Answer:
a. eukaryotes have three different RNA polymerases, whereas prokaryotes only have one RNA polymerase
Explanation:
The initiation represents the beginning of RNA production. Initially, RNA polymerase (transcription catalyzing enzyme) recognizes in DNA the so-called promoter regions. In prokaryotes, there is only one type of RNA polymerase; In eukaryotes, three RNA polymerases are described, and thus the transcription process in this group is more complex.
In the initiation step, we also observe the opening of the DNA strand, a process known as unfolding. This opening occurs because of the rupture between the connections that arise between the bases.
Answer:
transcription is the synthesis of an mRNA molecule using a DNA molecule for a template. That mRNA molecule then goes on to complete translation in the ribosome. Translation is the process in which proteins are produced based on instructions carried by mRNA.
Explanation:
Energy from sunlight is being used in an indirect way for walking the dog. Plants photosynthesize in which they absorb energy from sun and convert it into chemical energy, which is stored in organic product formed as a result of photosynthesis. When this organic compound is consumed by us, we use the chemical energy stored in that food to mechanical energy for walking the dog. Hence, the energy to walk the dog comes from sunlight.
The aveolus is surrounded by capillaries. So capillaries carry deoxygenated blood to the alveolus where the oxygen from the alveolus diffuses into the blood in the capillaries. The deoxygenated blood is now oxygenated and is carried out of the lung via capillaries that then merge into the pulmonary vein.
In other words, alveolus does not have oxygenated blood it just puts oxygen into the deoxygenated blood hat this brought in.
<u>Answer:</u>
C. Converting chemical energy from ATP into chemical energy in glucose products.
<u>Explanation:</u>
Mitochondria are known as the powerhouses of a cell, as they are responsible for making ATP, the cell's main energy carrying molecule.
