Bio 123 Chapter 10 Quiz: DNA
If you had a DNA sequence that is 5' GATTACA 3', what would be the corresponding RNA sequence?
3' CUAAUGU 5'
In any strand of DNA
50% of the nucleotides will be purines and 50% of the nucleotides will be pyrimidines.
Which scientist is generally credited for taking the best X-crystallography photograph of DNA that was used to determine the structure of DNA?
Rosalind Franklin
DNA replication is best described as
Semi-conservative, each daughter strand contains 50% of the original strand.
Which molecule is responsible for bringing amino acids to a ribosome?
tRNA
Gene duplications were important for the evolution of
Color vision in primates, including humans
Which of the following statements regarding DNA and RNA are correct?
DNA and RNA nucleotides are comprised of three components, including a 5-carbon sugar, nucleotides are linked together by Phosphodiester bonds forming a sugar-phosphate backbone.
The flow of information in a cell is best described as
DNA is transcribed to mRNA, the information in mRNA is then translated into a sequence of amino acids in a ribosome.
During DNA synthesis
DNA polymerase adds nucleotides to the 3' end of the growing daughter strand.
The two strands of DNA are held together by
Hydrogen bonds between a purine and a pyrimidine.
In a eukaryotic cell that is going to make a protein used to regulate glycolysis, translation will take place
In a free floating ribosome in the cytoplasm.
The genetic code is best described as
All of these are correct
Mutations can be induced by
All of these choices
Mutations are an alteration in the sequence of which polymer?
Deoxyribonucleic Acid
Viruses that enter our cells
Enters a lytic lifecycle if they begin to immediately form new viruses
In any nucleotide, the nitrogenous base
Is attached by a polar covalent bond to the 1' carbon of the sugar.
During DNA replication, the lagging strand
Is replicated in fragments that are antiparallel to the parent strand. The fragments are called Okazaki fragments.
The paradox of genetic disorders
Is that genes are often thought of as the disorder they cause, but genes don't exists to cause disorders.
A retrovirus
Reverse transcribes DNA from an RNA template
