Which of the following would be most useful in studying human genetic diseases?
the nucleotide sequences of species with similar genetic diseases
the diets of species with similar genetic diseases
the embryonic stages of species with similar genetic diseases
the production of gametes in species with similar genetic diseases
A mutation resulting in the change of one amino acid
substitution-missense
substitution-silent
frameshift-insertion
frameshift-deletion
A mutation resulting in no change from the original amino acid sequence
substitution-silent
substitution-nonsense
substitution-missense
frameshift
A mutation that results in a premature stop codon
substitution-nonsense
substitution-silent
substitution-missense
frameshift-insertion
A mutation that results in the change of several amino acids after the point of mutation
frameshift
nonsense
silent
missense
What is the purpose of translation?
to replicate DNA before cell division
to assemble mRNA into a chain
to synthesize amino acids that open up the DNA
to use the genetic code to form a specific sequence of amino acids
If I give you a DNA template strand and ask you to give me the amino acid sequence, what will you do?
use the DNA with the codon chart and just replace the T with U
transcribe the DNA into mRNA first and then use the mRNA with the codon chart
When does synthesis of DNA happen?
S phase
G1 phase
M phase
G2 phase
What are the two overall processes in the cell cycle?
interphase and mitosis
prophase and interphase
mitosis and meiosis
mitosis and prophase
During mitosis, when do spindle fibers separate the chromosomes?
anaphase
metaphase
telophase
prophase
All of your genes aren't being transcribed and translated all the time. There are triggers that signal for certain genes to be transcribed/translated so certain proteins are produced when needed. (seasonally-colored animals are an example of this - like those bunnies where their fur color changes to white in the winter)
I understand
I didn't actually read that, I need to go back and read it (don't pick this one)
Why are your stomach cells different from your muscle cells?
they have different DNA, so they make different proteins
they evolved differently and cannot make the same proteins
they have different kinds of ribosomes
they transcribe/translate different combinations of genes from the same DNA
Except for eggs/sperm, do all of the cells in your body have the same DNA/genes?
yes, but each type of cell is triggered to only produce certain proteins from the DNA
no, each type of cell has unique DNA that codes for unique proteins
In which type of cell could a mutation affect the offspring of the organism?
egg/sperm
liver cell
nerve cell
lung cell
How are differences in traits determined?
the sequence of DNA nucleotides
the location of sugar groups in DNA
the number of bases in DNA
the phosphate groups in DNA
What is the most important part of DNA? The part that will affect what traits are expressed in the organism?
sequence of nucleotides
number of hydrogen bonds
sequence of phosphates
number of carbons
Which enzyme is involved in transcription
RNA Polymerase
DNA Polymerase
Helicase
Ligase
Which of the following processes occurs in the nucleus
DNA Replication and Transcription
DNA Replication and Translation
Transcription and Translation
Translation and Modification
What are the subunits of DNA
nucleotide
bases
hydrogen bonds
sugars
Transcribe: ATC
UAG
AUC
TAG
UUG
CAU = Histidine
AAA = Asparagine
AUG = Isoleucine
UGG = (stop)
