DNA Sequencing:
Definition: The process of determining the order of nucleotides in a DNA molecule.
Human Genome Project:
Definition: A research project that aimed to map and understand the human genome.
Amino Acids:
Definition: The building blocks of proteins.
Genetic Code:
Definition: The set of rules by which information in DNA is translated into proteins.
Gene Expression:
Definition: The process by which information from a gene is used to synthesize a functional gene product.
Transcription:
Definition: The process of synthesizing mRNA from a DNA template.
Messenger RNA (mRNA):
Definition: The type of RNA that carries genetic information from DNA to the ribosome.
Transfer RNA (tRNA):
Definition: The type of RNA that carries amino acids to the ribosome during protein synthesis.
Translation:
Definition: The process of synthesizing proteins from mRNA.
Codon:
Definition: A sequence of three nucleotides that codes for a specific amino acid or signals the end of protein synthesis.
RNA Polymerase:
Definition: An enzyme that synthesizes RNA from a DNA template during transcription.
Promoter:
Definition: A specific sequence of DNA that initiates transcription.
Anticodon:
Definition: A sequence of three nucleotides on tRNA that is complementary to a codon on mRNA.
Ribosomal RNA (rRNA):
Definition: The type of RNA that forms part of the ribosome and facilitates protein synthesis.
Genomics:
Definition: The study of entire genomes, including genes and non-coding sequences.
Proteomics:
Definition: The study of the structure and function of proteins.
Mutation:
Definition: A change in the nucleotide sequence of DNA.
Somatic Cell Mutation:
Definition: A mutation occurring in a body cell, not passed on to offspring.
Germline Mutation:
Definition: A mutation occurring in the cells that give rise to gametes and can be passed to offspring.
Point Mutation:
Definition: A mutation involving a change in a single nucleotide.
Silent Mutation:
Definition: A mutation that does not result in a change to the amino acid sequence of a protein.
Mis-sense Mutation:
Definition: A mutation that changes one amino acid in a protein sequence.
Nonsense Mutation:
Definition: A mutation that results in an early stop codon, leading to premature termination of protein synthesis.
Frameshift Mutation:
Definition: A mutation caused by the insertion or deletion of nucleotides, shifting the reading frame.
Mutagen:
Definition: An agent that causes mutations.
