In what process is mRNA synthesized?
Transcription
Translation
DNA Replication
Mitosis
Where does TRANSCRIPTION occur?
Nucleus
Ribosome
Cytoplasm
Mitochondria
Why must transcription occur where DNA can be found?
because DNA can't leave
because ribosomes are in the nucleus
because DNA polymerase is found there
because helicase unzips the DNA
How many codons equals 1 amino acid?
1
2
3
4
Choose the sequence of the mRNA strand that would be match up with to the following strand:
GTAGTCA
UATUAGA
ACGACTG
CAUCAGU
CATCAGT
DNA holds the code for making
lipids
carbohydrates
proteins
sugars
What is the correct amino acid sequence for the mRNA code AUG GCA AAC CGU
Met-Ala-Asn-Ala
Met-Ala (because the third codon codes for STOP)
Ileu-Ala-Asn-Ala
Met-Ala-Asn-Arg
Ileu-Ala-Asn-Ala
What amino acid would be added to the protein being formed during translation if the mRNA codon reads "AUG?"
Phenylalanine
Tyrosine
Leucine
Methionine
Mutations can be negative because
They can cause cancer
They can cause ninja turtles
They can help an organism thrive in its environment.
They can affect offspring.
Mutations can benefit humans because they can:
Cause illness
Make an organism more suited to live in its environment.
Make organisms live shorter lives
Cause organisms to grow extra limbs.
A mutation is defined as:
A change in the cell's structure
Anything that changes in an embryo
Any change in the physical features of a human
A change in the DNA sequence
T-G-A-C-C-A
T-G-A-G-C-A
