AP Bio Transcription and Translation

Transcription

• makes RNA using a DNA template
• make protein using an RNA template
• makes RNA using a protein template
• makes DNA using an RNA template

RNA polymerase is the enzyme that functions in

• translation
• DNA replication
• transcription
• DNA repair

The template strand of DNA will be ______________ to the RNA  transcribed

• identical
• identical except T is replaced with U in RNA
• identical except U is replaced with T in RNA
• complementary

If the coding strand of DNA has the following sequence:
AGTCAGA
what would be the sequence of the transcribed RNA?

• AGUCAGA
• UCAGUCU
• ACUGACA
• UGTCUGU

Which form of RNA carries the code for producing Protein?

• rRNA
• mRNA
• tRNA
• iRNA

Ribosomes

• have an anticodon and amino acid end
• serve as the site of transcription and are composed of rRNA and protein
• serve as the site of translation and are composed of rRNA and protein
• are located in the nucleus of the cell where translation takes place

A piece of template DNA has the sequence AGA.  What would be the sequence of the anticodon on the tRNA?

• UCU
• AGA
• TCT
• UGU

There are ____codons that code for amino acids and the other 3 code for ___________.

• 20......stop codons
• 61.....stop codons
• 20....start codons
• 61....start codons

The mRNA strand being transcribed will be made in the 

• 5' to 3' direction
• 3' to 5' direction
• 5' to 3' on the leading strand and 3' to 5' on the lagging strand
• amino to carboxyl direction

mRNA will likely be________compared to the template gene in the DNA

• longer because exons are added to the mRNA
• shorter because introns are removed from the mature mRNA
• longer because introns are added to the mRNA
• shorter because exons are removed from the mature mRNA
