Transcription and translation of DNA

Transportation and translation of DNA

MHS Douglas 2021

Multiple Choice

DNA is found in the chromosomes in the

• nucleous

• mitocondria

• vacuole

• Golgi bodies

Multiple Select

When DNA is copied by mRDA the nucleotide pairs are matched up so that (DNA to RNA)

• guanine pairs with cytocine

• adenine pairs with thymine

• thymine pairs with adenine

• adenine pairs with uracil

• cytosine pairs with guanine

Multiple Choice

polymerase is a protein known as an

• enzyme

• amino acid

• glucose

• carbohydrate

Multiple Choice

mRNA is built in the

• nucleolus

• cytoplasm

• ribosomes

Poll

there are ___ amino acids that might be coded for by the codon

• 2

• 3

• 20

• 30

Multiple Choice

we have deciphered the codon so we know which ________ _____ will be chosen for each 3 letter sequence

• nucleic acid

• sugar molecule

• amino acid

• protein enzyme

To read this chart you start with the first letter in the codon, then follow

that to the next outside circle then the last letter. For example G G G would pull glycine,

So would GGA GGC and GGU

Multiple Choice

all codons code for unique amino acids. no two codes can call for the same amino acid

• true

• false

Multiple Choice

translation involves tRNA in the

• nucleus

• cytoplasm

• ribosome

• cell wall

The transcription occurs in the nucleus. mRNA moves out and goes to

Multiple Select

tRNA is built from the

• mRNA

• DNA

Poll

there are special codon for

• where to stop the peptide chain

• where to start the peptide chain

• each type of amino acid

Multiple Choice

translation is the first step of building a protein

• false

• true

Open Ended

If there is a mutation in the gene sequence then the mRNA will tell the tRNA to choose _______________________?
