Genetics Introduction

Front

What is a gene?

Back

A gene is a piece of DNA that contains the instructions for building and maintaining an organism's cells, tissues, and organs.

Front

What does it mean for a trait to be dominant?

Back

A dominant trait is one that is expressed or shown in the phenotype even when only one copy of the gene is present.

Front

Why is DNA considered the blueprint of life?

Back

DNA serves as the blueprint for traits of all living things, containing the genetic instructions necessary for the development and functioning of organisms.

Front

What is heredity?

Back

Heredity is the passing of traits from one parent to offspring.

Front

What is a chromosome?

Back

A chromosome is a tightly wound bundle of DNA that contains many genes.

Front

What is the role of alleles in genetics?

Back

Alleles are different versions of a gene that can result in different traits.

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

What is a mutation?

Back

A mutation is a change in the DNA sequence that can lead to variations in traits.

Front

What is the significance of the double helix structure of DNA?

Back

The double helix structure of DNA allows for the stable storage of genetic information and the accurate replication of DNA during cell division.

Front

What is the function of ribosomes in protein synthesis?

Back

Ribosomes are the cellular structures where proteins are synthesized by translating messenger RNA (mRNA) into amino acid sequences.
