Answer:
<em>The correct options are:</em>
<em>Prior to process 1, DNA should copy itself to allow the cell to divide.</em>
<em>Between processes 1 and 2, the mRNA must be modified before leaving the nucleus.</em>
Explanation:
For eukaryotes, the mRNA is made in the nucleus from the DNA. This process in known as transcription. The process of making proteins from the mRNA takes place in the ribososmes of the cytoplasm. This process is known as translation. The mRNA has to be modified before it is transported for translation. Otherwise, the mRNA will be degraded by the enzymes of the nucleus.
It’s Sigmoid Phenomenon aka D
It took the test
The first one is have the refrigerant level checked by a qualified professional. The technician will be checking any possible leak, damage and conduct test on the system. Second is to ensure airflow. Change the filter regularly, usually about every three months or maybe monthly, depending on its usage. Have the coils cleaned by a professional if it is already dirty. The third method is to not use your air conditioner when the outside temperature is below 60º. You will be saving energy and money on utility costs by just opening the windows on cool days.
Answer: RNA is a more stable molecule than DNA
Explanation: DNA (deoxyribonucleic acid) is much stable than RNA (ribonucleic acid) for many reasons; Frist of all its because of the double strand of the DNA versus the single-stranded RNA. This is thanks to the Hydrogen bonding between bases since those bondings release free energy that allows the molecule to be provided by more thermodynamic stability.
Also the lack of 2′ OH groups makes DNA more stable since the OH groups are very reactive by themselves. In the DNA sugar molecule there is not a spare OH group that could start reacting on its own. So this is why DNA is immune to chemical reactions, while RNA (having an extra OH group) is more chemically "promiscuous".
