Answer:A set of five nitrogenous bases is used in the construction of nucleotides, which in turn build up the nucleic acids like DNA and RNA. These bases are crucially important because the sequencing of them in DNA and RNA is the way information is stored.
Answer:
RNA
Explanation:
Transcription is the first process of protein synthesis and it involves copying the information encoded in the genetic material (DNA) to a RNA molecule. It involves making a complementary strand of mRNA from a DNA template.
The process of transcription commences when an enzyme called RNA polymerase binds to the promoter region of a gene on the DNA, signalling the unwinding of its double-stranded structure. The RNA polymerase then adds nucleotides to the growing RNA molecule, complementary to the ones it reads on the DNA. The RNA synthesized during transcription is called messenger RNA (mRNA).
The mRNA is then used as a template for amino acids synthesis during translation.
I think its C. hormones act on muscles and glands only. Because hormones act on cells, tissues, organs etc. So this is incorrect and the rest of them are correct.
