100
The full name for DNA.
What is DeoxyriboNucleic Acid?
100
The process which comes first in gene expression and turns DNA into mRNA.
What is transcription?
100
The phase of the cell cycle in which DNA is replicated.
What is S-phase? (synthesis)
100
The base pairings present in DNA.
What is A-T and C-G?
100
The waste product of photosynthesis.
What is oxygen?
200
The shape of a DNA molecule.
What is a double helix?
200
The organelle which conducts translation.
What is a ribosome?
200
The type of macromolecule that "unzips" and rebuilds the DNA.
What is a protein (enzyme)?
200
The result of transcribing ATG GCA ACC.
What is UAC CGU UGG?
200
The phase in which a cell spends 90% of its life cycle.
What is interphase?
300
The components of DNA's backbone.
What are phosphate and sugar (deoxyribose)?
300
The macromolecule that links gene expression and traits.
What is a protein?
300
DNA replication is said to have this trait because half of the old DNA is used to serve as a template for the formation of new strands.
What is semiconservative?
300
The codon on mRNA binds to this section of tRNA in translation.
What is an anticodon?
300
The organelle which separates the cell from its environment and maintains homeostasis.
What is the cell membrane?
400
The bonds which hold the two strands of DNA together.
What is a hydrogen bond?
400
The process being shown in this image.
What is gene expression?
400
The purpose for conducting DNA replication is to maintain the proper number of these.
What are chromosomes?
400
The amino acid sequence translated by the sequence
AUG CGC UAU.
What is Met-Arg-Tyr?
400
This can occur during mitosis and meiosis, resulting in an unequal number of chromosomes.
What is nondisjunction?
500
DNA and RNA share some similarities, but one of their most notable differences is in the nucleotides present. In RNA which thymine is replaced with this base.
What is uracil?
500
In phenylketonuria (PKU), an enzyme that converts one amino acid into another does not work properly. PKU characterizes this type of mutation.
What is a substitution mutation?
500
The name of the enzyme which performs DNA replication, adding new nucleotides to the newly formed strands.
What is DNA polymerase?
500
This type of mutation was caused by changing the DNA sequence in a gene from sequence 1 to sequence 2.
You must show the RNA sequence and amino acid sequence to answer.
1) ATG GAA GCA CGT
2) ATG TAA GCA CGT
What is a nonsense mutation?
500
The correct order for the following events
A. Attachment of double stranded chromosomes to the spindle apparatus
B. Formation of single-stranded chromosomes, which are moved to opposite ends of the cell
C. Disintegration of the nuclear membrane
D. Nuclear membrane formation around each set of chromosomes, forming two nuclei
E. Synthesis of a spindle apparatus
What is C -> E -> A -> B -> D?
