Why does telomerase have to have a built-in template for dna synthesis?

Biology
1 answer:
Marta_Voda [28]2 years ago
5 0
Telomerase is involved in adding DNA to the end of the lagging strand.

At the ends of linear chromosomes (telomeres), telomerase uses its built-in RNA template to extend the parent DNA template near the end of the lagging strand, providing room for an RNA primer so that lagging strand synthesis can be completed to the end of the chromosome

Which features do most stratovolcanoes and cinder cone volcanoes have in common?
Sergeu [11.5K]

Answer:

Option (2)

Explanation:

Strato-volcanoes are the steep, conical shaped, formed by the alternative beds of ash and lava. The magma in this type of volcano contains high silica content and are comprised of bubbles. When the gases are released from these bubbles, then a greater force is exerted from the bottom towards the surface. Due to this, they are very explosive and ejects a huge amount of materials during eruption. For example, Mount St. Helens .

Cinder cones are the simplest volcanoes with steep sides. They are made of the materials and semi solidified lava that are ejected from the vents of the volcano. Eruptions are often explosive due to the force exerted by the gas and the molten lava and are accumulated near the vent. For example, Paricutin.

<u>These two types of volcanoes are similar in terms of its eruption that is violent and explosive in nature. In addition to that, they both have steep sides. </u>

Hence, the correct answer is option (2).

Chloramphenicol binds in the active site of the large ribosomal subunit and inhibits peptidyl transferase activity in the 23s rr
valentina_108 [34]
This inhibition is restricted to bacterial translation because; the peptidyl transferase is an enzyme aminoacyltransferase as well as the primary enzymatic function of the ribosome, which forms peptide bonds between adjacent amino acids using tRNAs during the process of translation. Therefore, inhibition of this enzyme means that the process oof translation wont take place, hence proteins will not be formed and thus the bacteria will die.
