DNA is built from just four kinds of monomers?
Yes, this is true. DNA is comprised of a backbone of deoxyribose sugars and phosphate groups. The central portion that contains the genetic code is typically made up of four monomers: adenine, guanine, cytosine, and thymine.
How many strands in a DNA molecule made of?
The point of DNA is that it is a very long, continuous chain of nitrogenous bases (cytosine, guanine, adenine and thiamine linked by a C5 sugar (deoxyribose) and phosphate groups. There are 2 complementary chains that come together to create DNA (for every T base, there'll be a T complementary and vice versa and the same is true for C and G).
What determines the nitrogen base sequence of a DNA in a new strand of DNA?
Since A pairs with T, and G pairs with C, then the sequence of bases in the strand of DNA being copied determines the sequence of bases in the newly copied strand. The bases are complementary (A gives T and G gives C when copied).
Is the calories of food energy that you consume each day are transferred to cytosine for use as an energy source for cells?
No. That's not true.
Can a single DNA strand bond with another single DNA strand?
Yes this is true :) - This happens if the two strands of DNA have organic bases complimentary to one another - E.g if one strand has the Base code - TAACGATC the other strand would have the Base code - ATTGCTAG - this is because the bases pair up as so - Adenine&& Thymine and Cytosine and Guanine - this is bcause these organic bases are complimentary due to the molecular structures allowing certain number of hydrogen bonds to form between these bases - A & T have two hyrdrogen bonds and C& G have three :D xx
Which of these bases form a true complementary pair?
adenine and guanine
What bases forms a true complementary pair?
cytosine and guanine
True or false The strands of a DNA molecule are held together by hydrogen bonding between adenine with guanine molecules and cytosine with thymine molecules?
False. Adenine pairs with thymine and guanine pairs with cytosine.
Which is true of the base pairing seen between two DNA strands?
Complementary
What is true about the nitrogen bases in DNA and RNA?
Adenine, Guanine and Cytosine are found in both RNA and DNA.DNA; A, T, G and CRNA; A, U, G and C
Can both angles in a pair of complementary angles can be obtuse true or false?
yes
True or False In DNA a base can pair with another base?
it is true to some extent. The DNA bases are Adenine(A), Thymine(T), Cytosine(C) and Guanine(G). Now the reason i say it is true is because A forms a double hydrogen bond with T only and C forms a triple hydrogen bond with G only.
Is is true that hydrogen bonds can only form between adenine and cytosine?
No. Hydrogen bonds form between water molecules, adenine and thymine, adenine and uracil, guanine and cytosine, and a myriad of other molecules.
Adenine guanine cystocine and thymine are the four nitrogen bases in DNA true or false?
There are four nitrogen bases found in DNA: adenine, guanine, cytosine, and thymine.
Which bases does Guanine always bond with to form a pair in DNA?
In a DNA molecule cytosine always pairs with guanine, the same is true for an RNA molecule.
If two angles form a linear pair then they are complementary true or false?
A linear pair are always supplementary, 180 degrees not 90.
How do the nucleotides match up in the DNA?
Purines form hydrogen bonds to pyrimidines. Adenine pairs up with Thymine (in DNA) and Uracil (in RNA) and Guanine pairs with Cytosine. A-T pairing has 2 hydrogen bonds and C-G pairing has 3 hydrogen bonds.
