Answer:
The mRNA for an Alzheimer-related gene is 2400 nucleotides long when isolated from neurons, but 2900 nucleotides long when isolated from glial cells. Genomic DNA isolated from the two cell types show the identical nucleotide sequence. the mechanisms that best accounts for the difference in the sizes of the mRNAs is the alternative slicing mechanism.
Explanation:
A controlled process during gene expression that results in a single gene coding for multiple proteins is referred to as alternative splicing.
During this process, particular exons of a gene may be included within or excluded from the final, processed messenger RNA (mRNA) produced from that gene.
Thus, the mechanisms that best accounts for the difference in the sizes of the mRNAs is the alternative slicing mechanism.
Answer:
1. the cause of magnetic pole reversals
2. the year the next magnetic reversal will take place
4. the exact location of the next earthquake along the California coast
Explanation:
Due to magnetic striping patterns, the magnetic pole of earth go in reverse direction. When the magma comes out from the ocean floor so it spreads on the ocean floor making new bands. So these new bands that spreads the ocean floor make a new floor which change the polarity of the ocean floor in opposite direction. Due to this magnetic striping, the magnetic reversal will take place in which polarity of the earth crust reverses.
