What is a Philadelphia chromosome?

Biology
2 answers:
TiliK225 [7]2 years ago

Answer:

"Philadelphia chromosome. A piece of chromosome 9 and a piece of chromosome 22 break off and trade places. The BCR-ABL gene is formed on chromosome 22 where the piece of chromosome 9 attaches. The changed chromosome 22 is called the Philadelphia chromosome."

"The Philadelphia chromosome forms when chromosome 9 and chromosome 22 break and exchange portions. This creates an abnormally small chromosome 22 and a new combination of instructions for your cells that can lead to the development of chronic myelogenous leukemia."

"People aren't born with a Philadelphia chromosome. It happens because of a mistake our bodies can make later in life. The mistake is that a piece of chromosome 9 sticks to a piece of chromosome 22. This mistake leads to a very serious blood cancer called "chronic myeloid leukemia," or CML."

"The Philadelphia chromosome is seen in more than 90% of patients with CML but also in 5% or less of children with ALL (20% of adult ALL) and in 2% or less of children with AML. Different isoforms of the fusion gene may be present in ALL. ALL in a child with the Philadelphia chromosome has a much poorer prognosis."

"Currently, the standard of care in the frontline setting for fit patients is TKI in combination with chemotherapy. Age-adjusted chemotherapy or corticosteroids alone have been used with TKIs in elderly patients with comorbidities with modest long-term benefit."

Increasing the number of stomata per unit surface area of a leaf when atmospheric carbon dioxide levels decline is most analogou
Liono4ka [1.6K]

Increasing the number of stomata per unit surface area of a leaf when atmospheric carbon dioxide levels decline is most analogous to a human

B. putting more red blood cells into circulation when atmospheric oxygen levels decline.

<h3>What are stomata?</h3>

The stomata are apertures in the epidermis, each bounded by two guard cells. There are small openings on the lower surface of the leaves. These pores are called stomata. Loss of water from the stomata creates an upward pull, that is suction pull, which helps in the absorption of water from the roots. That is helpful for the transpiration process. They help in exchange for gases. Any of the tiny pores or openings in the epidermis of leaves and young stems are referred to as a stomate, sometimes known as a stoma, the plural of which is stoma or stomas. On the underside of the leaves, stomata tend to be more numerous. They enable the exchange of gases between the atmosphere outside and the leaf's branching network of interconnected air canals.
