Asexual reproduction is a process wherein cells produce genetically identical offspring.
Since asexual reproduction is when offspring are produced from a single parent, the offspring are identical to the parent. Sometimes, asexual reproduction is called cloning. Cloning is the production of two identical genetic copies from a single parent cell.
The reaction will occur naturally. Positive voltage means it is a working cell.
The correct answer is: B) recognition of the prokaryotic promoter by RNA polymerase
The similarities between prokaryotic and eukaryotic transcription are that DNA is template used for the mRNA synthesis and that this is process is facilitated by the enzyme RNA polymerase.
One of the difference between this process in eukaryotes and in prokaryotes is the promoter region: eukaryotes contain TATA box and CAT box, while prokaryotes don’t (they have Pribnow box that is similar to the TATA box). Promoter region in prokaryotes is always upstream to the start site, while in eukaryotes it can be downstream.
Answer:
D. Nucleic acids attach to the bases in the DNA.
Explanation:
Transcription begins when an enzyme called RNA polymerase is added to the DNA template and begins a new chain a new chain to produce complementary RNA.
During the RNA synthesis transcription takes place, then the cap and tail is added and then splicing occurs.
RNA polymerase moves from the 3' end to the template strand creating the RNA-DNA double helix or similar the base sequences. This makes a chain with each sugar by the set of bonds called phosphodiaster linkage. Then, the enzyme unwind the DNA and begins the synthesis of RNA.
Therefore, D. Nucleic acids attach to the bases in the DNA.
Hemostasis is a process which would cause for bleeding to halt and is the first step in healing wounds. During hemostasis, the process that happens first would be vascular spasm. The damaged vessels are constricted which would result to reducing the amount of the blood flowing in the area thus limiting blood loss. This action is stimulated by factors like direct injury to a smooth muscle. This would allow chemicals to be released by the platelets and the endothelial cells. This response would be more effective as the damage is being increased. Also, it occurs more effectively in areas where there are smaller blood vessels.
