Chapter 11 DNA Flashcards
The shape of two strands twisted together
Double helix
A carbon ring structure that contains one or more atoms of nitrogen
Nitrogen base
The process in which DNA in the chromosomes is copied
DNA replication
Brings information from the DNA in the nucleus to the cell’s factory floor, the cytoplasm
Messenger RNA
Ribosomes made up of —– clamp onto the mRNA and use it’s information to assemble the amino acids in the correct order
Ribosomal RNA
Transports amino acids to the ribosome to be assembled into a protein
Transfer RNA
The process in which enzymes make an RNA copy of a portion of a DNA strand
Transcription
The name for each set or three nitrogen bases in mRNA coding for an amino acid
Codon
The process of converting the information in a sequence of nitrogen bases in mRNA into a sequence of amino acids that make up a protein
Translation
Any change in the DNA sequence that also changes the protein it codes for
Mutation
A change in a single base pair in DNA
Point mutation
A mutation in which a single base is added or deleted from DNA
Frameshift mutation
Changes in chromosomes
Chromosomal mutations
Any agent that can cause a change in DNA
Mutagen
