chapter 8part 1

What is the study of genes, how they carry information, how information is expressed, and how genes are replicated called?

• Chromosomes

• Genes

• Genetics

• Genome

What are chromosomes?

• All the genetic information in a cell

• Segments of DNA that encode functional products

• Structures containing DNA that physically carry hereditary information and contain genes

• The study of hereditary information

What do genes encode?

• The entire structure of DNA

• Functional products, usually proteins

• The study of hereditary information

• The physical structure of chromosomes

What does the term 'genome' refer to?

• The study of genes and their functions

• The structure that carries hereditary information

• Segments of DNA that encode functional products

• All the genetic information in a cell

What is the genetic code?

• A type of DNA sequence

• A set of rules that determines how a nucleotide sequence is converted to an amino acid sequence of a protein

• A model of DNA replication

• A sequence of sugars and phosphates

What is the central dogma of molecular biology?

• DNA is transcribed to RNA, which is then translated to Protein

• Proteins are synthesized directly from DNA without RNA

• RNA replicates to form DNA, which then forms Proteins

• DNA is translated to RNA, which is then transcribed to Protein

What is the definition of Genotype?

• Expression of the genes

• The genetic makeup of an organism

• A type of genetic mutation

• The physical appearance of an organism

What does Phenotype refer to?

• The genetic makeup of an organism

• A type of genetic mutation

• Expression of the genes

• The classification of organisms

What shape is the chromosome that bacteria usually have?

• Linear

• Circular

• Triangular

• Hexagonal

What are short tandem repeats (STRs)?

• Enzymes that cut DNA

• Proteins that bind to DNA

• Repeating sequences of noncoding DNA

• Genes that code for structural proteins
