Answer:
Most pre-mRNA molecules have sections that are removed from the molecule, called introns, and sections that are linked or together to make the final mRNA, called exons.
Hey, here it is!!
Can u give me a BRAINLIEST ANSWER???
Extension: Produced by the sartorius and quadriceps femoris group of muscles. Flexion: Produced by the biceps femoris, semitendinosus, and semimembranosus muscles. The popliteus muscle facilitates this movement by unlocking the fully extended knee joint.
Answer:
All cells arise from pre existing cells.
Explanation:
one of the principles on the cell theory states that all cells came from pre existing cells . The two cells are parent cells who are big enough to undergo mitosis. The 4 cells made out of this event are daughter cells .

Answer:
14 CO₂ will be released in the second turn of the cycle
Explanation:
<u>Complete question goes like this</u>, "<em>The CO2 produced in one round of the citric acid cycle does not originate in the acetyl carbons that entered that round. If acetyl-CoA is labeled with 14C at the carbonyl carbon, how many rounds of the cycle are required before 14CO2 is released?</em>"
<u>The answer to this is</u>;
- The labeled Acetyl of Acetyl-CoA becomes the terminal carbon (C4) of succinyl-CoA (which becomes succinate that is a symmetrical four carbon diprotic dicarboxylic acid from alpha-ketoglutarate).
- Succinate converts into fumarate. Fumarate converts into malate, and malate converts into oxaloacetate. Because succinate is symmetrical, the oxaloacetate can have the label at C1 or C4.
- When these condense with acetyl-CoA to begin the second round of the cycle, both of these carbons are discharged as CO2 during the isocitrate dehydrogenase and alpha-ketoglutarate dehydrogenase reactions (formation of alpha-ketoglutarate and succinyl-CoA respectively).
Hence, 14 CO₂ will be released in the second turn of the cycle.
