100
These are the four nitrogen bases in DNA.
What is Adenine (A), Thymine (T), Cytosine (C), and Guanine (G)?
100
This is the first step in DNA replication.
What is the double stranded DNA molecule unzips?
100
In the process of protein production, this molecule serves as an instructions manual.
What is DNA?
100
These are the four nitrogen bases in RNA.
What is Adenine (A), Uracil (U), Cytosine (C), Guanine (G)?
100
This is the term for any agent that causes a change in DNA. Examples include chemicals, radiation, and extreme temperatures.
What is a mutagen?
200
This is the shape of a DNA molecule. It is also often described as a twisted ladder.
What is the double helix?
200
This happens after the DNA molecule has unzipped.
What is free DNA nucleotides bind to the exposed DNA?
200
If a DNA sequence is TAC GGC, then this would be the mRNA sequence.
What is AUG CCG?
200
Instead of deoxyribose, RNA nucleotides have this simple sugar.
What is Ribose?
200
This type of mutation may or may not affect the amino acid sequence of a protein.
What is a point mutation?
300
If one strand of DNA is CATGGA, then the complementary strand is this.
What is GTACCT?
300
This is the end product of DNA replication.
What is two DNA strands, which are identical to the first?
300
In this process, the DNA sequence of a gene is transcribed into a single stranded mRNA molecule.
What is transcription?
300
These are the three types of RNA.
What is mRNA, rRNA, tRNA?
300
This type of mutation occurs when a base is added or deleted from DNA. It alters the reading of the codons by one base.
What is a frameshift mutation?
400
DNA is a polymer made up of repeating units, or building blocks, called this.
What is nucleotides?
400
DNA replication occurs in this part of the cell.
What is the nucleus?
400
In this process, a single-stranded mRNA is translated into a sequence of amino acids.
What is translation?
400
This is the term for every 3 bases in a mRNA strand. Each of these codes for one amino acid.
What is a codon?
400
Original DNA: TAC TTG GCA GGG Mutated DNA: TAC TTT GCA GGG The above is an example of this type of mutation?
What is a point mutation?
500
These are the three components of a DNA nucleotide.
What is 1. sugar (deoxyribose) 2. phospate 3. nitrogen base
500
DNA replication is important because it allows this cell process to take place. (hint: think about growth)
What is cell division?
500
Protein production occurs at this cell organelle.
What is the ribosome?
500
A strand of mRNA that is 15 bases long will code for this many amino acids?
What is 5?
500
This type of mutation might cause a gene to code for 9 amino acids instead of 10.
What is a frameshift mutation?
