What three basic molecules are nucleotides composed of?
A phosphate group, a sugar and a nitrogenous base
What does a group of three nucleotides code for?
DNA nucleotides 'code' for RNA copies of the DNA strand, but the true 'coding' of nucleotides happen in the ribosome where amino acids are matched to the RNA nucleotides. Nucleotides in DNA are only are present to store genetic data. When a particular gene needs to be used or a protein needs to be made, a RNA copy of the DNA will be made, using the slightly different RNA nucleotides (adenine, uracil, cytosine and guanine). This copy then leaves the nucleus and travels to the ribosome, where the RNA nucleotides are used to assemble amino acids into proteins. Each amino acid matches up to a three-nucleotide sequence.
What enzyme joins the nucleotides of a DNA strand together?
That depends on the process. During DNA replication, The nucleotides of the lagging strand (Okazaki fragments) are connected by DNA ligase. In transcription, the nucleotides of RNA are connected by RNA polymerase II.DNA Polymerse
Subunits of nucleic acids?
The monomers of nucleic acid polymers are the nucleotides. Each is composed of a sugar-phosphate backbone and one of four bases as a side group. In RNA the sugar is ribose, in DNA the sugar is deoxyribose.
How do nucleotides in the RNA molecule code for various amino acids How many nucleotides code for one amino acid?
Each nucleotide is made up of an organic base, a pentose sugar and a phosphate. Nucleotides can be arranged in various different orders and that order dictates which amino acid it codes for, three amino acids code for one nucleotide. Is this enough detail?
Which base is found on DNA nucleotides but not rna nucleotides?
Thymine is found on DNA nucleotides but not on RNA nucleotides. In RNA, thymine is replaced by uracil.
Which base is only found in RNA nucleotides?
Uracil is only found in RNA nucleotides. In DNA uracil is replaced by thymine.
What connects Rna nucleotides to dNA during transcription?
During transcription, RNA polymerase catalyzes the synthesis of an RNA molecule by base-pairing complementary RNA nucleotides with the DNA template strand. This complementary base pairing allows the RNA nucleotides to be connected to the DNA template, forming a growing strand of RNA that is identical in sequence to the non-template DNA strand.
What is an RNA nucleotide?
An RNA nucleotide is the building block of RNA, consisting of a nitrogenous base (adenine, guanine, cytosine, or uracil), a ribose sugar, and a phosphate group. These nucleotides are linked together to form RNA strands during transcription.
Which base is found in DNA nucleotides but not RNA molecules?
DNA contains thymine, but RNA has uracil in its place.
Is strand of nucleotides in the RNA or DNA?
A strand of nucleotides can be found in both RNA and DNA. RNA is typically single-stranded, while DNA is double-stranded. Both molecules consist of nucleotides that contain a sugar, a phosphate group, and a nitrogenous base.
Is RNA made up of nucleotides?
Yes, RNA is composed of nucleotides. Each RNA nucleotide consists of a sugar molecule (ribose), a phosphate group, and one of four nitrogenous bases (adenine, cytosine, guanine, or uracil). These nucleotides are connected together through phosphodiester bonds to form an RNA strand.
How many nucleotides make up RNA and what are their?
Four different ribonucleotides are present in RNA. They are Uracil, Adenine, Guanine and Cytosine.
What is the name of sugar present in tRNA nucleotides?
The sugar present in RNA (including tRNA AND mRNA) is Ribose sugar.
What organic substance is made up of nucleotides?
DNA and RNA are organic substances that are composed of nucleotides. A nucleotide contains a sugar, a phosphate group, and an organic base.
An organic base that contains nitrogen a subunit of a nucleotide in DNA and RNA is?
Adenine is an organic base that contains nitrogen and is a subunit of nucleotides in both DNA and RNA.
What three basic molecules are nucleotides composed of?
A phosphate group, a sugar and a nitrogenous base
