What happens when sodium and chlorine join into a molecule?
Sodium and chlorine do not technically form molecules, but instead an ionically bonded salt. The proper term for what corresponds to a molecule in covalently bonded compounds is "formula unit" for ionically bonded compounds.
Do the rna nucleotides pair exactly as they were DNA replication?
No, RNA nucleotides in transcription pair with complementary DNA nucleotides according to the base pairing rules (A-U, G-C), as opposed to replicating DNA in which DNA nucleotides pair with complementary DNA nucleotides (A-T, G-C).
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.
What monomers are found in DNA and RNA?
In DNA, the monomers are nucleotides which consist of a phosphate group, a deoxyribose sugar, and one of the four nitrogenous bases: adenine (A), cytosine (C), guanine (G), or thymine (T). In RNA, the monomers are also nucleotides but with ribose sugar and the base uracil (U) instead of thymine.
Monomers that make up nucleic acids are known as?
Monomers that make up nucleic acids are known as nucleotides. Each nucleotide consists of a sugar, a phosphate group, and a nitrogenous base. These building blocks combine to form long chains of DNA or RNA molecules.
Does DNA consists of five different nucleotides and does RNA consists of four different nucleotides?
No, first of in total, both RNA and DNA combined have five nucleotides, DNA and RNA, both consists of three of the same nucleotides, and have one that varies between the two. Both DNA and RNA, have the nucleotides, guanine, cytosine and adenine, however DNA, has the additional nucleotide thymine and RNA instead of thymine has uracil. So, DNA's nucleotides are guanine, cytosine, adenine and thymine, while RNA's are guanine, cytosine, adenine and uracil. To specifically answer the question, no DNA consists of four different nucleotides and RNA consists of three of the same nucleotides, with one differing.
What nuclictide is replaced in RNA?
In RNA, thymine (T) is replaced by uracil (U). This means that RNA contains adenine (A), cytosine (C), guanine (G), and uracil (U) nucleotides, while DNA contains adenine (A), cytosine (C), guanine (G), and thymine (T) nucleotides.
Which enzyme synthesizes a short RNA primer at the beginning of each origin of replication?
DNA polymerase III can add nucleotides only to a chain of nucleotides that is alreadypaired with the parent strands. Hence, DNA polymerasecannot link the first nucleotides in a newly synthesizedstrand. Instead, another enzyme, an RNA polymerasecalled primase, constructs an RNA primer, a sequence ofabout 10 RNA nucleotides complementary to the parentDNA template. DNA polymerase III recognizes the primerand adds DNA nucleotides to it to construct the new DNAstrands. The RNA nucleotides in the primers are then replacedby DNA nucleotides.
What is any change in the sequence of DNA nucleotides called?
A change in the nucleotide sequence of DNA is called a mutation.Mutations take several forms:* substitution: one base is replaced by another* deletion: one or more nucleotides disappear from the sequence and the rest close up* insertion: one or more nucleotides appear between what had been adjacent nucleotides* duplication: a form of insertion in which a sequence of nucleotides is copied and now appears twice instead of once. Mutations can be caused by certain types of radiation, including ultraviolet (UV), and certain chemical compounds, which are therefore referred to as mutagenic.Mutations are particularly likely to occur at a point during replication of DNA when the two strands are separated.
Is glass ionically bonded?
No glass is not ionically bonded, Ionically bonding is due to the attraction between positively charged ions and negatively charged ions.Examples of Ionic bonds:CaCO3 - calcium carbonateFeSO3 - iron (II) sulfiteNaOH - sodium hydroxideH2S - hydrogen sulfideAgNO3 - silver nitrateGlass consists primarily of silicon dioxide, which is a covalent compound.As kinetically frozen forms of liquid, glasses are characterized by a complete lack of long-range crystalline order and are the most structurally disordered types of solid known. glasses are frozen-in non-equilibrium systems. Non-equilibrium systems cannot be described in the framework of classical thermodynamicsIn English, the bonds of glass are in small patterns, that occur numerous times. With numerous patterns it makes the bonds weak and easier to break, hence glass is brittle. Unlike other bonds.
What is the major difference between nucleotides of deoxyribonuleic acid and ribonucleic acid?
DNA: Purines: Adenine, Guanine Pyrimidines: Thymine, Cytosine RNA uses uracil instead of thymine Hope this helps
What is the number of codons that exist?
In DNA there are four different ones; Adenine, Cytosene, Guanine, and Thymine. In RNA, everything is the same except that instead of hymine, there is Uracil.
