Explanation:
Water moves from higher potential to lower potential i.e it moves from surounding to the cell.
Coniferous trees because they can stay green all year long. Taiga biome are usually cold and coniferous trees never lose it’s color or leaves.
Answer:
C) no, the final mRNA contains only exons, the introns were removed
Explanation:
Exons are the coding areas while the introns are non-coding areas. Both of these are the sequences of nucleotide within a gene.
RNA splicing is a process which usually occurs as the RNA matures, causing the removal of introns ( non coding areas of the RNA ) i-e they will not be expressed in the final messenger RNA, while exons continue to form covalent bonds with one another to form a mature mRNA.
So in the given scenario, Upon comparison, the mRNA is found to contain 1,000 fewer bases than the DNA sequence because the introns were removed by RNA splicing.
Hence option C) no, the final mRNA contains only exons, the introns were removed is correct.
