What does nucloetide may contain?
A nucleotide may contain three components: a nitrogenous base (adenine, guanine, cytosine, thymine, or uracil), a pentose sugar (such as ribose or deoxyribose), and a phosphate group. These components are the building blocks of nucleic acids like DNA and RNA.
What is the part of the nucleotide that differs among the other different nucleotides?
All nucleotides are similar except for the nitrogen bases, which may either be adenine, cytosine, guanine, thymine, or uracil..
A nucleotide may contain?
thymine and deoxyribose
What might happen if there was an extra nitrogenous base deleted from the mRNA code?
If an extra nitrogenous base is deleted from the mRNA code, it can disrupt the reading frame, leading to a frameshift mutation. This can change the amino acid sequence of the resulting protein, potentially altering its structure and function. The protein may not be properly synthesized or may not function correctly, affecting cellular processes.
Why does uracil replace thymine in RNA?
Funnily enough, it is probably the other way round! Scientists believe, for various reasons, that RNA came first, and that there was an "RNA world" before DNA evolved. If this idea is correct, uracil was a component of nucleic acids before thymine. When DNA evolved, thymine may have proved a preferable material for storing genetic information because of its much greater stability; RNA breaks down relatively quickly, but DNA is stabilized by its double-stranded form. RNA is easily hydrolised than DNA. It is interesting to note that in our own bodies we can synthesize RNA from simpler compounds, but to make DNA we first build RNA nucleotides, then convert them. We remove one oxygen atom from the ribose component of the nucleotide, to form deoxyribose. Then, if the base is uracil, we add a methyl group to it to form thymine. But this leaves the question: what advantage does thymine have over uracil in DNA? One suggestion is this: cytosine (C) occasionally converts into uracil (U) by deamination. If this U is not removed, at the next replication it will act as a template for an adenine (A) on the new strand, and there will have been a mutation from G to A. Having thymine (T) as the regular base in DNA makes it easy for a cell to spot a deamination, because U should not be there at all. The cell then removes the U with a DNA repair enzyme (e.g. uracil glycosylase).
The components of a nucleoside are?
The components of a nucleoside are: A pentose sugar(generally ribose or deoxyribose), and a nitrogenous base which may be Adenine/Guanine/Thymine/Cytosine/Uracil. It becomes a nucleotide on addition of a phosphate group.
What does nucloetide may contain?
A nucleotide may contain three components: a nitrogenous base (adenine, guanine, cytosine, thymine, or uracil), a pentose sugar (such as ribose or deoxyribose), and a phosphate group. These components are the building blocks of nucleic acids like DNA and RNA.
What base is missing on RNA and what other base replaces it?
No nitrogen base is missing. You may be referring to the fact that DNA contains the nitrogen base thymine, while RNA contains the nitrogen base uracil. They both contain adenine, cytosine, and guanine.
What is notrogen basis?
It seems like there may be a typo in your question. Did you mean "nitrogen basis" or "nitrogenous base" perhaps? If so, nitrogenous bases are molecules found in the structure of DNA and RNA, specifically adenine, guanine, cytosine, and thymine (or uracil in RNA). These bases pair up in a specific way to encode genetic information.
What is the one part of nucleotide that differs among the other different nucleotide?
All nucleotides are similar except for the nitrogen bases, which may either be adenine, cytosine, guanine, thymine, or uracil..
What elements form a nitrogen base?
A nitrogen base is formed from nitrogen atoms and other elements such as carbon, hydrogen, and oxygen. These elements are arranged into specific structures like adenine, cytosine, guanine, thymine, and uracil, which are key components of DNA and RNA molecules.
Why does DNA have thymine when RNA has uracil?
Cytosine bases may spontaneously change into uracil bases. DNA has an enzyme asssociated with it that corrects this fault. If DNA contained uracil as a base, the repair enzyme would have no way of distinguishing between uracils normally present in the DNA code and uracils that had formed from cytosine. Therefore thymine is present instead of uracil.

What is the subunit structure of nuclear acids?
May I ask you what is a subunit of a nucleic acid or are you implying that what is the composition of of that simple strand. If so then it is comprised of nitrogenous base, a phosphate, and also a sugar. Here is a simple example ; dna, it is comprised of guanine, thymine, cytosine, and adenine. Its sugar is deoxyribose, thus hence the name deoxyribonucleic acid .
Nitrogenous wastes is it creatinine or fatty acid or lipid or carbon dioxide or sugar?
Nitrogenous wastes are waste substances which contain nitrogen. Generally these are produced in the liver by the breakdown of unwanted amino acids. Most of the waste (in mammals) is in the form of urea, but smaller amounts of other substances, such as creatinine, are also produced. Carbon dioxide only contains carbon and oxygen. Sugar and fatty acids only contain carbon, hydrogen and oxygen. Some lipids (phospholipids) may contain small amounts of nitrogen.
A virus may contain ethier DNA or RNA To identify which nucleic acicd is present a biochemist could chemically analyze the virus for the presence of which nitrogen base?
The "NA" in DNA and RNA stands for nucleic acid, so in this question, you are trying to find which nitrogen base ethier only DNA or only RNA has. DNA has thymine, but RNA has uracil. Therefore, the biochemist could chemically analyze the virus for the presence of uracil.
