MCAT DNA Replication
MCAT DNA
Question | Answer |
---|---|
mRNA | synthesizes protein |
rRNA | structural component of ribosomes |
tRNA | carries the an amino acid from the cytoplasm to the ribosomes for incorperation to a growing protein |
proof-reading is called | 3'-5' exonuclease activity |
toposiomerases | fixes suppercoiling |
RNA pol I | makes rRNA |
proteins are made... | in the cytoplasm |
RNA pol II | makes mRNA |
three differences bw DNA and RNA | DNA uses deoxyribose instead of ribose; DNA uses thymine instead of uracil; DNA is double stranded while RNA is usually single |
RNA pol III | makes tRNA |
transformation | the genetic alteration of a cell resulting from the uptake, genomic incorporation, and expression of foreign genetic material inheritable genetic combo |
conjunction | the transfer of genetic material between bacteria through direct cell-to-cell contact. Donor male (+); recipient female (-). They have sex pili |
transduction | is the process by which DNA is transferred from one bacterium to another by a virus. |
