Explanation: To produce a protein, genes from DNA have to be transcripted into RNA-messenger. In other words, in transcription the DNA is rewritten with the RNA nucleotides. So, in this sense, nucleotide A from DNA pairs with nucleotide U for RNA; nucleotide T pairs with nucleotide A; nucleotide C with G and nucleotide G with C.

From the DNA sequences given, we have the following RNAm:

1.) DNA: CCT CTT TAC ACA CGG AGG GTA CGC TAT TCT ATG ATT ACA CGG TTG CGA TCC ATA ATC

RNAm: GGA GAA AUG UGU GCC UCC CAU GCG AUA AGA UAC UAA UGU GCC AAC GCU AGG UAU UAG

8.) DNA: TAC AGA CGG CAA CTC TGG GTG CTT TGT TCT CTT CTC AGT ATC

RNAm: AUG UCU GCC GUU GAG ACC CAC GAA ACA AGA GAA GAG UCA UAG

With the RNAm, its sequence is translated into a sequence of aminoacids. This process happens by reading a group of 3 nucleotides, named codon. Each codon is specific for 1 aminoacids. The translation begins with codon AUG, which is the start codon and ends with another specific codon.

The correspondence of codon and specific aminoacids or stop signal is called genetic code and there is a table we can use to produce the sequence of aminoacids.

The translation process will be:

1.) RNAm: GGA GAA AUG UGU GCC UCC CAU GCG AUA AGA UAC UAA UGU GCC AAC GCU AGG UAU UAG

protein: Met-Cys-Ala-Ser-His-Ala-Ile-Arg-Tyr

2.) RNAm: UCU UGU AUU AUG GAG AAU UGU GAG AUU UCU GGU CGU GAG GCU ACU UGA CCU CGU

protein: Met-Glu-Asn-Cys-Ser-Gly-Arg-Glu-Ala-Thr

3.) RNAm: AUG GAA CCC CUU AUA UGU GCG ACC GAA GCU ACU UAG GCA UGC CAU GAG CGG UAG

protein: Met-Glu-Pro-Leu-Ile-Cys-Ala-Thr-Glu-Ala-Thr

4.) RNAm: AUU UGA GCC AUG GAU CGA AUC UAG AUU AAU GGG UAG

the "dirty dozen" chemicals banned in an international treaty are formally known as persistent organic pollutants, or pops. the united nations environment program provided this background on what they are and what they can do to humans and wildlife.

i hope this

true is the
