3 sites in a ribosome:
The charged tRNA first enters the ribosomal A site...then moves to the P site and finally to the E site.
Because they only ask for 2 I would say A then P.
Haploid is 1/2....and diploid is doubled....so I say 40
In DNA Nucletide monomer are linked to the next through covalent bonds
Hope this helps!
The correct answer is: oxaloacetate
Anaplerotic reactions are chemical reactions that form intermediates that can be used in the further steps of metabolic pathways. These reactions are very important, because it is crucial for the cell to regulate concentrations of TCA cycle metabolites and intermediates.
The reaction in which pyruvate is converted to oxaloacetate is catalyzed by pyruvate carboxylase and it occurs in mitochondria. Also, pyruvate can be converted to L-malate, in a similar way.
Sperm cells inside the pollen grain travel down the pollen tube and into the ovary which contains the ovules. Fertilization occurs when one of the sperm cells fuses with the egg inside of an ovule
