What else can I help you with?
How did you know which bases to use when you transcribed the DNA sequence to mRNA codons?
In transcription, the mRNA strand is formed by complementary base pairing of the template DNA strand. However we should note that the nitrogenous bases in mRNA are Adenine, Guanine, Cytosine and Uracil, while those in DNA are Adenine, Guanine, Cytosine and Thymine.So the mRNA strand would be formed by matching the A in DNA with U in mRNA, T in DNA with A in mRNA, C in DNA with G in mRNA and G in DNA with C in mRNA.I hope that helps!
If a change is made in the DNA strand it is called a?
A mutation
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.
Where does a mutation occur in a nucleotide?
A mutation occurs in a nucleotide when there is a change in its structure, which can involve alterations in the nitrogenous base (adenine, thymine, cytosine, or guanine), the sugar (deoxyribose in DNA), or the phosphate group. Most commonly, mutations are associated with changes in the nitrogenous base, leading to substitutions, insertions, or deletions that can affect the genetic code. These changes can result from errors in DNA replication, environmental factors, or chemical exposure.
What type of mutation is seen below Original Strand AAGCCGAUU Mutated Strand AACCCGAUU?
The mutation seen in the original strand AAGCCGAUU to the mutated strand AACCCGAUU is a point mutation, specifically a substitution mutation. In this case, the second nucleotide 'G' has been replaced by 'C'. This change can potentially alter the resulting protein, depending on the function of the affected codon in the genetic code.

Which RNA base bonded with the Thymine?
In RNA, the nitrogenous bases change and there is no longer Thymine, instead Uracil replaces Thymine but it bonds with the same base pair ( Adenine) as it would in DNA. In other words DNA base pairs are : Adenine- Thymine, Guanine-Cytosine. RNA base pairs are : Adenine- Uracil, Guanine-Cytosine.
What is a change in the DNA?
A change in the DNA means that one of the chains were changed for example: adenine equals thymine and somehow one of them were changed into like cytosine and the other changed into Guanine.

If the fourth base adenine in the original DNA strand had been Thymine what would happen to the protein molecule?
If the fourth base adenine in the original DNA strand had been replaced with thymine, then the corresponding mRNA would have an uracil instead of an adenine. This change would lead to a different amino acid being incorporated into the protein during translation, potentially resulting in a different protein being formed depending on the specific codon affected.
What do the 4 letters A C G and T in DNA mean?
A - AdenosinT - ThyminC - CytosineG - GuanosineEach letter describes a ring/spiran (double ring) consisting out of C and N atoms with their ligands.
Why are two new strands of DNA exactly like the old strand?
The new strands have new complementary bases on one side and the other is made of the original strand. A strand of DNA has two strands that are complementary to each other in a double helix. When it gets copied one side is used as a template for the new side being added on, the bases cytosine and guanine match up and the bases adenine and thymine match up to each other. For example: If the original DNA strand has this order: 3' G-A-T-A-A-C-C 5' then the new complementary strand has: 5' C-T-A-T-T-G-G 3'
What if the C-G base pair in the DNA molecules substituted by an A-T base pair?
This really depends on where the nucleotides were in an entire DNA strand. In truth, an entire DNA pair is not substituted or mutated - the mutations occur on one DNA strand and cause problems when the matching strand is being created. So, with the example you gave, an adenine (A) could have been placed where the cytosine (C) should have been. If the same amino acid was created as a result, even with the change, there would be no effect in the end. If a similar amino acid was created with the change, the effect would be minor. A large problem may occur if the base change resulted in a completely different amino acid that would ultimately function differently. Finally, a potentially deadly result could occur if the new nucleotide signalled the production of a stop codon, or an amino acid that would stop the entire process. The DNA strands would be incomplete and could be harmful to the organism.

How does a transversion mutation result in a purine being replaced by a pyrimidine or vice versa?
A transversion mutation is a type of genetic change where a purine (adenine or guanine) is replaced by a pyrimidine (cytosine or thymine) or vice versa. This mutation occurs when a single nucleotide base in the DNA sequence is substituted with a different type of base. This change can lead to alterations in the genetic code and potentially impact the function of the gene.
Is a rolling a ball of clay into a long strand a chemical change?
No, rolling a ball of clay into a long strand is a physical change, not a chemical change. The clay's composition remains the same; only its shape is altered.
