Genetics and Molecular Biology Flashcards

Front

Anticodon

Back

A 3 nucleotide sequence on a tRNA molecule that are complementary to a corresponding codon on mRNA.

Front

Bacteriophage

Back

A virus that infects bacteria cells.

Front

Base pairing rules

Back

Adenine pairs with thymine and guanine pairs with cytosine (A=T, C=G).

Front

Central Dogma

Back

Genetic information flows in one direction: DNA, to RNA, to Protein.

Front

Codon

Back

A 3 nucleotide sequence on mRNA or DNA which together form a genetic code.

Front

DNA Polymerase

Back

An enzyme that adds complementary DNA nucleotides to a strand of DNA during replication.

Front

Double helix

Back

Physical structure of DNA that has two parallel strands intertwined around a common axis.

Front

Exon

Back

A sequence of DNA or RNA that DOES code for a protein.

Front

Frameshift mutation

Back

A genetic mutation that occurs due to an insertion or deletion of genetic information which causes the reading frame to change.

Front

Intron

Back

A sequence of DNA or RNA that DOES NOT code for a protein.
