UNIT 2; NATURAL SELECTION AND GENETICS Flashcards
(30 cards)
Gene Mutations
Substitution (Point), Insertion (Frameshift), Deletion (Frameshift)
Chromosome Mutations
Duplication, Deletion, Inversion, Translocation
Substitution (Point)
It is when a base is put in place of another base to substitute it.
Insertion (Frameshift)
It is when a base is added when it is not supposed to be there.
Deletion (Frameshift)
It is when a base is taken away or deleted from its original place.
Duplication
It is when extra copies of genes are generated.
Deletion
It is when nucleotides are lost from a segment of DNA.
Inversion
It is when genes are reversed or the order of the genes are switched.
Translocation
It is when a piece of chromosome attaches itself to a different chromosome.
Order of size for DNA, chromosome, nucleotide, gene
Chromosome, gene, DNA, nucleotide
What are proteins made of?
Proteins are made of long chains of building blocks called amino acids.
What is the purpose of proteins?
The purpose of proteins is to carry out most of the bodyś functions and to make up the bulk of its structure– such as fingernails and muscle.
What is a gene?
A gene is a large unit made up with the 4 building blocks that are also a set of instructions for building a specific protein.
What are genes made up of?
Genes are made up of long segments of DNA.
What is a genome?
A genome is a complete set of genes, or a set of instructions for building an entire organism.
What is the purpose of genes?
The purpose of genes is to give instructions on how to build a specific protein.
What are amino acids?
Amino acids are molecules that combine to form proteins
20-letter code of amino acids
the building blocks of proteins.
What is the relationship between genes and amino acids?
Protein-encoding genes specify the sequences of amino acids
What the main function of chromosomes?
The main function of chromosomes is to carry the DNA and transfer the genetic information from parents to offspring.
Chromosomes
threadlike structures made of protein and a single molecule of DNA that serve to carry the genomic information from cell to cell
