=5) Do your best to describe in as much detail as you can the complete structure of the DNA
molecule.
The structure of a complete structure of the DNA molecule is that there are two phosphate
groups attached to each other by the four base Adenine, Cytosine, Guanine, and Thymine.
Match each Nitrogenous base with its correct category.

a10) Why do some say DNA resembles a zipper?
Some people say DNA resembles a zipper because during DNA replication, the DNA unzips
like a zipper.
Please put the steps of DNA replication in order.

[Not Answered]
r17) Translation is the process of building the mRNA molecule instructions that is a match of the
original DNA molecule in which is in a condensed code that can be delivered to the ribosome
and then interpreted to build proteins.
a) True
b) False
.
r18) Transcription is the process of the ribosomes reading and interpreting the mRNA code and
producing the amino acid chains that can be used to produce proteins.
a) True
b) False
.

d) tRNA with anticodones match to the codones
of the mRNA strand
.
a27) Name 2 ways the structure of DNA and RNA are different name a 3rd and get 1 bonus point.
RNA is smaller, has only one strand, and has Uracil instead of Thymine
a28) A set of 3 nitrogenous bases that are apart of a set of three nucleotides attached to the DNA
strand is a [Codon].
a29) A set of 3 nitrogenous bases in which are attached to a tRNA that match amino acids to form
the amino acid chains is an [anitcodon]
a30) Ribosomes translate the mRNA message beginning at the start codon and ending at the stop
codon.
a) True
b) False
.
a31) Why is it important that there is a signal to stop the ribosome from translating?
It is important that there is a signal to stop because if there wasn't, the ribosome would keep
translating and would never stop.
a32) the four types of mutations are [insertions], [inversion], [deletions], and [translocation].
r33) A point mutation is a mutation that occurs at a specific point in time within a gene.
a) True
b) False
