Bioinformatics
This field combines biology, computer science, and mathematics to analyze and interpret biological data. It plays a crucial role in understanding genetic information and developing new medical treatments.
C
CRISPR-Cas9
This is a powerful tool used in genetics that allows scientists to edit DNA with precision. It can modify genes in living organisms, making it possible to correct genetic defects or enhance certain traits.
C
Chromatin
It is a complex of DNA and proteins found in the nucleus of cells. Chromatin helps package DNA into a compact structure, making it possible for cells to efficiently manage genetic information.
C
Copy Number Variation
It refers to variations in the number of copies of a particular gene or genomic region in a person's DNA. These variations can affect how genes function and contribute to differences in traits and susceptibility to diseases.
D
Deletion / Insertion
Deletion and insertion refer to genetic mutations where segments of DNA are either removed (deletion) or added (insertion). These changes can significantly affect how genes function and can lead to various genetic disorders or traits.
D
Dominant / Recessive
In genetics, dominant and recessive refer to how traits are inherited from parents to offspring. A dominant trait can overshadow a recessive trait, meaning that if an individual has one dominant allele, that trait will be expressed.
E
Enhancer
An enhancer is a short region of DNA that helps to increase the likelihood of transcription of a particular gene. By interacting with proteins called transcription factors, enhancers can boost gene expression, playing a crucial role in regulating how genes are turned on or off.
E
Exon / Intron
An exon is a segment of a gene that contains coding information for protein synthesis, while an intron is a non-coding segment that is removed during the process of gene expression. Together, they play a crucial role in how genes are expressed and how proteins are made in living organisms.
G
GWAS (Genome-Wide Association Study)
A Genome-Wide Association Study (GWAS) is a research approach used to identify genetic variants linked to specific diseases or traits. It examines the entire genome of many individuals to find common genetic factors that may contribute to health conditions.
G
Gel Electrophoresis
A method used to separate and analyze DNA, RNA, or proteins based on their size and charge. It involves applying an electric field to a gel, causing the molecules to move and form distinct bands.
G
Gene Editing
Gene editing is a scientific technique that allows scientists to alter the DNA of an organism. This process can involve adding, removing, or changing specific sections of DNA to achieve desired traits or eliminate genetic disorders.
G
Gene Expression
It is the process by which information from a gene is used to create a functional product, typically a protein. This process is essential for the growth, development, and functioning of all living organisms.
G
Gene Therapy
A method used to treat or prevent diseases by altering the genes inside a person's cells. It aims to fix or replace faulty genes that cause illness, potentially leading to cures for genetic disorders.
G
Genotype
A genotype is the genetic makeup of an organism, specifically the set of genes it carries. It determines various traits and characteristics, such as eye color or disease susceptibility.
H
Heritability
Heritability is a measure of how much of a trait's variation in a population can be attributed to genetic differences among individuals. It helps us understand the role genetics plays in traits like height, intelligence, and susceptibility to diseases.
H
Histone
A histone is a type of protein that helps package and organize DNA in the cells of living organisms. They play a crucial role in gene regulation and the overall structure of chromosomes.
I
Inheritance Pattern
An inheritance pattern describes how traits or characteristics are passed from parents to their offspring. It helps us understand the genetic mechanisms behind the transmission of traits, which can be influenced by various factors.
M
Mendelian Genetics
Mendelian Genetics is the study of how traits are inherited from one generation to the next based on the principles established by Gregor Mendel. It focuses on the role of individual genes and their variations in determining specific characteristics in organisms.
M
Methylation
Methylation is a chemical process where a methyl group is added to DNA. This process can affect how genes are turned on or off, influencing various biological functions.
N
Non-Coding RNA
Non-coding RNA refers to RNA molecules that do not encode proteins but play crucial roles in regulating gene expression and maintaining cellular functions. These molecules are essential for various biological processes, despite not being translated into proteins.
P
PCR (Polymerase Chain Reaction)
Polymerase Chain Reaction (PCR) is a technique used to make millions of copies of a specific DNA segment. It allows scientists to amplify small amounts of DNA for analysis and research.
P
Pharmacogenomics
Pharmacogenomics is the study of how a person's genes affect their response to medications. It aims to tailor drug treatments to individuals based on their genetic makeup, improving effectiveness and reducing side effects.
P
Phenotype
A phenotype is the observable physical and functional traits of an organism, such as its appearance, behavior, and biochemical properties. These traits result from the interaction of an organism's genetic makeup and its environment.
P
Point Mutation
A point mutation is a change in a single nucleotide in the DNA sequence. This small alteration can affect how genes function and can lead to various genetic disorders or traits.
