Protine Synthesis is explained below. The answer is in understanding the process itself.
This process can be divided into two parts:
1. Transcription
Before the synthesis of a protein begins, the corresponding RNA molecule is produced by RNA transcription. One strand of the DNA double helix is used as a template by the RNA polymerase to synthesize a messenger RNA (mRNA). This mRNA migrates from the nucleus to the cytoplasm. During this step, mRNA goes through different types of maturation including one called splicingwhen the non-coding sequences are eliminated. The coding mRNA sequence can be described as a unit of three nucleotides called a codon.
2. Translation
The ribosome binds to the mRNA at the start codon (AUG) that is recognized only by the initiator tRNA. The ribosome proceeds to the elongation phase of protein synthesis. During this stage, complexes, composed of an amino acid linked to tRNA, sequentially bind to the appropriate codon in mRNA by forming complementary base pairs with the tRNA anticodon. The ribosome moves from codon to codon along the mRNA. Amino acids are added one by one, translated into polypeptidic sequences dictated by DNA and represented by mRNA. At the end, a release factor binds to the stop codon, terminating translation and releasing the complete polypeptide from the ribosome.
One specific amino acid can correspond to more than one codon. The genetic code is said to be degenerate.

Where are genes found in the nucleus?
in DNA which codes RNA which is then sent out the pores of the nucleus so it can produce proteins for cells.
Why does influenza have RNA?
Influenza has RNA because it steals DNA/RNA from host cells. Proteins also help infect the DNA/RNA.
What types of cells contain RNA and DNA?
Genetic cells
Is DNA found in the nulcei of all cells?
Not all cells have a nucleus. Also nuclei is plural many cells only have one nucleus. Generally cells that have a nucleus have DNA in it. It is suspected that originally the nucleus of cells had RNA instead of DNA and it is suspected that some cells still have RNA in their nucleus. A number of viruses use RNA instead of DNA.
Does transcription occur in DNA or RNA?
Transcription occurs in DNA to produce mRNA.
What is the important of the cells ability to copy single DNA sequence into RNA?
The ability to copy a single DNA sequence into RNA makes it possible for a single gene to produce hundreds or even thousands of RNA molecules.
Where is DNA and rna found?
In prokaryotic cells, DNA and RNA are both found in the cytoplasm. In eukaryotic cells, DNA is typically restricted to the nucleus and RNA is mostly in the cytoplasm.
Where are genes found in the nucleus?

What is the importance of a cells ability to copy a single DNA sequence into rna?
(Short Version) RNA makes it possible for a single gene to produce hundreds/ thousands of RNA molecules. -Gina(:

What contains ribose RNA or DNA?
Cells in living organisms, including bacteria, contain DNA.
Cells store genetic information in DNA. That genetic information is used to synthesize .?
cells store genetic information in dna. that genetic information is used to synthesize
Which cells have DNA as their genetic material?
Haploid cells like sperm cells,ova,bacteria
Does transcription occur in DNA or RNA?
Transcription occurs in DNA to produce mRNA.
Why are the RNA viruses not able to package DNA?
The RNA virisus's cells do not have a Golgi Complex, so they do not have the ability to package DNA.
