Among the tasks in coping with life-threatening illness described by Kenneth Doka, the chronic phase is characterized by "living with the disease".
Kenneth Doka (1995–96) divides the process of dying into three phases, namely the acute, the chronic, and the terminal phases of dying, during which the individual initially is given the diagnosis, then lives with the disease and ultimately surrenders to death.
This phase can be quite long and the supporters may become comfortable in their caregiving role and adjust to the notion of death. This is an important adaptation since a great deal of the care for the terminally ill is given by the family members.
Doka (1998) notes that this phase "is often a period of continued stress, punctuated by points of crisis".

Why was the original ""one gene–one enzyme"" hypothesis modified to ""one gene–one polypeptide""?
The original "one gene–one enzyme" hypothesis was modified to " one gene–one polypeptide" because not all proteins are enzymes, and many proteins are built from two or more distinct polypeptide chains.
According to the one gene, one enzyme hypothesis, which was put forth by George Wells Beadle in the US in 1941, each gene directly generates a single enzyme, which then influences a particular stage in a metabolic pathway. Since one gene can produce several proteins and not all proteins are enzymes, the one gene, one enzyme hypothesis of Beadle and Tatum has been amended. We also know that enzymes are made up of many polypeptides. Therefore, "one gene-one polypeptide" has been changed to make the hypothesis more precise.
In contrast to the one gene-one polypeptide hypothesis, which claims that one gene regulates the creation of just one polypeptide chain of an enzyme molecule, the one gene-one enzyme hypothesis states that one gene controls the production of one enzyme.

Answer:

Ovulation Process:
The pituitary gland, located in your brain, releases a hormone once every month. This hormone instructs the ovaries to create many follicles, which are fluid-filled cysts. The hormone oestrogen is secreted by the growing follicles. In order to prepare for pregnancy, oestrogen causes the uterine membrane to thicken.
The follicles cease developing on day seven of your cycle, with the exception of one. This follicle keeps expanding and nourishes an oocyte (egg) that is developing within.
On day 12, a surge of oestrogen is released into the bloodstream by the developing follicle. Your blood carries the oestrogen along. The pituitary gland in your brain releases luteinizing hormone in response to the oestrogen reaching it. This hormone causes a quick growth spike in the follicle.
The egg within the follicle separates from the follicle just before ovulation. The neighboring fallopian tube begins to migrate toward and around the follicle as the follicle begins to produce chemicals.
The egg and fluid are ejected into the abdominal cavity when the follicle expands to the point of breaking open.
Fimbriae, or tiny finger-like projections at the termination of the fallopian tube, move over the ruptured follicle and seize the egg.
The egg is moved to the fallopian tube's opening. Muscle contractions push the egg gently towards the direction of the uterus once it has entered the fallopian tube's walls.
Either sperm will contact the egg as it travels down the fallopian tube, resulting in fertilization, or the egg will arrive in the uterus unfertilized and be reabsorbed into the body.
Conception Process:
A woman must fertilize her egg within the 12 to 24 hours following ovulation if she wants to get pregnant.
The surge of oestrogen right before ovulation also creates the protein-rich transparent jelly that covers the vagina during intercourse within the neck of the uterus (the cervix). Thus, the vagina became acidic (which prevents thrush and other infections). Sperm can survive in this environment as well. Rapidly moving sperm swim up and into the cervix, where they can live for up to five days in the mucus until an egg is produced.
The fallopian tube might grab the egg because it is wrapped in sticky cells when it is released after ovulation. The sperm begin to break down the adhesive cells when they encounter the egg in the fallopian tube. While only one sperm is required to create a baby, numerous are required to cling to the egg's membrane and outer shell before one may penetrate and fertilize it.
After fertilization, substances are produced to prevent the entry of more sperm before the egg and sperm swiftly combine and split to form an embryo.
The fertilized egg continues to divide and move toward the uterus throughout the course of the following four to five days.
The burst follicle (now known as the corpus luteum), which releases the hormone progesterone into your bloodstream, primes the uterus for the egg to implant.
The pregnancy is sending an increasingly potent signal to the ovary to prolong and boost the production of progesterone, which the pregnancy needs to live, while it develops and installs itself into the mother's uterine lining and blood vessels.

If fertilization does not occur, the corpus luteum will become a corpus ________ and eventually disappear
If fertilization does not occur, the corpus luteum will become a corpus albicans and eventually disappear
How the corpus luteum changes if fertilization does not occur?Around 10 days after the egg leaves the dominant follicle, corpus luteum will begin to degrade if the egg is not fertilized. Uterus lining won't undergo the modifications necessary to promote pregnancy without progesterone. Instead, the lining will be lost when you get your period.
The corpus albicans is the regressed version of the corpus luteum, which is referred to as the atretic corpus luteum, corpus candicans, or simply as albicans (Latin for "whitening body"). Fibroblasts deposit type I collagen to create the corpus albicans as macrophages degrade the corpus luteum.
The hormone progesterone, which is produced by the corpus luteum, makes the uterus a healthy environment for a growing fetus. Each time you ovulate, a new corpus luteum develops, and it disintegrates once you no longer require it for progesterone synthesis. The uterus could not transform an egg that has been fertilized into a fetus without the corpus luteum.

In molecular biology, messenger ribonucleic acid (mRNA) is a single-stranded molecule of RNA that corresponds to the genetic sequence of a gene, and is read by a ribosome in the process of synthesizing a protein.
mRNA is created during the process of transcription, where an enzyme (RNA polymerase) converts the gene into primary transcript mRNA (also known as pre-mRNA). This pre-mRNA usually still contains introns, regions that will not go on to code for the final amino acid sequence. These are removed in the process of RNA splicing, leaving only exons, regions that will encode the protein. This exon sequence constitutes mature mRNA. Mature mRNA is then read by the ribosome, and, utilising amino acids carried by transfer RNA (tRNA), the ribosome creates the protein. This process is known as translation. All of these processes form part of the central dogma of molecular biology, which describes the flow of genetic information in a biological system.
As in DNA, genetic information in mRNA is contained in the sequence of nucleotides, which are arranged into codons consisting of three ribonucleotides each. Each codon codes for a specific amino acid, except the stop codons, which terminate protein synthesis. The translation of codons into amino acids requires two other types of RNA: transfer RNA, which recognizes the codon and provides the corresponding amino acid, and ribosomal RNA (rRNA), the central component of the ribosome's protein-manufacturing machinery.
The concept of mRNA was developed by Sydney Brenner and Francis Crick in 1960. While performing the experimental verifications, François Jacob and Jacques Monod coined the name "messenger RNA". In 1961, mRNA was isolated and described independently by James Watson's research team and a team of Jacob, Monod and Matthew Meselson.
