Why does a double stranded molecule denature into two single stranded molecules when heated?
Wiki User

The heat breaks the hydrogen bonds that hold the nitrogenous bases together in the centre of the DNA molecule. However, the covalent bonds between the phosphate and deoxyribose sugar are not affected.

DNA molecules has how many strands?
DNA molecule is normally double stranded
Why does DNA molecules differ from the RNA molecules?
Generally the DNA molecule is double stranded to RNA's single strand. The RNA molecule uses uracil as a base while the DNA molecule uses thymine. RNA has catabolic properties that allow it to act in things such a ribosomes and tRNA. DNA is just a carrier of the genetic information.
Are Single stranded DNA molecules are said to be antiparallel when they lined up next to each other but oriented in opposite directions?
Yes. Technically they need to be two individual strands of a double-stranded molecule and not single-stranded molecules in order to be called antiparallel.
Is trna double stranded or single stranded?
tRNA, or transfer RNA, is a single stranded molecule. The only double stranded RNA is dsRNA, or double stranded RNA. They are typically found in viruses.
Which of these sentences states why the DNA molecule differs from the RNA Molecule?

How are 2 double stranded DNA molecules created?
Two double stranded DNA molecules are created by the process of DNA replication.
The double-stranded structure of a DNA molecule is referred to as the?
The double helix.
What kind of molecules are transcripts?
DNA Molecules
Is trna double stranded or single stranded?
tRNA, or transfer RNA, is a single stranded molecule. The only double stranded RNA is dsRNA, or double stranded RNA. They are typically found in viruses.
What is the main component of most bacterial genomes?
double-stranded circular DNA molecules that is associated with a small amount of protein
What is a single helix molecule?
A DNA molecule has the shape of a double-stranded helix.

What bacteria is circular double-stranded DNA molecule that is capable of independent replication?
plasmid
