Step 2 -
Complimentary bases are added to each strand.

As the strands separate, new nitrogen bases (actually nucleotide units) are added by proteins called
DNA Polymerases.


This continues until both strands are completely copied.
Replication Is Complete
(and more)
When the process is over there are two
exact
copies of the DNA molecule.
Why is it important that the copies be identical?
There are about 100 starting points when a human DNA molecule is copied.
It takes about eight hours to copy a human DNA molecule.
Protein Synthesis
Process of reading DNA instructions and making proteins
.

1. Original Source: Larry Flammer, idea developed in 1963 and used in Biology classes ever since, as the finale to a series of Do-It-Yourself DNA Kits (1. DNA Structure & Sub Structure, 2. DNA Replication, and 3. Protein Synthesis, all involving manipulation of cutouts, and resulting in the spelling out of a little 3-letter word (meaningful amino acid sequence).

Drag-and-Drop Protein Synthesis: Overview

Protein Synthesis Practice 2-- practice worksheet of interpretting a different style diagram of transcription and translation ;



Protein synthesis
has two stages:
Transcription
and
Translation
Transcription
is the process of making an
RNA
strand from the DNA.
Translation
is the making of
proteins
from the
RNA
code.
Translate means to change "languages" (from nucleic acids to amino acids)
Transcribe means to make a copy of something from one source to another
Transcription
There are three steps to transcription.
Step 1 - a protein known as
RNA polymerase
attaches to a specific part of the DNA molecule
(the promoter)
.
Step 2 - The
RNA polymerase
unwinds and separates the DNA double helix.
Step 3 -
RNA polymerase matches complimentary bases to
one
of the DNA strands.

The nitrogen base
Uracil
binds to
Adenine
rather than
Thymine.

I mean, replicate the strand of DNA on your desk.
MUTATIONS
Mistakes made during DNA replication or protein synthesis called
mutations
.

All known prions are altered conformational states of "prion protein" (PrP; PRNP; Science 233: 364, 1986), a normal membrane glycoprotein coded in the mammalian genome (* human chromosome 20), and well-conserved over evolution, has its gene transcribed (but does not accumulate) in health (Neurology 40: 518, 1990), and is not homologous to other known proteins.
