68. Transcription Description
Transcription is the making of a gene sequence.
The mRNA molecule leaves the cell nucleus and
enters the cytoplasm. In the cytoplasm the
mRNA strand is synthesized and it is encoded.
The base pairing is adenine with thymine and
cytosine with guanine. The mRNA strand leaves
the nucleus and goes into a ribosome.
69. Translation Description
In translation a ribosome attaches onto the mRNA
strand. During this process the tRNA molecule
comes in with the anti-codon and places it on the
codons in a specific sequence. In transcription A
went with T and C went with G. But in translation
thymine is replaced with uracil. So the pairing is
adenine pairs with uracil and cytosine with guanine.
As the process goes on the anti-codons form amino
acids and peptide bonds. The amino acids are then
formed into a protein.
