Heterozygous, because there are two different alleles for one trait.
Answer:
D. RNA Polymerase
Explanation:
The enzyme RNA Polymerase is present during transcription, which is the process where DNA is transcribed into RNA to be later translated and give a protein. During transcription, RNA Polymerase synthesizes DNA using a strand of DNA as a template. In other words, it transcribes the DNA into RNA.
During replication, one strand of the DNA is replicated using a DNA strand as a template. The result is a new cell with the same information as the original cell. In this process, there is not RNA synthesis. If there is no RNA synthesis, there is no RNA polymerase.
<span>Cardiac cells unlike all the other cells in the body have a branching morphology another unique feature are the intercalated disks between the muscle fibers which skeletal muscle cells do not have they do both have myofibrils though.</span>
heat is a disgusting gacha heat...... joke
Heat describes the transfer of thermal energy between molecules within a system and is measured in Joules. Heat measures how energy moves or flows. ... Temperature describes the average kinetic energy of molecules within a material or system and is measured in Celsius (°C), Kelvin(K), Fahrenheit (°F), or Rankine (R)
Mutation causes Genetic Variation in virus or any other organism !!
so D is your answer !!
