What else can I help you with?
Is it true or false that you consume the DNA of other organisms (living things) when you eat?
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.
What statements about DNA is not true?
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.
True or false nucleotide bases already attached to proteins form the copied side of the DNA ladder?
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.
True or False The nucleus contains very little of the cells 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.
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.
Is it true or false that you consume the DNA of other organisms (living things) when you eat?
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.
What statements about DNA is not true?
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.
Is it true or false that DNA is arranged into chromosomes?
true
True or false all DNA codes for protein?
true
True or false Millions of individuals have identical DNA profiles?
False. No one, except identical siblings, have the exact same DNA profiles.
The two DNA strands that form during mitosis are identical true or false?
True and false because two DNA strands can be Identical during mitosis sometimes and sometimes not.
True or false if a nucleic acid contains uracil it is DNA?
This is false a nucleic acid that contains uracil is not DNA. Uracil is a nucleobase that is found in RNA.
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.
True or False Multiple changes in DNA are required to change an abnormal cell into a cancer cell?
True.
True or false nucleotide bases already attached to proteins form the copied side of the DNA ladder?
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.
True or False Watson and Crick were the first scientists to show that genes are made of DNA?
This statement is false. Avery, MacLeod, and McCarty concluded that genes are made of DNA.
True or False The nucleus contains very little of the cells 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.
