Franklin’s picture of DNA demonstrated that
What is DNA is a helix made of two strands of nucleotides.
100
Watson and Crick
What is The scientist(s) credited with establishing the structure of DNA is/are
100
Nucleotides
What is Molecules of DNA are composed of long chains of
100
Gene
What is A segment of DNA that contains the code for making one specific protein is called a(n)
100
Protiens
What is DNA in the nucleus controls activities in the rest of the cell by coding for the production of
200
The amount of guanine in an organism approximately equals the amount of
What is Cytosine
200
During DNA replication, a complementary strand of DNA is made for each original DNA strand. Thus, if a portion of the original strand is CCTAGCT, then the new strand will be
What is GGATCGA
200
The original strand of DNA is ATGGCA. This strand undergoes a frameshift mutation and appears as follows
What is ATGGCCA
200
The purpose of many replication forks (bubbles) in eukaryotes is to
What is speed up replication
200
In RNA molecules, adenine is complementary to
What is uracil
300
During trascription
What is mRNA is produced
300
Each nucleotide triplet in mRNA that specifies a particular amino acid is called a(n
What is Codon
300
The process of making proteins using the information contained in a molecule of messenger RNA (mRNA) is called
What is translation
300
The function of transfer RNA (tRNA) molecules is to
What is transport (carry) amino acids to a codon on mRNA
300
Why is the mRNA in the cytoplasm (at the ribosome) smaller than the mRNA in the nucleus
What is Segments of the RNA called introns are removed in the nucleus
400
A gene mutation can be thought of as a
What is change or an error in a nucleotide sequence.
400
Scientists have determined that the genetic codes for amino acids to make proteins are
What is universal (the same for all organisms).
400
In the human body, red blood cells and liver cells differ in the functions they perform. Red blood cells are responsible for transporting oxygen to all parts of the body and liver cells work in the process of detoxification. Why do these eukaryotic cells differ in their functions
What is Red blood cells and liver cells have the same DNA but different genes are expressed
400
How many chromosomes does a human somatic (body) cell contain
What is 46
400
An animal that has foreign DNA in their cells is called
What is transgenic
500
The process of separating DNA molecules by size and shape is called
What is electrophoresis
500
The acronym GMO stands for
What is Genetically Modified Organisms
500
Some genetic diseases can be treated with medication and/or lifestyle changes. But the only way to cure genetic diseases is to
What is remove and replace the affected gene
500
Which of the following would be possible as a result of the Human Genome Project
What is Identifying the potential risk for developing breast cancer
500
The cloning of Dolly the sheep in 1997 was a result of the fusion of
What is an empty egg cell and the DNA from an adult mammary cell
