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.

Answer
Yes, Gran stain is a useful tool for unterstanding the phylogeny of eurobacteria.
Explanation
The Gram staining method is used to classify two broad groups: gram-positive and gram-negative bacteria. This technique is widely used in clinical analysis and microbiology laboratories to monitor infections in pus smears or organic fluids.
In the Gran staining method, we subject the bacteria to dye treatments and, depending on the chemical composition of the cell wall of these bacteria, each one will react differently with the dyes and thus identify them by their biochemical characteristics.
