Two strands of dna produced during replication are copies of each other because each strand in the double helix is
a. identical
b. complementary
c. continuous
d. connected

The correct answer would be B. complementary.

The two strands of the DNA molecule are always complementary to each other.

Complementary means that purine will always make a bond with a pyrimidine.

More specifically, adenine always makes a bond with thymine and guanine always makes a bond with cytosine.

Due to this nature and semi-conservative replication, the two strands of DNA produced during replication are copies of each other.

the abdomen (less formally called the belly, stomach, tummy or midriff) constitutes the part of the body between the thorax (chest) and pelvis, in humans and in other vertebrates. the region occupied by the abdomen is termed the abdominal cavity. the stomach secretes acid and enzymes that digest food. ridges of muscle tissue called rugae line the stomach. the stomach muscles contract periodically, churning food to enhance digestion. the pyloric sphincter is a muscular valve that opens to allow food to pass from the stomach to the small intestine.

the real answer is b. scintillation counter
