Answer:
a. discontinuous
b. lagging
c. phosphodiester bonds
d. DNA polymerase I
e. RNA primase
Explanation:
Okazaki fragments are so called because these are synthesized in a discontinuous unlike in the leading strand where the new DNA strand is synthesized continuously. This is due to the fact that the lagging strands runs in the 5' to 3' direction, thus, a means has to be devised such that new DNA can be synthesized in the 5' to 3' direction. DNA ligase aids in ligating these fragments together. DNA polymerase can not begin the synthesis of the new DNA strand thus, the RNA primers helps to perform this function.
<em>Cartilaginous joints</em> is not a functional classification for joints.
Answer: Option 2
Explanation:
The joints are classified based upon their <em>structure and function</em>. Based upon the composition as well as presence or absence of the cavity, the joints are <em>structurally</em> classified as:
- Fibrous joints
- Cartilaginous joints
- Synovial joints
On the other hand, based upon the functions performed by the joints, the <em>functional </em>classification of joints are as follows:
- Diarthrosis
- Amphiarthrosis
- Synarthrosis
Thus it is inferred that, cartilaginous joint is structural classification of joints, not functional.
They both breathe air, and some insects are the birds prey.
