Answer:
Evolution accounts for the unity and diversity of living things through adaptation. Unity comes from the adaptation and similarities that all organisms share which is DNA, while diversity comes from descent with modification or natural selection.
The sequence of mRNA for a DNA strand AACGTAACG will be UUGCAUUGC.
Central dogma can be described as a process by which information in the DNA is transcribed into mRNA and then changed into proteins.
For a strand of DNA, a complementary mRNA strand is made in order to decode the information in this strand of DNA into mRNA.
The pairing is done as follows: Adenine pairs with Uracil, and Guanine pairs with Cytosine for forming the mRNA transcripts. The nucleotide thymine is absent in mRNA.
Hence, for the strand AACGTAACG, the mRNA strand will be UUGCAUUGC.

The answer would be C. The mass of the object
Answer:
the pathway will be under-expressed.
- the alpha subunit helps to bind with either GDP or GTP. when the α subunit is bound with GDP, it will be bound to β and γ subunits and thus forms an inactive state for G-protein.
- when the alpha subunit binds with the GTP, it becomes activated and dissociates β and γ subunits.
if G-protein Coupled Receptor is unable from dissociating β and γ subunits, then the pathway will go under expression.
The chemical qualities of the alpha subunit allow it to bind easily to one of two guanine subunits, GDP or GTP. The protein thus has two functional formations. When GDP is bound to the alpha subunit, the alpha subunit remains bound to the beta-gamma subunit to form an inactive trimeric protein.
G-proteins, cAMP, and Ion Channel Opening. The alpha subunit activates adenylate cyclase, in purple, and loses GTP. Adenylate cyclase converts ATP to cyclic AMP, which then activates Protein Kinase, shown in blue. Protein Kinase phosphorylates an ion channel, letting sodium ions rush into the cell.
As a result of the ligand binding to its site on the G-protein-linked receptor, A) the G-protein changes conformation and GTP replaces the GDP on the alpha subunit. ... Inactivation of the alpha subunit occurs when its own phosphorylase activity removes a phosphate from the GTP.
