What is a mutation?
a change/mistake in DNA which is always harmful to an organism
a change/mistake in DNA which could be beneficial or harmful to an organism
a copy of the original DNA
mutation is part of natural selection
ATC - AGT - GAT
Is a codon is a sequence of three nucleotides that code for an amino acids. If the DNA sequence shown here goes through transcription and translation, how many amino acids will result from this sequence.
3
9
1
infinite
A cell is replicating it's DNA. Part of the DNA strand reads: ACC - TAC - GGA. The new strand built off this section will read: TGG - ATG - CCT. What effect might this have when DNA replicates in the future.
The cell with the new DNA will receive "new directions" since its a different strand
Only the mutated part of the DNA will be used by the cell
The new strand is complementary so it codes for the "same directions"
The new strand codes for mRNA
Original DNA: GAG CTC GAC
Mutated DNA: GAG CTC CAC
This is an example of which type of gene mutation?

The process of making proteins: DNA provides the template to create mRNA this process is called ____ then mRNA goes to the ribosome where it awaits tRNA to create a polypeptide chain this process is called ___
transcription; translation
translation; transcription
replication; transcription
replication; translation
Select the correct option that completes transcription: ATC - GCT - CGA
UAG - CGA - GCU
TAG - CGA - GCT
ATC - GCT - CGA
mRNA to tRNA to protein
If the mRNA strand contains: AUG - UAC. Select the complementary anticodon.
UAC - AUG
TAC - ATG
AUG - UAC
tRNA
Laura is studying with her friend for the Bio EOC. Laura states "DNA polymerase is the enzyme that helps build a complementary RNA strand during transcription". Select the correct response her friend should say:
DNA polymerase is an enzyme but its used for building a complementary DNA strand during DNA replication
DNA polymerase is not an enzyme, but it is used to build an identical DNA strand during RNA replication
Her friend agrees that Laura's statement is correct
Yes, it's used during transcription, but DNA polymerase is not an enzyme its a carbohydrate
Which process occurs in the nucleus of the cell
DNA replication and transcription
Transcription and translation
Transcription only
DNA replication, transcription, translation
The process of replication is being shown in the image. Which option below best describes what happens during replication?
DNA is unzipped and proteins are made from amino acids
DNA is unzipped and one strand is used to make the complementary strand of DNA
DNA is unzipped and mRNA is made from a double strand of DNA
DNA is unzipped and tRNA is made from a double strand of DNA
A meteor that crashes into Earth is tested for microbes. Turns out there are prokaryotes on the meteor. After running tests scientists discover that the prokaryotes contain the same DNA composition as found on earth. Select the correct options that reflects the DNA found on earth.
Adenine, Thymine, Cytosine, Guanine
deoxyribose sugar, phosphate group, nitrogen bases like: adenine, thymine, cytosine, guanine
ribose sugar, phosphate group, nitrogen bases like: adenine, uracil, cytosine, guanine
Adenine, Uracil, Thymine, Cytosine, Guanine
