Mutations
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.
The double stranded DNA molecule unzips
100
In the process of protein synthesis, this molecule serves as an instructions manual.
DNA
100
These are the four nitrogen bases in RNA. Spell them out.
What is Adenine (A), Uracil (U), Cytosine (C), Guanine (G)?
100
What is the definition of a mutation?
A change in the hereditary material of an organism
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.
Free DNA nucleotides bind to the exposed DNA
200
Protein synthesis occurs at this cell organelle.
Ribosome
200
Instead of deoxyribose, RNA nucleotides have this simple sugar.
Ribose
200
How is a chromosome mutation different from a gene mutation?
It affects the structure of part of, or an entire, chromosome
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.
Two DNA strands, which are identical to the first
300
If a DNA sequence is TAC GGC, then this would be the mRNA sequence.
AUG CCG
300
What are two types of RNA?
mRNA, tRNA
300
This type of gene mutation occurs when a base is added or deleted from DNA. It alters the reading of the codons by one base.
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.
the nucleus
400
tRNA matches up with 3-base code on mRNA, resulting in what?
The correct sequence of amino acids
400
This is the term for every 3 bases in a mRNA strand. Each of these codes for one amino acid.
A codon or triplet
400
In meiosis, one or more pairs of chromosomes may fail to separate, resulting in the type of mutation
Chromosome 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 (mitosis)
500
What is created when amino acids are linked together?
A protein
500
A strand of mRNA that is 15 bases long will code for this many amino acids?
five
500
Name the type of gene mutation you see here: ACT TTG CCT CCA ACT ATG CCT CCA
Substitution ---point mutation
