any factor which causes a mutation is called a
mutagen
a gene mutation where one nucleotide is replaced by a different nucleotide
substitution
DNA and RNA are both types of
nucleic acid
this type of RNA is used in the ribosome during protein synthesis
rRNA
the process of DNA making copies of itself
replication
the first phase of translation where the mRNA and first tRna join up with a small ribosomal sub unit is
initiation
Dna is found in _____ of eukaryotic cells
nucleus
many ribosomes can be translating a single mRNA strand at the same time this unit is called a
polysome
the enzyme that adds nucleotides to the growing strand during transcription
RNA polymerase
a nitrogenous base with double ring structure
purines
protein associate with DNA to form chromosomes
histones
the enzyme that unzips the DNA strand during replication
helices
a DNA subunit made up of 3 components
nucleotide
the three letter sequence on tRNA that is complimentary to an mRNA codon
anti codon
this type of RNA delivers amino acids to the ribosomes
tRNA
