What is the 2nd stand matching DNA?
The 2nd strand matching DNA refers to the strand that can pair with the original DNA sequence through complementary base pairing. In DNA replication, this matching strand is synthesized by DNA polymerase according to the sequence on the original template strand.
Is a newly synthesized strand half of the original stand with newly formed complimentary half?
Yes, during DNA replication, a newly synthesized strand is formed by pairing complementary nucleotides with the original strand. This results in one strand being the original and the other being newly synthesized, forming a complementary pair.
What do the template strands of DNA always begin with?
DNA is made of of two complimentary strands, the coding strand and the template strand. When DNA is transcribed (made into messenger RNA which can be converted by ribosomes into proteins) the DNA splits open and free nucleotide bases bind to the template strand. DNA is made of T/C/G/A and RNA is made of U/C/G/A nucleotide bases. G and C bind (they are said to be 'complimentary') A and T bind and in RNA U and A bind (so U replaces T.) The newly formed RNA strand (made on the template stand of DNA) is 'complimentary' to the template but the same as the coding strand of DNA. Hence the template is used to produce RNA which is a copy of the coding strand. Either strand of DNA can act as the template/coding strand. Hope that is a little bit helpful!
What is the new mRNA stand produced by this mutated gene?
The specific sequence of the new mRNA strand produced by a mutated gene will depend on the nature of the mutation. Mutations can cause changes in the coding region of the gene, leading to alterations in the mRNA sequence and potentially affecting the resulting protein or gene function. Further analysis and sequencing of the mutated gene would be required to determine the exact mRNA sequence.
A nucleotide is about to be added to a growing strand of DNA. What factor determines which type of nucleotide will be added?
The sequence of nucleotides in the template DNA strand determines which complementary nucleotide will be added to the growing strand. A-T and G-C base pairing rules govern the selection of the nucleotide to be added during DNA replication.
What is the genetic code on the complimentary stand?
The genetic code on the complementary strand refers to the sequence of nucleotides that pairs with a corresponding sequence on the original DNA strand. In DNA, adenine (A) pairs with thymine (T), and cytosine (C) pairs with guanine (G). Therefore, if the original strand has a sequence like ACGT, the complementary strand would have the sequence TGCA. This complementary base pairing is crucial for DNA replication and transcription processes.
Why can you predict the base sequence of one stand in a molecule of DNA if you know the sequence of the other stand?
DNA is made up four nucleotide bases,a pentose sugar and a phosphate. The four nucleotides are adenine, guanine, cytosine and thymine. Due to the nature of these molecules they fall into two groups called purines ( adenine an guanine) and pyrimidines ( cytosine and thymine). The bases have complimentary base pairing causing the double helix shape of DNA. adenine always bonds with thymjine and guanine with cytosine. So you can predict what the base sequence of one strand the other strand will be the opposite base pairing, for example if you know that a strand is AGAACTG the complimentary strand is TCTTGAC.

Why can you predict the base sequence of one strand in amloecule of DNA if you know the sequence of the other stand?
You can predict the base sequence of one strand of DNA if you know the sequence of the other strand because DNA strands are complementary. Adenine (A) pairs with thymine (T), and cytosine (C) pairs with guanine (G). This complementary base pairing allows the sequence of one strand to dictate the sequence of the other, enabling accurate predictions of the base sequence.

The 2nd strand matching DNA refers to the strand that can pair with the original DNA sequence through complementary base pairing. In DNA replication, this matching strand is synthesized by DNA polymerase according to the sequence on the original template strand.
If the sequence of nitrogenous bases is one standard of DNA is gta-gca the sequence of bases on its complementary DNA stand would be?
The complementary DNA strand is formed by pairing adenine (A) with thymine (T) and cytosine (C) with guanine (G). Therefore, if one strand has the sequence gta-gca, the complementary strand would have the sequence cat-cgt.
Is a newly synthesized strand half of the original stand with newly formed complimentary half?
Yes, during DNA replication, a newly synthesized strand is formed by pairing complementary nucleotides with the original strand. This results in one strand being the original and the other being newly synthesized, forming a complementary pair.
Which stand of mrna would be made during transcription using the DNA straind?
During transcription, the mRNA strand is synthesized using the template DNA strand, which runs in the 3' to 5' direction. The mRNA is created in the 5' to 3' direction, meaning that RNA polymerase adds complementary RNA nucleotides to the growing strand. For example, if the DNA template strand has a sequence of 3'-ATCGTA-5', the resulting mRNA would have the sequence 5'-UAGCAU-3'.
What is the complementary strand of DNA?
The complementary strand of DNA is a strand that matches the sequence of the original DNA strand through base pairing rules. Adenine pairs with thymine (A-T) and cytosine pairs with guanine (C-G). This results in two DNA strands with complementary sequences that can be used for replication and transcription.
What do the template strands of DNA always begin with?

When DNA is transcribed (made into messenger RNA which can be converted by ribosomes into proteins) the DNA splits open and free nucleotide bases bind to the template strand.

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.
What is a stand of DNA that does not make an exact copy of itself?
It is a mutated strand sinc e mutated strand isn't an exact copy of the original.
