MOLECULAR GENETICS

Question 1

DNA occurs most often as __________, a spiral staircase-spiral shaped molecule composed of two nucleotide chains hydrogen-bonded to each other

Answer 1

double helix

Question 2

is the base principle of DNA replication and transcription as it is a property shared between two DNA or RNA sequences, such that when they are aligned antiparallel to each other, the nucleotide bases at each position in the sequences will be complementary, much like looking in the mirror and seeing the reverse of things.

Answer 2

complementarity

Question 3

after one round of replication, the original pair is not conserved. each strand becomes a part of a new duplex

Answer 3

semiconservative replication
