RNA
RNA contains this sugar
What is ribose?
One strand of DNA serves as a template during this process
What is transcription?
This is the number of nucleotides that code for an amino acid
What is three?
A mutation that involves one or a few nucleotides is called this.
What is a point mutation?
In E. coli, the lac operon controls the breakdown of this
What is lactose?
Unlike DNA, RNA contains this base
Uracil
During transcription this binds to DNA and assembles nucleotides into a strand that is complementary to the DNA template.
What is RNA polymerase?
The tRNA bases called this are complementary to 3 consecutive nucleotides on an mRNA molecule
What is an anticodon?
Information is lost when a chromosome undergoes this type of mutation
What is a deletion?
These are involved in prokaryotic gene expression but not eukaryotic gene expression
What are operons?
This type of RNA brings the information from the nucleus to other parts of the cell
What is mRNA?
Eukaryotic DNA consists of regulatory sequence,the gene that is being transcribed and this
What is a promoter?
The codon that signals the end of a growing polypeptide is called this.
What is the stop codon?
Inversion is an example of this type of mutation
What is a chromosomal mutation?
This regulates the expression of most eukaryotic genes.
What are transcription factors?
mRNA is transcribed from this
What is DNA?
These are excised or removed from eukaryotic mRNA prior to it leaving the nucleus
What is an intron?
The order of nitrogenous bases in DNA determines the order of these in proteins.
What are amino acids?
Insertions and deletions that change the entire genetic message after the mutation are called these
What are frameshift mutations?
What are specialize or differentiate?
These are the 3 differences between DNA and RNA
What is ribose, uracil and single-stranded?
In eukaryotes, transcription occurs here
What is the ribosome?
Each amino acid can be coded for by how many codons?
The element bromine can cause a genetic change so bromine is this
What is a mutagen?
A mutation in a series of genes called these can change the organs that develop in specific parts of an embryo.
What are Hox genes?
