False. There are only four nucleotide bases, the different arrangements of these bases create a unique genetic code that is specific to each different organism.
True. When you eat, you consume the DNA of other organisms, as DNA is present in the cells of all living things that you consume as food.
One untrue statement about DNA is that it is the only genetic material in living organisms. Another untrue statement is that all DNA is organized in the same way in all organisms. Additionally, it is false to say that DNA is a protein.
False. Nucleotide bases attached to proteins do not form the copied side of the DNA ladder. The new DNA strand is actually synthesized in a complementary fashion to the template strand during DNA replication.
No - quite the opposite. The nucleus is where almost all of the DNA in a cell is found. Small amounts are also found in some organelles, such as mitochondria - and this is the only form of DNA found outside the nucleus.
False. Uracil is a nitrogen base found in RNA molecules, not DNA. In DNA, thymine is the equivalent nitrogen base to uracil.
True. When you eat, you consume the DNA of other organisms, as DNA is present in the cells of all living things that you consume as food.

False. No one, except identical siblings, have the exact same DNA profiles.
True and false because two DNA strands can be Identical during mitosis sometimes and sometimes not.
This is false a nucleic acid that contains uracil is not DNA. Uracil is a nucleobase that is found in RNA.
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.
True.
False. Nucleotide bases attached to proteins do not form the copied side of the DNA ladder. The new DNA strand is actually synthesized in a complementary fashion to the template strand during DNA replication.
This statement is false. Avery, MacLeod, and McCarty concluded that genes are made of DNA.
No - quite the opposite. The nucleus is where almost all of the DNA in a cell is found. Small amounts are also found in some organelles, such as mitochondria - and this is the only form of DNA found outside the nucleus.
