What is the section of DNA being used to make the strand of RNA known as?
The DNA template strand is used to create mRNA.
Section of DNA that forms a particular strand of messenger RNA?
A section of DNA that corresponds to an mRNA is a gene.
What is important about the DNA template strand?
The template and non-template strands of DNA are complementary.This means that if a T (thymine)occurs on one strand, there must be an A (adenine) in that position on the other strand, and that C (cytosine) is always opposite G (guanine), following the rules of complementary base pairing.There are other names for the two strands, but Googling them shows there is a lot of confusion out there! The terms "template strand" and "non-template stand" seem to be the only ones that everyone uses consistently. The template strand is the strand along which messenger RNA is synthesized, and has, of course, a base sequence complementary to that of the RNA.The term "gene" is often applied to the non-template strand, the argument being that the non-template DNA strand and the mRNA have the same base sequence (except that where DNA has T, RNA has U, uracil).In transcription, RNAP uses template strand to make a copy of mRNA. Complementary to template strand is the coding strand, which sequence is identical to mRNA sequence except for the substitution of U for T. Although the coding strand is not used as a template for common transcription events, it is called coding because its sequence is used as a copy in mRNA sequence. For the case of "sense", terminologically template strand is called antisense, and coding strand is called the sense strand.Template/non-coding/antisenseNon-template/coding/senseMany people confuse complementary sequences with palindromic sequence which you can find in restriction system recognition sequences. Although the template strand yields a sense (functional) sequence in mRNA and thus a properly-folded protein, the complementary strand of it, non-template strand upon being transcribed yields a totally different and non-functional protein. However in terms of transcription of palindrome, both strands yield the same mRNA sequence, thus the same protein.Coding strand of a particular gene can be on one of either two strands of DNA, and thus this applies to the opposite strand of the said strand for the non-coding strand. The direction of transcription on a double-stranded DNA depends on whether the upper or lower strand is being transcribed. Therefore on a linearised genome, transcription occurs to the left for certain genes and to the right for the remaining genes.
Why are two different primers required for the polymerase chain reaction?
Must use the forward and reverse primers to bind to complementary sequence at the 3' end of the template strand - each NEW strand is built in 5' to 3' direction. They flank the targeted gene region - must attach one to each strand of the target DNA.
When transcription begins the enzyme is called?
the RNA polymerase attaches to the promoter and transcribes the gene in messenger RNA, or mRNA
What is the section of DNA being used to make the strand of RNA known as?
The DNA template strand is used to create mRNA.
What strand of DNA is used to make a complementary copy or to make a complementary mRNA molecule-?
The strand is called the parental strand. the gene being copied would depend on which protein is needed.
How many strands does mRNA have?
a MRNA strand is a strand made up of messenger ribosenucleicacids
Section of DNA that forms a particular strand of messenger RNA?
A section of DNA that corresponds to an mRNA is a gene.

What is strand of DNA that codes for a specific trait?
A gene is a strand of DNA that codes for a specific trait
Why is it important for a single gene to be able to produce hundreds of thousands of the same RNA molecule?
The sense strand of any gene acts template. It is the master copy (blue print) that is able to produce N number of same RNA at a particular time and place. The entire activity is highly orchestrated and well regulated.
Why it is important which of the two DNA strands serves as a template during the transcription?
lolwut?lolwut? IS NOT AN ANSWER.The answer really is... because only one of the 2 strands has the proper base-sequence information for making the functional RNA or protein. So that strand is called the template strand.
Why are two different primers required for the polymerase chain reaction?
Must use the forward and reverse primers to bind to complementary sequence at the 3' end of the template strand - each NEW strand is built in 5' to 3' direction. They flank the targeted gene region - must attach one to each strand of the target DNA.
Why is one strand of the DNA molecule labeled Template DNA?
DNA acts as a template for two things: # DNA # mRNA transcripts This is possible because each nitrogenous base in one strand pairs only with one other base in the complementary strand as follows: Adenine (A) always pairs with Thymine (T) Guanine (G) always pairs with Cytosine (C) Note: in RNA, Uracil (U) takes the place of Thymine (T), but still always pairs with Adenine (A). So, if one looks at a single strand of DNA, one can reconstruct the sequence of the complementary strand from the original strand, because each base on one strand will pair with only one base on the other. Consider this single strand of DNA: DNA acts as a template because of one fact: each nitrogenous base in one strand pairs only with one other base in the complementary strand as follows: Adenine always pairs with Thymine (or Uracil in RNA) Guanine always pairs with Cytosine So, if one looks at a single strand of DNA, one can reconstruct the sequence of the complementary strand from the original strand, because each base on one strand will pair with only one base on the other. Consider this single strand of DNA: ATTGCAT Looking at the first base, we know that A always pairs with T, and that T always pairs with A for the second base, and so on. Therefore we can reconstruct the complementary strand is: TAACGTA The mRNA transcript would be: UAACGUA This fact is important in two ways. First, when a cell needs to replicate its DNA, it uses an enzyme, DNA Polymerase, to assemble complementary strands by adding nucleotides with the appropriate matching bases along the strand. The result is two identical, complete DNA molecules. Secondly, when the cell needs to build messenger RNA for protein synthesis, it uses an enzyme called RNA Polymerase to assemble the mRNA transcript by adding RNA nucleotides with the complementary matching bases from the DNA strand. The result is an mRNA transcript which will be translated into a protein whose amino acid sequence will reflect the codon sequence of the original DNA strand.
How many strands of mRNA are made during the process of transcription?
A single mRNA strand is typically produced but a single strand can make many many copies of the protein encoded on the molecule.
When transcription begins the enzyme is called?
the RNA polymerase attaches to the promoter and transcribes the gene in messenger RNA, or mRNA
