Chapter 8 - Genes to Proteins Flashcards
Proteins
A macromolecule made up of repeating subunits called amino acids, which determine the shape and function. Play many critical roles in living organisms
Amino Acids
The building blocks of proteins
Gene
A sequence of DNA that contains the information to make at least one protein
Gene Expression
The process of using DNA instruction as to make proteins
regulatory sequence
The part of a gene that determines the timing, amount, and location of protein production
Coding sequence
The part of a gene that specifies the amino acid sequence of a protein. determine the identity, shape, and function of proteins
Transcription
The first stage of gene expression, during which cells produce molecules of messenger RNA (mRNA) from the instructions encoded within genes in DNA
Messenger RNA(mRNA)
The RNA copy of an original DNA sequence made during transcription
Translation
The second stage of gene expression, during which mRNA sequences are used to assemble the corresponding amino acids to make a protein
RNA polymerase
The enzyme that carries out transcription, copies a strand of DNA into a complementary strand of mRNA
Ribosome
The cellular machinery that assembles proteins during translation
Codon
A sequence of three mRNA nucleotides that specifies a particular amino acid
transfer RNA (tRNA)
A type of RNA that transports amino acids to the ribosome during translation
anticodon
The part of a tRNA molecule that binds to a complementary mRNA codon
Genetic code
The set of rules relating particular mRNA codons to particular amino acids
transgenic
refers to an organism that carries one or more genes from a different species
recombinant gene
a genetically engineered gene that contains portions of genes not naturally found together
genetic engineering
altering of manipulating the DNA of organisms by modern laboratory techniques
Vector
A DNA molecule used to deliver a recombinant gene to a host cell
genetically modified organisms (GMOs)
An organism whose genome has been altered through genetic engineering techniques, often to contain a gene from another species.
Gene Therapy
A treatment that aims to cure, treat, or prevent human disease by replacing defective genes with functional ones
Amino Acids all have the same…
Basic core structure
What is unique on each amino acid?
chemical side group
What shape do amino acids fold into? What is the base of the structure?
