What is the genetic molecule of a virus?
The genetic molecule of a virus is either DNA or RNA, but not both. Viruses can have single-stranded or double-stranded DNA or RNA.
What four bases of nucleic acids always bond together in the double stranded molecule?
Adenine bonds with thymine, and cytosine bonds with guanine in a double stranded nucleic acid molecule. This pairing is referred to as complementary base pairing in DNA.
What are the two strands of a double stranded chromosome called?
The two strands of a double-stranded chromosome are called chromatids. Each chromatid contains a single DNA molecule that is duplicated and bound to its sister chromatid at the centromere.
How are DNA and rna molecule oriented and structed in the nitrogenous bases?
DNA is double helix and rna is single stranded and twisted
What molecule contains the cell's genome?
DNA (deoxyribonucleic acid) contains the cell's genome. DNA is a double-stranded molecule that stores the genetic information of an organism.
Is trna double stranded or single stranded?
tRNA is single stranded. It forms a cloverleaf-like structure with base pairing within the molecule itself, but it is not double stranded like DNA.
The double-stranded structure of a DNA molecule is referred to as the?
The double helix.
A characteristic of a DNA molecule that is not a characteristic of a protein molecule is that the DNA molecule?
can store genetic information and pass it on to the next generation through replication, while a protein molecule cannot replicate itself in the same way. Additionally, DNA has a double-stranded helical structure, while proteins have a primary, secondary, tertiary, and quaternary structure.
Which molecule is always single stranded?
RNA is always single stranded. DNA, on the other hand, can exist as either single-stranded or double-stranded.
What is the genetic molecule of a virus?
The genetic molecule of a virus is either DNA or RNA, but not both. Viruses can have single-stranded or double-stranded DNA or RNA.
Which of these sentences states why the DNA molecule differs from the RNA Molecule?
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.
A double-stranded DNA molecule contains 30 percent guanine What is the percent cytosine in this molecule Where is the promoter region?
30 percent
Why does a double stranded molecule denature into two single stranded molecules when heated?
Heating disrupts the hydrogen bonds holding the two strands together in a double-stranded molecule, causing them to separate into two single-stranded molecules. This process is known as denaturation, where the structure of the DNA or RNA molecule is altered due to the breakage of hydrogen bonds, leading to the unwinding of the double helix.
Which two bases are present in equal amounts in a double-stranded DNA molecule?
The two bases that are present in equal amounts in a double stranded DNA molecule are cytosine and guanine. Cytosine pairs with guanine in A DNA molecule.
The spiral staircase structure characteristic of the DNA molecule?
Double helix
What four bases of nucleic acids always bond together in the double stranded molecule?
Adenine bonds with thymine, and cytosine bonds with guanine in a double stranded nucleic acid molecule. This pairing is referred to as complementary base pairing in DNA.
The double-stranded DNA molecule is held together by four chemical components called?
The double-stranded DNA molecule is held together by four chemical components called nucleotides. These nucleotides are adenine, thymine, guanine, and cytosine, and they form base pairs with each other to create the structure of DNA.
