Answer:
d. tissue
Explanation:
There are several levels of organization of life which starts from the functional unit of life called cell.Cells are made of a combination of macromolecules that consist of atoms. Several cells associate together to perform one or more specific functions at the tissue level. The tissue level is made up of similar cells that carry out similar task or functions. The robot’s cardiac cells that work together in synchrony could be considered at the tissue level.
The process of fusing two or more DNA molecules to produce a hybrid is known as recombinant DNA. Restrictions endonucleases and ligases are two classes of enzymes that enable the technique.
When a restriction endonuclease detects a particular DNA sequence, it makes cuts inside or near that sequence. The recognition sequence of a restriction enzyme will haphazardly appear on every (1–4)n bases along a random DNA chain. The equation states how many fragments ends (measured in moles) are produced when a restriction enzyme cuts DNA.
Moles of DNA ends =2x(grams of DNA)/(number of bp)(660 g/mol / bp).
The equation describes how many ends are produced when circular DNA is digested by a restriction enzyme.
Mole ends=2x(moles DNA)x number of restriction sites.
The following equation can be used to determine how many ends are produced during the digestion of a linear molecule by a restriction endonuclease.
Mole ends=2x(molesDNA)number of restriction sites +[2x(moles of DNA)].

Answer:
Hypothalamus and anterior pituitary gland.
Explanation:
Lower levels of T3 and T4 in the blood or lower metabolic rate serve as signal and stimulate the release of thyrotropin-releasing hormone (TRH) from the hypothalamus. The TRH stimulates the anterior pituitary gland to release thyroid-stimulating hormone (TSH) which in turn makes the thyroid gland to release the thyroid hormones.
The elevated levels of thyroid hormones inhibit the release of TRH from the hypothalamus and that of TSH from the anterior pituitary gland.
Hence, the cells of hypothalamus and anterior pituitary gland would be inhibited by the binding of thyroid hormone to regulate the release of these hormones by a negative feedback mechanism.

Answer:
The correct option is D) UAG, UAA, UGA
Explanation:
The amino acid sequencing code or mRNA code contains specific codes which start and stop the process of translation at the right time. If the stop codon were not present then the ribosomal machinery would have made faulty proteins. If the stop codons are not at the right place, then it results in the production of faulty proteins. The stop codons which terminate the process of translation are UAG, UAA and UGA.
