What happens to one strand of DNA when there is a change in a base on a the other strand?
This is called a "mutation." What ends up happening depends on where the base that changed was located.
If the changed base is on the side of the DNA strand that is not used in making mRNA, there will be no difference in the final protein made whatsoever.
If the mutation occurs in a part of the DNA that is not coded to make a protein (so called "junk" DNA), there will also be no change in the final protein, because there won't be a protein made.
Even if the mutation occurs in a segment of DNA that eventually makes a protein, if the replacement base causes the mRNA to code for an amino acid that is similar to the original base, there will be little change. There is more to it, but that will probably suffice.

What happen to the bottom strand of DNA when there is a change in a base on the top strand?
Nothing happens immediately. But when the two strands separate and construct new strands. The bottom strand will replicate the old top strand. The top strand will create a changed bottom strand. The two new cells after cell division will have different genetic codes. Most changes stop at this point because the "NEW" code won't be viable. Now if the change on the top immediately changes the bottom. Then the cell itself stops functioning unless it is a viable change.

What happens if you change the 9th base from adenine to cytosine in the DNA Strand?
This would be a point mutation, which may be harmless, or could be lethal, depending on the protein in which it occurred.

Why can you predict the base sequence of one strand in a molecule of DNA if you know the sequence of the others strand?
in DNA, each base pairs up with only one other base
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.
What happens to one strabd of DNA when there a base on the other strand?
When there is a base on one strand of DNA, it pairs with a complementary base on the opposite strand through hydrogen bonding. For example, adenine (A) pairs with thymine (T), and guanine (G) pairs with cytosine (C). This specific base pairing is essential for maintaining the DNA double helix structure and ensures accurate replication and transcription of genetic information. If a base is mismatched, it can lead to mutations or errors during DNA replication.
What is the sequence of the base os agctcag on the opposite strand?
A TG CAGATTCTCTAAG
What is the relationship of the two DNA strands to each other?
The two strands in a DNA molecule (the polynucleotides) are complementary to each other. This means that the base sequence in one strand determines the base sequence in the other strand. This happens because of specific base pairing. An adenine in one strand always pairs with a thymine in the other strand, and a cytosine in one strand always pairs with a guanine in the other strand. So if you know the base sequence in one strand of the DNA yoiu can work out the sequence in the complementary strand. See: http://www.phschool.com/science/biology_place/biocoach/dnarep/basepair.htmlDNA strands run anti-parallel from one another, and have a double helix structure. The strands are held together by hydrogen bonds between base pairs that are weak individually, but collectively strong.
What letters would form the other strand of the helix?
In DNA, the other strand of the helix would have complementary base pairs to the original strand. Adenine pairs with thymine, and cytosine pairs with guanine. So, if one strand has the sequence ATTGC, the complementary strand would be TAACG.
What is the base sequence on the other strand?
To determine the base sequence on the complementary DNA strand, you need to know the base sequence of one strand. DNA is composed of four bases: adenine (A), thymine (T), cytosine (C), and guanine (G). The complementary base pairing rules state that A pairs with T and C pairs with G. For example, if the given strand is 5'-ATCG-3', the complementary strand would be 3'-TAGC-5'.
