Text SolutionText solutionverified iconVerified

Segmentation: is the serial repetition of similar body parts along with the length of an animal. The body of animals can be truely segmented or pseudo/false segmented. 
True segmentation is found in annelids, arthropods and some chordates. In this, there is a linear repetition of body parts and each repeated unit is called somite (metamere). 
In earthworms, the successive somites are essentially similar but they are dissimilar in different body regions of a crayfish or insect. Metamerism is conspicuous both externally and internally in annelids. 
Pseudosegmentation is seen when body is divided into number of pseudosegments which are independent of each other. Each segment is able to perform all the vital function of body. Body grows by the addition of new segments from the anterior end, e.g., tapeworm.

Fill in the blanks and then reorder sentences to construct a complete paragraph on the sequence of events that occur with blood glucose following a meal. After a meal, blood glucose levels increase. The high blood level of glucose stimulates the pancreas to secrete insulin. Insulin promotes glucose transport from the blood into the cells. Blood glucose will decrease back to normal levels in the absorptive state. The liver plays a role in this process. Glucagon is also involved in regulating blood glucose levels.

PROBLEMS Which statements are true? Explain why or why not 51 The majority of cells in your body have exactly the same nucleotide sequence in their genomes. 52 In a replication bubble, the same parent DNA strand serves as the template strand for leading-strand synthesis at one replication fork and as the template for lagging-strand synthesis at the other fork. 53 In E. coli, where the replication fork travels at 500 nucleotide pairs per second. the DNA ahead of the fork-in the absence of topoisomerase-would have to rotate at nearly 3000 revolutions per minute. 5-4 When bidirectional replication forks from adjacent origins meet, a leading strand always runs into a lagging strand. 55 DNA repair mechanisms all depend on the cell having two homologous chromosomes.

Kaili is setting up a PCR reaction. She knows that a very important enzyme is used for PCR. The enzyme is called Taq polymerase. It is called that because the Taq stands for Thermus aquaticus, which is the bacterium that was discovered in hot springs many years ago. Kaili knows that the enzyme is a protein. She therefore knows that the protein came from an RNA sequence, which was originally encoded by a DNA sequence. Three of the following DNA sequences are most likely to encode the RNA that encodes the Taq enzyme. What are they? Choose all that apply and only those that apply.

  2. 5CAGTGGCAGTGACCT-3
