone and nitrogenous bases (adenine, thymine, cytosine, and guanine) that pair up in a specific manner: A with T, and C with G.
The sequence of these bases along the DNA molecule determines the genetic code, which provides the instructions for building and maintaining an organism.
Processes of DNA Replication and Transcription, Chapter 11 dna and genes answer key
DNA replication is the process by which a cell makes an identical copy of its DNA before cell division. During replication, the DNA double helix unwinds, and each strand serves as a template for the synthesis of a new complementary strand.
Transcription is the process by which the genetic information in DNA is copied into a messenger RNA (mRNA) molecule. The mRNA molecule then carries the genetic code to the ribosomes, where proteins are synthesized.
Key Questions Answered
What is the structure of DNA?
DNA is a double helix composed of two strands of nucleotides, each consisting of a sugar molecule, a phosphate group, and a nitrogenous base (adenine, cytosine, guanine, or thymine).
How does DNA replication occur?
DNA replication is the process by which a cell makes an identical copy of its DNA. It involves unwinding the double helix, separating the strands, and synthesizing new complementary strands.
What is the role of RNA in protein synthesis?
RNA carries the genetic information from DNA to the ribosome, where it serves as a template for protein synthesis.
