Answer:
D) splicing together of introns through rna processing
Explanation:
Transcription is the process by which an mRNA molecule is synthesized using a DNA template. However, the initial mRNA transcript is considered pre-mRNA until it undergoes post-transcriptional processing to become matured. The mRNA processing involves three steps viz: capping of 5', polyadenylation and splicing.
The 5' end of the mRNA molecule is capped with a 5' cap in the first mRNA processing stage. This is followed by the addition of a poly(A) tail to the 3' end of the mRNA strand. The last step called Splicing involves removal of introns (non-coding regions of sequence) from the mRNA sequence while the remaining protein-coding regions called EXONS are joined or spliced together.
Hence, option D which says: splicing together of introns through rna processing is not correct because exons are spliced together during splicing step of mRNA processing.
Answer:
The respiratory cycle converts NADH and FADH2 into reactants that the Krebs cycle requires to function. Thus, if oxygen is not present, the respiratory cycle cannot function, which shuts down the Krebs cycle. For this reason, the Krebs cycle is considered an aerobic pathway for energy production.
Explanation:
The Earth's orbit around the sun would be the correct answer to that. :) Good Luck
Answer:
Semi-Conservative
Explanation:
After DNA replication, the parental DNA molecule contains two original DNA strands while the daughter molecule is composed of two newly synthesized strands. In this model, the two DNA strands in the parental molecule separate from each other and serve as templates for the synthesis of daughter strands.
