<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:
To moisten and to protect the airway from stuff like unknown pathogens and infection
Explanation:
The Trachea also known as the windpipe has tons of 'little hairs' called cilia in the epithelium that protect the throat. When someone smokes or breathes in gases it is destroyed and exposes the trachea. But thats another story. :)
Answer:
14 cm
Explanation:
Oh, this is a trick question! The thing is, the plant was <u>already 4 cm </u><u>on Day 0</u>. So from Day 0 - Day 15, the plant actually only grew (18 - 4 =) 14 cm.
They got you this time, but hopefully you know to watch out next time. I hope this helps!
Answer: the answer is B which is stationary
Explanation:
This type of front behaves like a warm front only that it is quiescent because the front barely shifts its position. The weather may also be similar to that of a warm front. The two abutting air masses run almost parallel to the front because none is stronger than the other to cause displacement.
There are a lot of forest management practice that cause harm to the forest ecosystems. On of the most harmful is Clearcutting. Also known as clearfelling, in this forestry almost or all of the trees are cut down. It is synonymous to deforestation. It destroys natural habitats.
