Answer:
Polycythemia Vera
Explanation:
Polycythemia Vera can be described or known to be a type of blood cancer. And its effect is that, it makes the bone marrow to make or produce too many red blood cells, which can thicken the blood, slowing its flow, and can cause serious problems, such as blood clots, strokes, weakness among others.
Some of the symptoms of Polycythemia vera are
* Headaches, dizziness, and weakness.
* Shortness of breath and problems breathing while lying down.
* Feelings of pressure or fullness on the left side of the abdomen due to an enlarged spleen (an organ in the abdomen)
* Double or blurred vision and blind spots.
In conclusion, it should be understood that there is no cure for polycythemia vera. And treatment only focuses on reducing the risk of complications.
Answer:
Explanation:
The genes in DNA encode protein molecules, which are the "workhorses" of the cell, carrying out all the functions necessary for life. For example, enzymes, including those that metabolize nutrients and synthesize new cellular constituents, as well as DNA polymerases and other enzymes that make copies of DNA during cell division, are all proteins.
In the simplest sense, expressing a gene means manufacturing its corresponding protein, and this multilayered process has two major steps. In the first step, the information in DNA is transferred to a messenger RNA (mRNA) molecule by way of a process called transcription. During transcription, the DNA of a gene serves as a template for complementary base-pairing, and an enzyme called RNA polymerase II catalyzes the formation of a pre-mRNA molecule, which is then processed to form mature mRNA (Figure 1). The resulting mRNA is a single-stranded copy of the gene, which next must be translated into a protein molecule.
During translation, which is the second major step in gene expression, the mRNA is "read" according to the genetic code, which relates the DNA sequence to the amino acid sequence in proteins (Figure 2). Each group of three bases in mRNA constitutes a codon, and each codon specifies a particular amino acid (hence, it is a triplet code). The mRNA sequence is thus used as a template to assemble—in order—the chain of amino acids that form a protein
But where does translation take place within a cell? What individual substeps are a part of this process? And does translation differ between prokaryotes and eukaryotes? The answers to questions such as these reveal a great deal about the essential similarities between all species.
Yes, it’s possible. The genetic that they give out to their children depends. If the parents gives out the genes for colorblind for the daughter but not the son, it’s possible.
It’s just like having a child with disabilities and another child that is perfectly healthy.
