DNA starts off on the nucleus where it then gets separated into DRNA so that it can travel to other parts of the cell. It is the. Carried by vehicle to the rough ER where ribosomes are added to it then it goes to the smooth ER where waste is expelled. Finally, it goes to the Golgi apparatus where it is either stored or carried to a part of the cell.
This question is incomplete; here is the complete question:
_____ is work done to keep equipment in good working order.
A. Defragmentation
B. Preventive maintenance
C. Virus protection
D. A maintenance schedule
The correct answer is B. Preventive maintenance
Explanation:
Maintenance refers to the processes done on machinery or equipment to preserve its proper functioning. Moreover, this maintenance is preventive if it is done to prevent equipment from breaking down or having any malfunctioning. Besides this, preventive maintenance is globally recommended because in this way equipment used at home or in business works properly. According to this, the correct answer is preventive maintenance.
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>.
Answer:
A
Explanation:
i got it right on edgenuity
Heat given off by the sun would give the cell energy aswell as the nutrients therefore the rate of cell division would be higher. the prediction could be tested by putting algae I'm both the places and recording the rate of cell division
