Answer:
the correct answer is True
If one strand of a DNA molecule has the sequence of bases 5-ATTGCA-3, the mRNA synthesized following the template will be 3-UAACGU-5.
Nucleotides are added to the growing strand one at a time in the precise sequence dictated by the existing template strand. adenine and thymine are always paired with each other in the Watson-Crick DNA model, and cytosine is always paired with guanine.
The nucleotide sequence of DNA serves as a template for the nucleus, where mRNA is synthesised. The RNA polymerase II enzyme is responsible for this reaction's catalysis and needs nucleotide triphosphates as its substrates. Transcription is what happens in the nucleus when DNA is converted into mRNA. The cytoplasmic synthesis of proteins is controlled by the mRNA. The cytoplasm is where the mRNA that is produced in the nucleus attaches to the ribosomes after being transported from the nucleus. The nucleotide sequence of the mRNA serves as a guide for the assembly of proteins on ribosomes. The cytoplasm receives a "message" from the nucleus via mRNA. The nucleotide sequence of the mRNA, which is complementary to the nucleotide sequence of the messenger RNA, encodes the message.

The statement that enzymes need to be produced by cells in large quantities because they are consumed by the chemical reactions in which they participate is False.
<h3>
How much quantity of enzyme is needed in a Chemical Reaction?</h3>
- Between 1 and 10,000 substrate molecules can be catalyzed by an enzyme every second.
- Due to the fact that they do not change throughout reactions, enzymes are only found in trace levels in cells. and they have a strong affinity for their substrate.
- By lowering the activation energy and activating more molecules, they act as the catalyst to make the process easier to happen. Because the enzyme must react with the substrate, the concentration of the enzyme is crucial in chemical reactions.
- When enzymes locate their intended substrate, they seize them, undergo a transformation, and then move on to the subsequent substrate molecule.

The cell theory of course had an important impact on later scientific discoveries as many different hypothesis and scientific discoveries were derived and concluded with the help of basics from this theory.
Pathogen 3 will most likely be a virus with the features seen in the table.
<h3>
What is a Pathogen?</h3>
This is defined as disease causing microorganism and examples include bacteria, virus etc.
Virus doesn't replicate on its own but only when in the living cells of other organisms and has a protein capsid but lacks nucleus.
