The cell needs transcription because the DNA cannot leave the nucleus and therefore cannot transmit info to the other cells.
1. SI,
2. Number 10.
I'm pretty sure it's that, I just did something related to that.
The answer is C. Protons have an electrical charge
The three nucleotides are the bases used to encode an amino acid of codon.
<u>EXPLANATION: </u>
Genetic code explains the bases and flow in DNA followed by the flow of amino acids present in the proteins.Proteins are usually made of 20 amino acids that has been encoded by four bases. Now, at least three bases are required to encode 20 amino acids.
Three adjacent nucleotides forms a unit called codon. Also, experiments have been done to show that the single amino acid encoded by a group of three bases. This code doesn't overlap with others and the order of flow is read sequentially without any punctuation.
