<u>Correct sequential order for the following processes of protein synthesis are as follows:</u>
- DNA strands unwind and separate
-
mRNA copies DNA according to complimentary base pairing
- mRNA leaves the nucleus
- tRNA’s anticodons bring amino acids to the corresponding mRNA codons at the ribosomes
- amino acids bind to each other making a polypeptide
-
a stop codon is reached, the newly formed a protein is released to go do its job for the cell
Option A --> B --> C --> E --> D -->F
<u>Explanation:</u>
Protein synthesis involves three major steps which are Replication of DNA, which is then transcribed and then translated to form protein, so the steps are Replication, Transcription and Translation.
Firstly, the DNA is a double stranded molecule which needs to be unwind as a replica where one of the strand becomes the template strand and transcription of strand occurs with mRNA.
mRNA thus leaves the nucleus and reaches cytoplasm where translation takes places and the tRNA provides specific anti codons to the mRNA codons and the amino acids are formed.
All amino acids bind to each other in order to make a polypeptide and hence the protein molecule newly formed is released to the cell.
Answer:
There are 8 electrons in the outer ring, and has to react with 8 or fewer electrons to form a stable molecule.
Explanation:
The outer-most orbits of silicon contains a maximum of eight (8) electrons. It requires 8 of fewer electrons to form a stable molecule.
Answer:
Active uptake (which I think you mean active transport) is important when the concentration gradient is against that of a certain substance, so it doesn't cross the membrane through diffusion or passive transport. It is sometimes necessary if a substance needs to move across a membrane but can't do so due to electrical charge or that there is a substance on the other side of the membrane preventing diffusion.
Explanation:
Answer;
A) Blood pressure decreases greatly; blood flow to the heart is inadequate, and blood pressure decreases.
Explanation;
-With negative feedback, the output reduces the original effect of the stimulus. While in a positive feedback system, the output enhances the original stimulus.
-Negative feedback is the most commonly used feedback loop in the body. Negative feedback is used to negate or counteract a stimulus without completely eradicating it.
-One key difference between the two feedback is that positive feedback loops are used to eradicate a stimulus. Another key difference is that responses through positive feedback become more amplified over time. So once a stimulus activates a positive feedback loop it is not turned off until the stimulus is completely removed.
