Genes and Molecular Machines Lesson 1 Study Guide

Front

What is a gene?

Back

A gene is a segment of DNA that contains the instructions for building proteins, which determine the traits of an organism.

Front

What is the role of genes in determining traits?

Back

Genes control the expression of traits in an organism by providing the instructions for protein synthesis.

Front

What is genetic inheritance?

Back

Genetic inheritance is the process by which traits and characteristics are passed from parents to offspring through genes.

Front

What is a trait?

Back

A trait is a specific characteristic or feature of an organism, such as eye color or height, that is influenced by genes.

Front

What is genetic manipulation?

Back

Genetic manipulation is the process of altering the genetic material of an organism to achieve desired traits, such as pest resistance in crops.

Front

What is a cell?

Back

A cell is the basic unit of life in all living organisms, serving as the building block for tissues and organs.

Front

What is the difference between genotype and phenotype?

Back

Genotype refers to the genetic makeup of an organism, while phenotype refers to the observable traits or characteristics.

Front

How do environmental factors influence traits?

Back

Environmental factors can affect the expression of traits by interacting with an organism's genetic makeup.

Front

What is the significance of genetic diversity?

Back

Genetic diversity is important for the survival of species, as it allows for adaptation to changing environments.

Front

What is a mutation?

Back

A mutation is a change in the DNA sequence of a gene, which can lead to changes in traits.
