Among the newly-discovered small noncoding RNAs, one type reestablishes methylation patterns during gamete formation and blocks expression of some transposons. What are these types of RNA called

Answers

Answer:

piwi-interacting RNAs (piwi-RNAs)

Explanation:

The piwi-interacting RNAs (piRNAs) are small non-coding RNAs (from 21 to 31 nucleotides) that are abundantly expressed in the animal germline in order to control the expression of target sequences. The piRNAs associate with PIWI proteins from the Argonaute family (AGO) to form an effector complex that binds to complementary target DNA/RNA sequences. These small ncRNAs target Transposable Element (TE) transcripts to suppress TE expression and thus maintain genome integrity. The piRNAs can also guide epigenetic remodeling complexes that suppress gene expression by methylation of target DNA sequences in the nucleus.

Write your question here (Keep it simple and clear to get the best answer) what name iz give to the female part of the flower?

Answers

Answer:

The female part of the flower is called gynoecium or pistil

Explanation:

The female part of a flower is called the gynoecium or pistil. The pistil is located in the center of the flower and consists of three parts: the stigma, style, and ovary.

The stigma is a sticky knob-like structure located  at the top of the pistil. It is covered with a sticky substance so pollen grains will stick to it. It is attached to the long, tubelike structure called the style.

The style is a long  long tubelike structure which connects the stigma to the ovary. The style provides the pathway through which the pollen grains will travel to the ovary in order to fertilize the eggs or ovule

The ovary is the enlarged portion of the pistil found at the base of the pistil. It contains the eggs or ovules.  After fertilization, the ovary develops into the fruit and the ovules become seeds. Based on where the ovary of a plant is located, a plant can be classified as having a superior ovary, an inferior ovary or a half-inferior ovary.

Staphylococcus aureus, or staph, is a bacteria that is commonly found in the nose and on the skin of humans. While it is typically not harmful to humans, it is sometimes able to enter the body through an injury or broken skin, and get into the bloodstream. When this happens, it can cause a serious infection called sepsis. Sepsis can cause an individual to go into shock and bodily organs to stop functioning. Symptoms of sepsis include inflammation, fever or hypothermia, increased heart rate, and rapid breathing.
