Answer:

The vitamin D receptor (VDR) is present in mammary gland, and VDR ablation is associated with accelerated glandular development during puberty. VDR is a nuclear receptor whose ligand, 1,25-dihydroxyvitamin D [1,25-(OH)(2)D] is generated after metabolic activation of vitamin D by specific vitamin D hydroxylases. In these studies, we demonstrate that both the VDR and the vitamin D 1-alpha hydroxylase (CYP27B1), which produces 1,25-(OH)(2)D are present in mammary gland and dynamically regulated during pregnancy, lactation, and involution. Furthermore, we show that mice lacking VDR exhibit accelerated lobuloalveolar development and premature casein expression during pregnancy and delayed postlactational involution compared with mice with functional VDR. The delay in mammary gland regression after weaning of VDR knockout mice is associated with impaired apoptosis as demonstrated by reductions in terminal deoxynucleotidyl transferase-mediated deoxyuridine nick-end labeling staining, caspase-3 activation and Bax induction. Under the conditions used in this study, VDR ablation was not associated with hypocalcemia, suggesting that altered mammary gland development in the absence of the VDR is not related to disturbances in calcium homeostasis. Furthermore, in the setting of normocalcemia, VDR ablation does not affect milk protein or calcium content. These studies suggest that the VDR contributes to mammary cell turnover during the reproductive cycle, and its effects may be mediated via both endocrine and autocrine signaling pathways. Unlike many mammary regulatory factors that exert transient, stage-specific effects, VDR signaling impacts on mammary gland biology during all phases of the reproductive cycle.

Answer:

the simplest bacteria relate to the most complex animal because organisms share the same DNA bases.

Explanation:

Deoxyribonucleic acid (DNA) is a double helix molecule that contains the genetic material of all organisms by which their cells can synthesize proteins.

The genetic material (DNA) passes across generations from parents to offspring to be used by cells to carry out all metabolic functions (e.g., growth, reproduction, differentiation, etc)

• In DNA, there are the same four types of nucleotides in all types of cells, each one containing one different nitrogenous base (i.e., Adenine, Guanine, Cytosine and Thymine).

The simplest bacteria relate to the most complex animal, as all organisms share common DNA bases. The correct option is B.

All creatures have a double-helix molecule called deoxyribonucleic acid (DNA), which serves as their genetic blueprint and allows their cells to produce proteins. Four bases are found in both DNA and RNA, and they are connected by hydrogen bonds.

While DNA has timing and RNA has uracil in place of thymine, all other bases are the same. The base pairs are compatible with one another. Cells require the genetic material (DNA) passed down from parents to children to perform all metabolic processes (e.g., growth, reproduction, differentiation, etc).

All types of cells have the same four types of nucleotides in their DNA, each of which has a unique nitrogenous base (i.e., Adenine, Guanine, Cytosine and Thymine).

Therefore, the correct option is B. all organisms share common DNA bases.
