NGSS.HS-LS1-1

Where does the process labeled as 12. occur?

• nucleus

• cytoplasm

• mitochondrion

• chloroplast

What is the importance of tRNA to the process of protein synthesis?

• reads the genetic code in mRNA to assemble proteins

• copies the genetic code in DNA to the ribosome

• carries amino acids to the ribosome

• helps the ribosome to release the synthesized protein

Why must transcription occur where DNA can be found?

• DNA can't pass through the nuclear membrane

• ribosomes are found in the same location as the DNA

• RNA polymerase is able to ensure DNA replication at that location

• tRNA can only access the genetic information in DNA in certain circumstances

Which of the following is a codon?

• ACT

• ATG

• AUG

• AUT

How many nucleotides are needed to code for one amino acid?

• 1

• 2

• 3

• 4

TRANSLATE this RNA sequence: AUGCAAUGA

• Met-Glu-Stop

• Met-His-Stop

• Thr-Glu-Stop

• Thr-Pro-Stop

Which of the following units are repeatedly joined together to form a strand of DNA?

• amino acids

• nucleotides

• fatty acids

• monosaccharides

DNA molecule segment is : TTACGCAAG
The mutated DNA segment is TTACGCAAC. This is an example of a ___ mutation.

• Substitution

• Insertion

• Deletion

• Frameshift

If an original DNA strand is ATT TGA GCC, and a point mutation that is not a frameshift mutation occurs, the mutated DNA strand might look like...

• ATT GAG CC

• ATT TGA CGC C

• ATT TCA GCC

• All of the these are possiblities
