DNA vs. RNA
Transcription
Translation
The Genetic Code
Mutations
100
RNA contains this many strands.
What is 1?
100
Transcription takes place in this area of the cell.
What is the nucleus?
100
Translation takes place at this cell organelle found in the cytoplasm.
What is a ribosome?
100
If the DNA sequence reads ATC, the mRNA would read this.
What is UAG?
100
The base "A" is accidentally added in place of a "T" during DNA replication. This type of mutation has occurred.
What is a substitution?
200
RNA contains this base, not found in DNA.
What is uracil?
200
DNA is used to make this molecule.
What is mRNA?
200
An mRNA molecule is used to build this molecule.
What is a protein?
200
If a codon on the mRNA reads UGA, the anticodon on the tRNA would read this.
What is ACU?
200
This type of mutation involves adding or deleting a base in a DNA sequence.
What is a frameshift mutation?
300
DNA contains the sugar deoxyribose. RNA contains this sugar.
What is ribose?
300
This is the reason DNA cannot leave the nucleus.
What is its large size? (Or it needs to be protected)?
300
The three bases on an mRNA, called this, determines the order of the amino acids.
What is a codon?
300
This amino acid is coded by the mRNA codon, UCG.
What is Serine?
300
Ultraviolet radiation can cause genetic changes. UV radiation is considered to be this.
What is a mutagen?
400
There are this many types of RNA.
What is 3?
400
This enzyme helps direct the process of transcription by adding the correct RNA nucleotides to the template DNA strand.
What is RNA polymerase?
400
The tRNA molecule carries an amino acid opposite three unpaired bases called this.
What is an anticodon?
400
If the DNA sequence is TACCCGTAA, these are the corresponding amino acids, in order.
What are Methionine, Glycine, Isoleucine?
400
Chromosome 21 contains extra genes. This type of mutation occurred.
What is duplication?
500
This type of RNA is involved indirectly in protein synthesis. It makes up part of the structure of ribosome.
What is ribosomal RNA (rRNA)?
500
This sequence of bases determines where transcription will start on the DNA molecule.
What is a promoter?
500
This type of codon ends translation.
What is a stop codon?
500
These are the codons that correspond to the amino acid, Glutamic acid.
What are GAG and GAA?
500
This is the reason why frameshift mutations are more harmful than point mutations.
What is that they cause every amino acid after the mutation to change, not just one amino acid?
