When a pathogen or bacteria is recognized by the immune system, the adaptive immune response is activated, leading to the production of two main types of cells: effector cells and memory cells.
a) Effector Cell: Effector cells are responsible for carrying out the immediate response to eliminate the pathogen or bacteria. In the context of the adaptive immune response, there are two primary types of effector cells being Cytotoxic T cells (CD8+ T cells) & B cells.
b) Memory Cell: Memory cells are long-lived cells that "remember" the specific antigen from a previous encounter with a pathogen or bacteria. They are derived from the same activated cells that give rise to effector cells. If the same pathogen is encountered again in the future, memory cells can quickly respond and initiate a faster and more effective immune response.

Most arteries of the adult body carry oxygen-rich blood, and the veins carry oxygen-depleted, carbon dioxide-rich blood. How does this differ in the pulmonary arteries and veins?
The pulmonary arteries carry oxygen-depleted blood from the heart to the lungs for oxygenation, while the pulmonary veins carry oxygen-rich blood from the lungs back to the heart to be pumped to the rest of the body
The pulmonary arteries carry oxygen-depleted, carbon dioxide-rich blood from the right ventricle of the heart to the lungs. They branch out into smaller arteries and eventually into even smaller arterioles, which carry blood to the pulmonary capillaries within the walls of the alveoli in the lungs.
In the pulmonary capillaries, the blood undergoes gas exchange, with carbon dioxide diffusing out of the blood into the alveoli, and oxygen diffusing from the alveoli into the blood. This oxygenates the blood, changing it from oxygen-depleted to oxygen-rich.
After gas exchange occurs in the pulmonary capillaries, the now oxygen-rich blood is collected by small venules, which then join together to form larger pulmonary veins. The pulmonary veins carry oxygen-rich blood from the lungs back to the left atrium of the heart, which then pumps the oxygen-rich blood to the rest of the body.

All of the listed terms (sigma factor, shine-delgarno sequence, promoter, RNA polymerase) would be involved in some part of the process of transcription of a bacterial gene. Transcription is the process by which RNA polymerase reads the DNA template and creates a complementary RNA sequence.
The sigma factor helps RNA polymerase recognize and bind to the promoter region on the DNA template, while the shine-delgarno sequence helps to orient the ribosome during translation of the resulting mRNA.
From DNA, transcription causes the production of RNA. RNA Polymerase executes the procedure by creating an RNA strand from a template DNA strand.
Pre-initiation complex formation is where it all begins. The pre-initiation complex is created when transcription factors and RNA polymerase bind to the DNA promoter region. In most eukaryotic promoters, a region known as the TATA box is where transcription factors first bind. The DNA strands eventually separate, RNA polymerase binds to the area, and transcription is then initiated.

Explain what is meant by genomic imprinting.
Genomic imprinting refers to the process by which certain genes are expressed in a parent-of-origin-specific manner. This means that the expression of the gene depends on whether it was inherited from the mother or the father.
The imprinting of genes is controlled by epigenetic modifications, which can affect the accessibility of the DNA to transcription factors and other regulatory proteins. This process is important for the regulation of fetal growth and development, as well as the maintenance of normal cellular function throughout the lifespan. Examples of imprinted genes include those involved in fetal growth and development, such as insulin-like growth factor 2 (IGF2), and those involved in neurological function, such as brain-derived neurotrophic factor (BDNF).
Genomic imprinting is an epigenetic phenomenon that causes genes to be expressed in a parent-of-origin-specific manner. This means that the expression of a particular gene depends on whether it was inherited from the mother or the father. Genomic imprinting involves DNA methylation and histone modification, which lead to changes in gene expression without altering the underlying DNA sequence.
To summarize, genomic imprinting is a process that regulates gene expression based on the parental origin of the gene, involving epigenetic mechanisms such as DNA methylation and histone modification.
