Answer:
The corresponding RNA would have "CUG" in place of "CUA"
Explanation:
The nucleotide sequence of the DNA template strand determines the sequence of RNA and the nucleotide sequence of mRNA specifies the amino acid sequence of the protein. Guanine in DNA template pairs with cytosine, adenine with uracil and thymine with adenine base in the RNA.
A DNA template strand with sequence "GAT" would specify the sequence "CUA" in the corresponding DNA. If "T" in the sequence of template strand is replaced with "C", then the corresponding RNA would have sequence "CUG".
However, amino acid leucine has a total of six codons: UUA, UUG, CUU, CUC, CUA, and CUG. Therefore, both the mRNA would code for the same amino acid.
Answer:
1st one
Explanation:
DNA replace the old cells
After crystal violet staining, the Gram-positive bacteria may appear dark blue or violet. The cell wall of gram positive bacteria have thick peptidoglycan layer, thus it retains the crystal violet stain compared to gram negative bacteria.
Hope this helps! Have a good day!
<span>The correct answer is B.exocrine glands.
It is because exocrine glands do not belong to the neuroendocrine system.</span> <span>The neuroendocrine system integrates the interaction between the nervous system and the endocrine system to regulate the physiological processes of the human body (homeostasis, reproduction, metabolism, osmolarity, energy regulation, blood pressure). The major systems within neuroendocrinology systems are hypothalamic–pituitary–adrenal axis, hypothalamic–pituitary–thyroid axis,hypothalamic–pituitary–gonadal axis.</span>
The correct answer is C. Tissue
Explanation:
In the diagram, x is between organ and cell level. This implies this level of organization is smaller than an organ but no as small as one cell. In this context, the most suitable term to add to this level is a tissue because these are structures composed of specialized cells, which shows this level encloses cells. Also, a group of tissues forms an organ; this implies the organ is the level that follows the tissue. Examples of this include muscle tissue composed of muscle cells and that is part of organs including the heart.
