Ch 14.1-2 Lecture

Both are made of nucleotides

DNA is double stranded and RNA is single stranded

DNA and RNA contain a different type of sugar

They both consist of the same four bases

All of these choices are true

mRNA

rRNA

tRNA

zRNA

Because DNA can not leave the nucleus

To maintain a balance of electrolytes

Because the cytoplasm needs to move in and out of the the nucleus

Because amino acids need to get moved to the ribosomes

DNA polymerase

RNA polymerase

DNA hydrolase

RNA hydrolase

ATG GCC AGT TTG TAG

TAC CGG TCA AAC ATC

UTG GCC UGT TTG TUG

True

False

They are made up of long chains of amino acids

They are the main component of muscle tissue

Enzymes are a type of protein

They are just long straight strands of polypeptides
