Answer:
B
Explanation:
I've had this question before got it right.
Answer: The cell cycle is composed of interphase (G₁, S, and G₂ phases), followed by the mitotic phase (mitosis and cytokinesis), and G₀ phase.
Explanation:
Factories, cars and cigoretes.
All of these things are polluting the air cuasing it to heat up more which is cuasing global warming
Answer:
2. mRNA/ formed from the DNA gene sequence with the help of RNA polymerase
Explanation:
Ribonucleic acid, commonly known as, RNA, is one of the two nucleic acid biomolecule. Three types of RNA exists with varying functions viz: Transfer RNA (tRNA), ribosomal RNA (rRNA), and messenger RNA (mRNA).
- mRNA is a type of RNA that is formed from the DNA gene sequence during transcription with the help of RNA polymerase. It contains codons which determine the correct amino acid sequence for a protein.
- tRNA is a type of RNA formed in the nucleus, which contains anticodons (complementary to mRNA codons) that recognizes mRNA codons and carries corresponding amino acids to the ribosome.
- rRNA is a type of RNA that makes up bulk of the ribosome (organelles for protein synthesis).
