The light dependent reaction produces B NADPH and ATP which are used in the light independent reaction or dark reaction.
Explanation:
Light dependent reaction also called light reaction occur in the thylakoid of grana. Light dependent reaction leads to the generate ATP and NADPH.
Role of ATP
ATP is an energy rich compound which undergo hydrolysis to generate huge amount of free energy. ATP is formed in the cyclic photo phosphorylation by the transport of electron through various electron carrier leading to generate energy for the phosphorylation of ADP into ATP.
Role of NADPH
NADPH act as reducing agent which is formed as the end product of noncyclic photo phosphorylation.NADPH helps in the reduction of Phosphoglyceric acid(PGA) into Phosphoglyceraldehyde(PGALD). The so formed PGALD undergo further reacts to generate glucose and also to regenerate Ribulose bisphosphate(RUBP).
Answer: Nuclear Fusion occurs when the nuclear components of an atom combine.
Answer:
<h2>A polyadenylation signal or poly(A)
</h2>
Explanation:
Termination. In eukaryotes, transcription is terminated differently for the all 3 different RNA polymerases. Transcription is terminated by two elements: i) a poly(A) signal and ii) a downstream terminator sequence.
In eukaryotic protein-encoding genes, the cleavage site in the RNA occurs between an upstream( the sequence before the cleavage site) AAUAAA and a downstream GU-rich, separated by approx 40-60 nucleotides. After they both have been transcribed, a protein knows as CPSF and another protein called CstF( in humans) helps in termination.
