Answer:
True statements about transcription:
- Occurs in the nucleus
- Produces single-stranded mRNA using the antisense DNA strand as a template
- Precedes 5' capping and polyadenylation.
Explanation:
Transcription is the process by which a specific fragment of DNA (e.g., a gene) is used as template to synthesize a complementary RNA sequence, usually a messenger RNA (mRNA) molecule, which is then used to synthesize a protein in the ribosomes by a process called 'translation'. In eukaryotic cells, transcription occurs within the cell nucleus which contains the genetic material of the cell. Transcription factors are proteins that bind to DNA regulatory elements (e.g., promoter sequences) located at the 5′ end of the transcription initiation site and thus stimulate transcription. Both mRNA capping (5' cap) and polyadenylation are post-transcriptional modifications that serve to protect the nascent mRNA from enzymatic degradation and help in ribosome binding during translation.
The answer would be b, because every time the flowers would cross over it would result in a purple flower.
What are the choices....I would say the sea because I really don't understand what your trying to ask
You dont have options so Ill tell you what I know, animals and bugs become immune to things over time for their survival, the good gene is more likely to be passed on and the bugs with the bad gene are going to be the ones that die off. This process is called natural selection. But there is another thing too, over time scientists have created artificial selection, where you choose desirable traits for a living thing. Such as color, size, flavor, resistance to pests, etc.
