DNA consists of how many chains?
A DNA molecule has two chains of nucleotides. Each chain is usually referred to as a DNA strand. RNA has only one strand.
How does a single DNA molecule produce two identical molecules?
Two single chains bond together. The bonded chains twist together to form a double helix.
DNA is an example of what?
DNA consists of two long polymers of simple units called nucleotides, with backbones made of sugars and phosphate.
What scientist in 1952 discovered that DNA is actually two chains of molecules in spiral form?
Rosalind Franklin
What causes the base pairs in DNA to break apart?
The base pairs in DNA are broken apart during replication. Specific enzymes such as DNA polymerase break the nucleic acids apart forming two chains of DNA.
DNA exists as two long chains of molecules twisted around each other in a structure called a?
double helix ramon c.
What are the long chains that DNA make up?
DNA is made of two strands (chains) of DNA nucleotides that are twisted, forming a double helix, often compared to a twisted ladder. The two strands are held together by hydrogen bonds between the nitrogen bases.
Is DNA a single straneded?
Of course not,DNA consist of two helical chains
What are Sugar in a DNA?
DNA two backbone chains of phosphates and deoxyribose sugars.
DNA consists of how many chains?
A DNA molecule has two chains of nucleotides. Each chain is usually referred to as a DNA strand. RNA has only one strand.
What carry DNA information for traits?
Pattern of basics between two helical chains of a DNA
What direction must two chains of DNA run?
The two chains of a piece of DNA must run in opposite directions (anti-parallel). One chain runs 5' to 3', and the other runs 3' to 5'.
At the end of DNA replication two new strands of DNA have been produced giving a total of?
Two new DNA chains are formed at the end of DNA replication, both identical in sequence to the template (or parent) chain. These chains are composed of 2 complimentary strands. It is important to note that of the newly formed DNA chains, one strand is the same as the template strand and the other one is a newly synthesized one.
How does a single DNA molecule produce two identical molecules?
Two single chains bond together. The bonded chains twist together to form a double helix.
DNA is an example of what?
DNA consists of two long polymers of simple units called nucleotides, with backbones made of sugars and phosphate.
How many polynucleotide chains are in each DNA molecule?
hundreds and thousands =) : im looking at my book right now because i also needed this answer.
DNA is built of billions of subunits called?
Nucleic acids consist of either one or two long chains of repeating units called nucleotides, which consist of a nitrogen base (a purine or pyrimidine) attached to a sugar phosphate.
