Answer: Exons
Explanation:
In eukaryotic cell the primary transcript are very long the contains coding region (exons) and non coding region (introns)
The parts of the gene sequence that are expressed (coding region) in the protein are called exons, because they are expressed, while the parts of the gene sequence that are not expressed in the protein are called introns, because they come in between the exons.
Intron is a portion of a gene that does not code for amino acids. These Intron sequence are cleaved out and exons are spliced (I. E combine together) to form the mature mRNA molecule.
Exons are the mRNA parts that are kept and used to make protein.
A would be the best answer out of these choices because it’s closest to hot during the day and cool at night
Cardiac muscles as they have striations and are branching cells.
Cardiovascular system - contains all of our muscles necessary , skeletal system- contains the bones to create the shape of the body and respiratory system which allows us to breathe
The organism cannot move and is made up of many cells. This means it is some sort of plant. Since it produces spores and is unable photosynthesize, it means it is a fungus that belongs to the Fungi Kingdom.
