What else can I help you with?
Is there always going to be an equal number of guanine and cytosine nucleotides in a molecules Why?
That depends on what the molecule is. In DNA, there will be the same concentration of each, because they are paired, and DNA is a double stranded molecule. Thus, for each cytosine, there will be a guanine, and vice versa. In RNA however, it is single stranded, so the two do not have to match exactly.
Is there always going to be an equal nucleotide in a molecule?
In a double-stranded DNA molecule, there are always equal amounts of adenine (A) and thymine (T), as well as equal amounts of cytosine (C) and guanine (G), due to base pairing rules. However, in single-stranded DNA or RNA, there is no requirement for equal nucleotide composition, and the proportions of each nucleotide can vary significantly. Thus, while complementary strands of DNA exhibit this equality, it does not universally apply to all nucleotide sequences.
By convention the sequence of bases in a nucleic acid is always written in which direction?
The sequence of bases in a nucleic acid is always written in the 5' to 3' direction.
What is the base unit of a nucleic acid?
The nitrogenous base units of a nucleic acid are Adenine, Cytosine, Guanine, and Thymine. (in Dna) in RNA Thymine is replaced with Uracil. These base pair are often abreviated to A,C,T,G, and U. Adenine will always pair with Thymine. Cytosine will always pair with guanine.
Can a molecule be octahedral?
No. A molecule of octahedral shape is always non-polar
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.
Is RNA always single stranded?
No, RNA is not always single stranded. It can exist as single stranded or double stranded depending on its function and structure.

In a DNA molecule which nitrogen bases always bond with each other?
Adenine and Thymine together and cytosine and guanine together.
In a DNA molecule with nitrogen bases always bond with each other?
Adenine and Thymine together and cytosine and guanine together.
Are there always going to be an equal number of adenine and thymine nucleotides in a molecule why?
Yes, there will always be an equal number of adenine (A) and thymine (T) nucleotides in a DNA molecule. This is because adenine always pairs with thymine through hydrogen bonding in a double-stranded DNA molecule, following Chargaff's rule.

Can mRNA be a double strand?
In a strict sense no. mRNA always consists of a single RNA strand. In another sense, yes. Nuclei acids are inherently unstable in a single stranded state - the nitrogenous bases will spontaneously basepair with any nucleotides they encounter. As a result, most RNAs will spontaneously fold back on themselves, the single RNA strand basepairing with other regions of itself. That said, because the sequence will never be perfectly complementary, it's unlikely that much of the mRNA will be double stranded, but it will probably have a few segments with a double stranded character.
What is the primary function of DNA and where is DNA located and is DNA single stranded or double stranded?
Function: The fundemental unit of life. codes for everything. The building blocks of everything else (DNA->RNA->amino acids->proteins) Location: Nucleus Almost always double stranded (RNA is always single stranded)
By convention the sequence of bases in a nucleic acid is always written in which direction?
The sequence of bases in a nucleic acid is always written in the 5' to 3' direction.
What is double stranded RNA or DNA?
Double-stranded RNA or DNA refers to a molecule that is composed of two strands of nucleotides, where the nucleotide bases are paired together (A with T or U, and G with C) through hydrogen bonds. These molecules are commonly found in organisms as genetic material. In the case of RNA, it can also play a role in gene regulation and defense mechanisms against viral infections.
Do uracil always pair with cytosine in the RNA molecule?
Cytosine is always coupled with Guanine. (I like to remember that the round letters stick together).In DNA, Thymine is coupled with Adenine, but in RNA, Thymine is replaced by Uracil.Therefore, in RNA, U and A go together, always.
