If there are 12 nucleotides how many mrna codons are there?
If there are 12 nucleotides, the number of mRNA codons can be calculated by dividing the total number of nucleotides by 3, since each codon consists of 3 nucleotides. Therefore, with 12 nucleotides, there would be 12 / 3 = 4 codons.
How is dna made into mRNA?
DNA is not made into mRNA, it is transcribed by mRNA. The DNA molecule is split into two strands by the enzyme helicase. One strand is the sense strand and the other is the anti-sense strand. Then mRNA nucleotides pair with their complimentary DNA bases on the antisense strand. The enzyme RNA polymerase causes the mRNA nucleotides to bond with one another, forming a strand of mRNA.
Which molecule would you expect to find codons?
Codons are groups of three nucleotides on the mRNA strand. Codons are bound to the ribosomes where they are met by tRNA's anticodons. Together, the codons and anticodons form amino acids which bind together via peptide bonds and form amino acid chains known as polypeptides or proteins. These proteins are released into the cell to perform their desired functions.
If the strand of DNA has the nucleotides TACCGGACCTGAAGT what would the mRNA strand be?
First of all, it is codons,not condons. MRNA would have uug auc cca. If I am not incorrect, you only use the term codons for MRNA, not in the actual DNA strand. The Anticodons would then be in the TRNA, which codes for the Amino Acids needed by the cells.
What molecule contains all of the codons needed to produce a particular polypeptide?
A single mRNA molecule has 3 codons i.e. 1 amino acid. The question is flawed and does not make sense!
How many codons are there in an mRNA with 75 nucleotides?
Every codon is three nucleotide pairs, so you would have 25 codons.
How many codons are present on the mRNA strand?
There are 6 codon here. Look at the letters and put them into threes. Those three are called codons. Each codes for one amino acid and all of these is a string of threes which will make a small protein.
What happeneds in synthesis?
First, the DNA polymerase makes a copy of the DNA. The nucleotides then bond together and form a complete mRNA strand. The mRNA strand travels out to the cytoplasm through the nucleus. The mRNA is then met by a ribosome and tRNA. Codons and amino acids are then created. After the tRNA detaches from the mRNA strand, the amino acids are connected by a polypeptide bond. This results in a protein. So basically... Protein synthesis is going from DNA to mRNA to tRNA to a protein.
If a section of mRNA contains 144 nucleotides how many codons does it contain?
Codons are read in triplets (3) so divide 144 by 3

Would the codons in figure 8.13 be found in a strand of DNA or rna?
The codons in figure 8.13 would be typically found in a strand of RNA. Codons are specific sequences of three nucleotides that are read by the ribosome during protein synthesis to determine the amino acid that needs to be added to the growing polypeptide chain. In DNA, these codons represent the information that is transcribed into mRNA before being translated into proteins.

How many nucleotides would it take to construct the mRNA coding strand of the β-subunit of the hemoglobin A molecule?
441 nucleotides
How is DNA copied and made into a mRNA?
There is no such process. DNA cannot come from RNA unless it contains reverse transcriptase. However, there is a process that makes mRNA from a DNA strand. This process is called transcription.
Is a strand of mRNA short?
That depends on the type of protein it needs to make. Bigger the polypeptide, longer the mRNA.
