RNA
RNA contains this sugar
What is ribose?
One strand of DNA serves as a template during this process
What is transcription?
Translation occurs here for both eukaryotic and prokaryotic cells
What is cytosol?
A mutation that involves one nucleotide is called this.
What is a point mutation?
The two major steps to occur during gene expression
What are transcription and translation?
Unlike DNA, RNA contains this base
Uracil
Transcription occurs in the cytosol for these cells
What is prokaryotic?
The translation process makes these
What is a polypeptide?
Information is lost when a chromosome undergoes this type of mutation
What is a deletion?
Gene expression involves these rules
What are complimentary base pairing rules?
This type of RNA brings the information from the nucleus to other parts of the cell
What is mRNA?
RNA polymerase locates promoter, binds, unwinds sequence and synthesizes an RNA strand
What is initiation?
Translation is divided into these three phases
What are initiation, elongation and termination?
This mutation occurs when errors of meiosis and mitosis take place
What is a chromosomal mutation?
The first stage of gene expression
What is transciption?
mRNA is transcribed from this
What is DNA?
Chemical bases during transcription
What is
A-U
C-G
T-A
This is the number of RNA nucleotides that code for an amino acid
What is 3?
Insertions and deletions that change the entire genetic message after the mutation are called these
What are frameshift mutations?
Gene expression acts as both an on/off switch to control when ___ are made
What are proteins?
DNA is double-stranded while RNA is
What is single-stranded?
During transcription this binds to DNA and assembles nucleotides into a strand that is complementary to the DNA template.
What is the RNA polymerase?
The stop codons that reach a ribosome during termination
What are UAG, UAA, and UGA?
UV radiation and cigarette smoke are agents that can cause genetic mutations meaning they can be referred to as this
What is a mutagen?
Genetic information in ___ is transcribed into ___ and then translated into a polypeptide
What are DNA and RNA?
