Explanation: Teacher gave me the answer
Chromosomes are thread-like structures in which DNA is tightly packaged within the nucleus.
Answer:
Hormones, Cell receptor and glands
Answer:
large central vacuole
Explanation:
mature plant cell contains large vacuoles while a animal cell has small vacuoles
Answer:
The correct answer will be option-D.
Explanation:
In eukaryotes, the process of transcription takes place inside the nucleus whereas translation takes place in the cytosol. So, mRNA has to export to the cytosol from the nucleus.
Before export, the post-transcriptional modification takes place like 5' capping, 3' tailing and splicing mechanism.
The capping is done at 5' end by adding modified guanine (G) nucleotide which protects the mRNA from exonuclease activity and tailing is done at 3' end by adding adenine nucleotides which provides stability to the mRNA.Splicing removes the junk DNA called introns and joins the exons before export.
Thus, option-D is the correct answer.
