C) ribosomes and mitochondria
The correct answer is B. Ribosome
Explanation:
In biology, cells are mainly classified as eukaryotic or prokaryotic. Each of these types of cells has different features, to begin with, eukaryotic cells are those that contain a defined nucleus and are part of both unicellular and multicellular organisms. On the opposite, prokaryotic cells do not have a defined nucleus or a nuclear envelope and are mainly present in unicellular organisms, besides this, they lack mitochondrion, Golgi apparatus or chloroplasts that are present in eukaryotic cells. However, prokaryotic cells still contain DNA, ribosomes, vesicles, and vacuoles. According to this, the one that is present in a prokaryotic cell is ribosome.
The nicotine indirectly inhibit the CB1 or also known as the
Cannabinoid receptor type 1, which is the one responsible in obesity and
metabolic syndrome, thus, this would explain the weight gain associated with
people who quit smoke as if this is indirectly inhibited, it produces weight
gain.
1) ctg act gct aat (you are correct)
2) GAC UGA CGA UUA
* remember for mRNA, a pairs with u
3) Aspartic Acid (Asp), Arginine (Arg), Leucine (Leu)
4) substitution (t changed to g)
Explanation: from GAC TGA CGA TTA
to GAC GGA CGA TTA
5) new mRNA strand: CUG CCU GCU AAU
6) yes, because the amino acids changed, which will code for different proteins.
Hope that helped! And your teacher did a really bad job forming this question, like how there is no starting codon and (no clarity) you don’t know which DNA sequences to use.
