The correct answer is: introns
Processing of mRNA is process that occurs only in eukaryotic cells. After the transcription, newly formed mRNA molecule is called and it must be processed into a messenger RNA (mRNA). Processing includes:
• Addition of a 5' cap to the beginning of the RNA
• Polyadenilation- addition of a poly-A tail (tail of A nucleotides) to the end of the RNA
• Splicing- removal of introns and linking the exons
After these steps mRNA is mature and used for the further steps (e.g. translation).
Sometimes some genes are alternatively spliced.
Answer:
subliminal perception.
Explanation:
Subliminal perceptions, also known as subliminal messages, are messages, either visual or auditory, that are presented just beyond the threshold of human perception. A subliminal perception may not be audible enough that the conscious mind might register it but be audible enough for the subconscious mind.
For example it might be an image transmitted briefly and unperceived consciously and yet perceived unconsciously.
Answer:
''Planets moves around the sun with constantly changing speed.''
''The sun uses its gravity to pull the planets towards it''
Explanation:
These two statements describes Newtons laws of Motion and Gravity. With statement 1, which shows the motion of the planets constantly changing due to the attraction of the sun. When the planets come close together to the sun, its orbital speed increases while on the other hand, when the planets goes farther from the sun, its orbital speed decreases. The statement 2 indicates that sun attracts other planets due to its gravity which allow them to move in a curved.
