Both DNA and RNA are nucleic acids composed of nucleotides with a sugar-phosphate backbone. They both contain adenine, cytosine, and guanine as bases, but RNA contains uracil instead of thymine. Both molecules are essential for storing and transferring genetic information in cells.

True or false After replication the nucleotide sequences in both DNA molecules are identical to each other and to the original DNA molecule?
True. After replication, the nucleotide sequences in both DNA molecules are indeed identical to each other and to the original DNA molecule. This ensures that genetic information is accurately duplicated during cell division.
Does adenine nuleotide occur in DNA but not in RNA molecules?
Adenine is a nucleotide base that occurs in both DNA and RNA molecules. However, the difference lies in the sugar component: in DNA, the sugar is deoxyribose, while in RNA, the sugar is ribose.
True or false the DNA from your nails is the same DNA as your hair?
True. Both nails and hair are made of a protein called keratin, and the DNA within the cells that produce these structures is the same. Thus, the DNA from your nails is the same as the DNA from your hair.
Scientists use gel electrophoresis to cut dna at a specific nucleotide True or false?
It is true that Scientists use gel electrophoresis to cut DNA molecules at a specific sequence of nucleotides.
How does DNA molecules differ from daughter DNA molecules?
DNA molecules contain genetic information in a double-stranded helical structure, while daughter DNA molecules are formed during DNA replication and consist of two identical copies of the original DNA molecule. Daughter DNA molecules are produced through a semi-conservative process where one strand of the original DNA molecule is conserved in each daughter molecule.
True or false After replication the nucleotide sequences in both DNA molecules are identical to each other and to the original DNA molecule?
True. After replication, the nucleotide sequences in both DNA molecules are indeed identical to each other and to the original DNA molecule. This ensures that genetic information is accurately duplicated during cell division.
Are DNA molecules transported out through the pores?
no this is not true
Does adenine nuleotide occur in DNA but not in RNA molecules?
Adenine is a nucleotide base that occurs in both DNA and RNA molecules. However, the difference lies in the sugar component: in DNA, the sugar is deoxyribose, while in RNA, the sugar is ribose.
Is the order of base pairsfrom top to bottomdifferent or the same for each new DNA molecules?
Assuming that no errors occurred during DNA replication, both copies of the new DNA molecules should be identical.
True or false the DNA from your nails is the same DNA as your hair?
True. Both nails and hair are made of a protein called keratin, and the DNA within the cells that produce these structures is the same. Thus, the DNA from your nails is the same as the DNA from your hair.
Scientists use gel electrophoresis to cut dna at a specific nucleotide True or false?
It is true that Scientists use gel electrophoresis to cut DNA molecules at a specific sequence of nucleotides.
When one DNA molecule is replicated the result is two DNA molecules. What is true of the second DNA molecule?
The second DNA is an exact duplicate of the first. If not the second will not work correctly. We call this a mutation.
True or false Only DNA molecules contain the nitrogen base called uracil?
False. Uracil is a nitrogen base found in RNA molecules, not DNA. In DNA, thymine is the equivalent nitrogen base to uracil.
What is an example of a sugar phosphate backbone?
DNA and RNA molecules have a sugar phosphate backbone. In DNA, the sugar is deoxyribose, while in RNA it is ribose. The phosphate groups link the sugar molecules together forming a linear chain.
Is a phosphate DNA or RNA?
A phosphate group is found in both DNA and RNA. It is an essential component of the nucleotides that make up the backbone of the DNA and RNA molecules.
DNA replications begins in areas of DNA molecules called what?
DNA replication begins in areas of DNA molecules are called origins of replication.
The DNA molecule has both strong bonds and weak bonds which hold the molecule together. is this true or false?
True
