What strand of DNA contains codes for the amino acids that make up a protein?
The messenger RNA (mRNA) strand contains the codes for the amino acids that make up a protein. During protein synthesis, the mRNA strand is used by ribosomes to read the genetic information and assemble the corresponding amino acids.
Why template strand also called antisense?
The template strand is also referred to as the antisense strand because its sequence is complementary to the mRNA transcript that is eventually produced during transcription. While the mRNA transcript is in the sense orientation with codons that can be translated into proteins, the template strand is read in the antisense orientation to ensure accurate base pairing during transcription.
If a portion of a DNA strand has the base sequence ACGACG what will be the base sequence of the mRNA strand transcribed?
That mRNA sequence had to come from the complement to it. Remeber that the sequence is normally read 5' to 3'. The complement that produced it would be seen in the 3' to 5' orientation (reverse) during transcription. Therefore, find the complement source by reading the sequence in reverse and making the following substitutions: a becomes t, u becomes a, g becomes c, and c becomes g. The result is the following DNA source sequence read 5' to 3': ctaagtcgcaatttttggcat.
How is the template strand for a particular gene determined?
The template strand for a gene is determined by the orientation of the gene within the DNA double helix. The template strand is the one that is read by RNA polymerase during transcription to create an mRNA molecule. It is complementary to the coding (non-template) strand and guide the synthesis of the mRNA molecule according to the genetic code.
What is the complementary strandof bases for a strand with the bases TACGTT?
If TACGTT is read 5'-TACGTT-3' then the complimentary strand will read 5'-AACGTA-3'. Since the template strand is traditionally written in the 5' to 3' direction then the complimentary strand, written in the same manner, would be AACGTA not ATGCAA. The four bases, adenine(A), thyamine(T), cytosin(C), and guanine(G) bond together in pairs. A - T, and C - G. They do not pair with any other base unless in the case of RNA, when thyamine is replaced with uracil.
Transcription is the process of what?
Transcription is the process of converting DNA into mRNA. During transcription, enzymes read the DNA sequence and create a complementary mRNA strand that carries the genetic information from the nucleus to the ribosomes for protein synthesis.
How does m-RNA read DNA-CCAGTT?
The messenger RNA (or mRNA) compliment to a DNA strand of CCAGTT would be GGUCAA.
What strand of DNA contains codes for the amino acids that make up a protein?

What would happen if mRNA was read backwards?
You would get ANRm.
If a portion of a DNA strand has the base sequence ACGACG what will be the base sequence of the mRNA strand transcribed?

What is the non template strand?
The difference between the coding strand and the template strand is the coding strand is the strand which contains the coding genes, i.e. the one in which the RNA polymerase reads and transcribes into mRNA. It must have the promoter sequence in the correct orientation for transcription, as follows:5`-TATAATGCGCGCGCGCGCGCGCGC-3`3`-ATATTACGCGCGCGCGCGCGCGCG-5`In this sequence, the top strand is the coding strand, because it contains the promoter (TATAAT) in the correct orientation.However, when transcribed, the mRNA will be as follows:5`-GCGCGCGCGCGCGCGCGCGC-3`This is because the polymerase transcribes from the template strand, on the opposide side to the coding strand, to make it in the same orientation as the coding strand.I hope I have explained it enough for people to understand, however if I haven't please read this article I found which explains it thoroughly:http://www.bio.net/bionet/mm/bioforum/1994-May/008821.html

What is DNA sense?
The plus strand is the same as the sense strand and can also be called the coding or non-template strand. This is the strand that has the same sequence as the mRNA (except it has Ts instead of Us). The other strand, called the template, minus, or antisense strand, is complementary to the mRNA. Gotta love the use of 4 names to describe the same thing. Ah science, why do you torment us?
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.

What is the mRNA for DNA molecule t-a-c- c- g -g?
If a DNA strand read CCTAGCT, its mRNA would read GGAUCGA.
