Answer: Acceptor stem and anticodon loop.
Explanation:
Transfer RNA (tRNA) is a small RNA nucleic acid involved in protein synthesis (translation). Each tRNA molecule has two important areas:
- A region of trinucleotides, called the anticodon
- A region where a specific amino acid binds.
<u>During translation, the ribosome reads the sequence of the mRNA in groups of three bases to assemble the protein</u>. So, in the mRNA chain there are codons, set of three bases, which determine the amino acid to be added to the peptide chain. <u>The tRNA transfers the amino acid</u> to the ribosomes, and then arranges them along the messenger RNA (mRNA) molecule. <u>Then, the tRNA must have an anticodon that is complementary to the codon.</u> Each type of tRNA is specifically combined with 1 of the 20 amino acids to be incorporated into proteins.
This means, during translation, each time an amino acid is added to the growing chain, <u>a tRNA molecule is formed whose base pairs have a complementary sequence with mRNA molecule</u>, ensuring that the appropriate amino acid is inserted into the protein. So, tRNA is a key link between RNA transcription and the translation of that RNA into protein. On the other hand, aminotransferases are enzymes responsible for attaching amino acids to the 3ʹ‐end of cognate tRNAs.
The acceptor stem is the site of attachment of amino acids to tRNA, and anticodon loop is the site of tRNA that is complementary to the codons found in mRNA (that determine the amino acid that will be added) This means, both parts are important for recognition, <u>because the acceptor stem is where the amino acid is, and the anticodon loop ensures that the appropriate amino acid is inserted into the protein</u>.
Correct answer: Habitat Destruction
Habitat destruction affect the entire habits functionally and it is unable to support the species present in that particular region. The main cause of species extinction all over the world is habitat destruction.
Humans are known to cause extinction of the species by creating pollution, overhunting, by introducing invasive species into the ecosystem etc
Answer:
True
Explanation:
Do all living organisms have mechanisms for homeostasis?
All living organisms have ways of maintaining homeostasis. They have mechanisms for controlling such factors as their internal temperature, water balance, and acidity.
Answer: Red tide events
Explanation:
Red tide events causing massive fish die-offs, unprecedented sea ice loss, erosion of coastal wetlands, and bleaching of coral reefs not only impact marine ecosystems but also communities, peoples' well-being, local businesses, and more.
These issues impacting ecosystems and people require solutions that consider ecosystems and people. These types of solutions are Ecosystem-Based Management, which considers social, economic, and ecological trade-offs when deciding how to address these issues.
