Short Essay
24. Explain the process of replication. Include: Where replication takes place.
Replication is the process where DNA creates an IDENTICAL copy of itself. It
begins with a special enzyme slitting the DNA molecule in half. Once split,
nucleotides in the nucleus match up with each of the base pairs. When
completed, the cell now has two double helix strands of DNA. This process
takes place in the nucleus and is part of the process of Mitosis.
25. Explain the process of transcription and protein synthesis. Include: Where
each takes place and the various components involved! Use back if needed.
Transcription is the process of making a small single strand of mRNA from DNA.
This process takes place in the nucleus and involves the unwinding and splitting
of only a small piece of the DNA molecule. Nucleotides match up with the DNA
with the exception of Uracil being used instead of Thymine. This nRNA molecule
now leaves the nucleus and goes into the cytoplasm for use in protein synthesis.
The mRNA molecule is “read” by a Ribosome and as this takes place, tRNA
brings the matching amino acids to be combined into a polypeptide chain of
amino acids which will then fold into a protein of some sort.
Write the matching strand of DNA
NOT ON FINAL!!!
Replicated
If this replicated strand of DNA was being transcribed into mRNA, what would
the strand be?
mRNA
Use the attached amino acid chart to write the polypeptide strand.
