What are the consequences of having pyrimidine dimers in dna? 1. they form an extra phosphodiester bond between them. 2. they create an apyrimidinic site 3. these dimers distort the dna structure and result in errors during dna replication. 4. they prevent the transcription of the dna into rna.

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.
