Answer: It is important that we use our natural resources so that we use any bad things for our earth
Explanation:
Plant Root and Shoot System. Plants have two Organ Systems: the shoot system and the root system. Stems have many jobs, including supporting the plant; acting like the plant's plumbing system, conducting water and nutrients from the roots and food in the form of sugar (glucose) made in the leaves to other plant parts.
no hydrophobic and hydrophilic refer to phospholipids in the cells membrane. A nonpolar molecule is a molecule which has no separation of charge, so no positive or negative poles are formed. In other words, the electrical charges of nonpolar molecules are evenly distributed across the molecule.
Answer:
The best possible outcome for the cell in the event of mis-copied mRNA is for the mis-copied sequence to code for the same amino acid as the correct sequence would have done
Explanation: The process of transcription during which the message in DNA is transcribed as genetic codes into mRNA is sometimes not error proof. Synthesized mRNA is usually transported into the cytoplasm where the codes are translated into protein.
Each genetic code which is usually a sequence of 3 purine/pyrimidine bases codes for an amino acid. However, due to the degenerate nature of the genetic codes, more than one codon can code for the same amino acid. The degenerate nature is caused by the fact that there are 64 possible codons and there are 20 amino acids in nature. For example, UUA, UUU and UUG can be coding for the same amino acid in nature.
Hence, if a mistake occur during transcription, the best possible scenario for the cell is that the mis-copied sequence will end up coding for the same amino acid(s) as the correct correct sequence would.
If siRNA against a starch-branching enzyme was transmitted to humans, then it may affect the expression of glycogen-branching enzymes. RNAi inhibits gene expression.
Glycogen-branching enzymes are similar to starch-branching enzymes because glycogen bonds are similar to those observed between amylopectin.
The RNA interference (RNAi) pathway is an evolutionarily conserved mechanism used in molecular biology laboratories to inhibit the expression of target genes.
In the RNAi technique, a regulatory non-coding RNA called small interfering RNA (siRNA) that exhibits sequence complementary to the target gene sequence is used to inhibit and/or block the translation of the target mRNA (in this case, starch/glycogen-branching mRNA coding enzyme).
