Answer:
A- Pollen grains are transferred from the stamen's anther to the pistil's stigma.
Explanation:
- An angiosperm is a vascular flowering plant. The flowers contain both male reproductive organ and a female reproductive organ.
- The male part is made up of the anthers and filament. The anthers contain pollen grains which fertilize the female reproductive part through the process of pollination.
- The female reproductive part has the stigma,style and the ovary. The stigma is sticky to enable sticking of pollens grains during pollination and the style develops a tube that transports them down to the ovary for fertilisation.
Pre-mRNA is the polymer is synthesized during transcription, it is different from polymer being copied in having U instead of A.
A DNA fragment is copied into RNA during transcription. Messenger RNA is the term for DNA segments that are translated into RNA molecules that can encode proteins. Non-coding RNAs are RNA molecules that contain copies of additional DNA segments. Only 1% to 3% of all RNA samples are mRNA.
