Where does the process of translation do in mRNA?
The newly spliced mRNA binds to a ribosome. tRNA molecules migrate towards the ribosome, these tRNA molecules carries a specific amino acid. The ribosome allows two tRNA molecules into the ribosome at a time. The tRNA molecules have complementary anti-codons to the codons present on the mRNA strand. Two tRNA move into the ribosome and their anti-codons join to complementary codons on the mRNA strand. As one molecule leaves the ribosome, its amino acid forms a peptide bond with an amino acid on the adjacent tRNA molecule, with the help of ATP and an enzyme. As the ribosome moves along the the mRNA strand, a polypeptide chain is created. The ribosome stops reading the mRNA strand when it reaches a stop codon.
Which base sequence would be found on the complentary strand of DNA?
AAUUCCGG
How are protein formed within an organism?
Proteins are formed through transcription, translation, and protein synthesis. In transcription, where a strand of DNA is read by mRNA polymerase, which copies the DNA codes (adenine, thymine, guanine, and cytosine) by making their opposites (ex. DNA strand has thymine, so mRNA strand has adenine, but thymine is NOT on mRNA but is instead called uracil). Next in translation, the mRNA leaves the cell's nucleus. The codons on the strand (set of 3 nucleobases, ex. UUU or AAA, etc.) call for an anticodon (a set of codons carrying a protein) to attach to it. For instance if a codon is read UUU, then the anticodon carried the AAA protein. Another example, if the codons read AUG, the anticodon reads UAC. The anticodons bring in proteins until the mRNA has no more codons to copy. And thats how proteins are made in organisms.
When Chargaff separated the parts of a sample DNA what did he find out about the matching bases?
Because of the asymmetry in pyrimidine and purine use in coding sequences, the strand with the greater coding content will tend to have the greater number of purine bases (Szybalski's rule). Because the number of purine bases will to a very good approximation equal the number of their complementary pyrimidines within the same strand and because the coding sequences occupy 80-90% of the strand, there appears to be a selective pressure on the third base to minimize the number of purine bases in the strand with the greater coding content and that this pressure is proportional to the mismatch in the length of the coding sequences between the two strands. The origin of the deviation from Chargaff's rule in the organelles has been suggested to be a consequence of the mechanism of replication. During replication the DNA strands separate. In single stranded DNA, cytosine spontaneously slowly deaminates to adenosine (a C to A transversion). The longer the strands are separated the greater the quantity of deamination. For reasons that are not yet clear the strands tend to exist longer in single form in mitochondria than in chromsomal DNA. This process tends to yield one strand that is enriched in guanine (G) and thymine (T) with its complement enriched in cytosine (C) and adenosine (A), and this process may have given rise to the deviations found in the mitochondria. Chargaff's second rule appears to be the consequence of a more complex parity rule: within a single strand of DNA any oligonucleotide is present in equal numbers to its reverse complementary nucleotide. Because of the computational requirements this has not been verified in all genomes for all oligonucleotides. It has been verified for triplet oligonucleotides for a large data set. Albrecht-Buehler has suggested that this rule is the consequence of genomes evolving by a process of inversion and transposition. This process does not appear to have acted on the mitochondrial genomes. Chargaff's second parity rule appears to be extended from the nucleotide-level to populations of codon triplets, in the case of whole single-stranded Human genome DNA A kind of "codon-level second Chargaff's parity rule" is proposed as follows: Codon populations where 1st base position is T are identical to codon populations where 3rd base position is A: « % codons Twx ~ % codons yzA » (where Twx and yzA are mirror codons i.e TCG and CGA). Codon populations where 1st base position is C are identical to codon populations where 3rd base position is G: « % codons Cwx ~ % codons yzG » (where Cwx and yzG are mirror codons i.e CTA and TAG). Codon populations where 2nd base position is T are identical to codon populations where 2nd base position is A: « % codons wTx ~ % codons yAz » (where wTx and yAz are mirror codons i.e CTG and CAG). Codon populations where 2nd base position is C are identical to codon populations where 2nd base position is G: « % codons wCx ~ % codons yGz » (where wCx and yGz are mirror codons i.e TCT and AGA). Codon populations where 3rd base position is T are identical to codon populations where 1st base position is A: « % codons wxT ~ % codons Ayz » (where wxT and Ayz are mirror codons i.e CTT and AAG). Codon populations where 3rd base position is C are identical to codon populations where 1st base position is G: « % codons wxC ~ % codons Gyz » (where wxC and Gyz are mirror codons i.e GGC and GCC).
When does translation end?
Translation ends when a stop codon is reached. The stop codons are: * UAA * UAG * UGA
Would the codon in figure 8.13 be found in a strand of DNA or rna?
We can't answer as we do not know what book you are referring to.
Where are codons and anticpdpns found?
Codons are found on messenger RNA, while anticodons are found on transfer RNA
Are codons and anticodons found in DNA?
I think codons are found on dna. Anticodons are found only on trna.

USS UGA or UAG codons found at the ends of mrna?
termination codons
Uaa uga or uag codons found at the end of mrna?
termination codons
On what structure is the codon found?
A codon consists out of a 3 nucleotid long DNA piece. That 3 nucleotids code for an amino acid.
What complementary strand of DNA would be produced from the strand DNA shown below?
Assuming it's 5' to 3', The complementary strand would be 3' G-A-A-T-C-C-G-A-A-T-G-G-T 5'
Can you use the word strand in a sentence?
The DNA strand contains the genetic information needed for cellular function.
A segment of DNA has the following sequence TTAAGGCC. Which sequence of bases would be found on the complementary strand of mRNA?
The complimentary strand of MRNA would be AAUUCCGG.
What nucleotide sequence would be found on the partner DNA strand of the strand shown ACTGT?
The complementary (partner) strand to the segment ACTGT would be TGACA. This is because in DNA, A binds to T and C binds to G.
Are codons found in eukaryotes?
Eukaryotes are cells in which DNA is contained in a nucleus. Codons describe sections of 3 base pairs in DNA which code for an amino acid. So, anything with DNA has codons, therefore eukaryotes have codons.
