Bougainvilleas do not have calyx or corolla. Only petaloid perianth lobes are found.

Why is end of a processed mrna referred to a poly a tail?

The poly(A) tail is a long sequence of adenine nucleotides added to the end of a processed mRNA molecule. It plays a role in protecting the mRNA from degradation and regulating its stability and translation efficiency. The addition of the poly(A) tail is an essential step in mRNA processing in eukaryotic cells.


What are the benefits of using poly selection in the manufacturing process?

Poly selection in the manufacturing process offers several benefits, including increased strength, durability, and flexibility of the final product. Additionally, it allows for customization and cost-effectiveness in production.


How are the word parts poly- and genic related to the meaning of the term polygenic traits?

The word part poly- means "many," and genic refers to genes. Polygenic traits are determined by multiple genes, each contributing a small effect to the overall trait. So, the terms poly- and genic in polygenic traits indicate that multiple genes are involved in determining the trait.


What is the purpose of the 5' cap and the 3' poly A tail?

5' cap helps protect mRNA from degradation by hydrolytic enzymes and after mRNA reaches the cytoplasm, the 5' cap functions as part of an "attach here" sign for ribosomes. The poly-A-tail inhibits degradation of RNA and helps ribosomes attach and facilitates export of mRNA from the nucleus.


What is polyadenylation mechanism?

Polyadenylation is a process in which a poly(A) tail is added to the 3' end of a newly synthesized mRNA molecule. This poly(A) tail helps to stabilize the mRNA molecule and plays a role in the export of the mRNA from the nucleus to the cytoplasm for translation. Polyadenylation also signals the termination of transcription.
