What forms a base pair with thymine?
Adenine pairs with thymine.
What base is not present in the nucleotides of RNA?
RNA has the base uracil rather than thymine that is present in DNA, so the answer to you question is.. thymine.
RNA is to U as DNA is to?
In RNA, the nitrogenous base of U (Uracil) is in place of T (Thymine) in DNA.
What are the names of the four nitrogen bases that make up part of DNA?
A (adenine), T (thymine), C (cytosine), and G (guanine). A, T, G, C. But there are five. U is the other one. It's found in RNA, not DNA, and is probably not one of the four you're after.
What is the nitrogenous base t?
thymine
Which molecule is active during the last step during DNA replication?
DNA ligase. Apex
What is the purpose of DNA polymerase?
DNA polymerase is an enzyme that helps in DNA replication. It helps to synthesize and catalyze the bonds between the nucleic acids in DNA (adenine, cytosine, guanine, thymine).
What is the explanation for the Role of RNA polymerase?
Basically, RNA polymerase's role is very similar to that of DNA polymerase. RNA polymerase is an enzyme that is used during transcription in the nucleus. Similar to DNA polymerase, RNA polymerase codes for the complementary nucleotides to a DNA strand. Instead of thymine though, uracil codes with adenine. This coded mRNA strand then travels from the nucleus to the ribsome where translation occurs - the result is protein made from an amino acid chain. To answer your main question - RNA polyermase adds the complementary nucleotides to the DNA strand using uracil instead of thymine. hope that helps :)
Which nitrogenous bases are the pyrimidines and which are the purines?
Cytosine, thymine and uracil are the pyrimidines in animal usage.
What is DNA polymerases?
DNA polymerase is the chief enzyme of DNA replication. It helps to synthesize and catalyze the bonds between the nucleic acids in DNA (adenine, cytosine, guanine, thymine).DNA polymerase is an enzyme that are involved in DNA synthesis
To repair a thymine dimmer by nucleotide excision repair in which order do the necessary enzymes act?
Endonuclease, DNA polymerase I, DNA ligase. I hope this helps
What is initiation in transcription?
So in Transcription there are three main steps: Initiation, elongation and termination. The one I'm focusing on is Initiation. In eukaryote, proteins called transcription factors mediate the initiation of transcription by RNA Polymerse II. A eukaryotic promoter commonly includes a TATA box, a nucleotide sequence containing "Thymine-Adenine-thymine-adenine", about 25 nucleotides upstream from the transcriptional start point.
Different DNA and RNA?
RNA is single stranded, uses uracil instead of thymine, and is less stableRNA has a ribosesugar backbone. DNA had a deoxyribosesugar backbone. RNA usesDNA is double stranded...ittransfers parental characters into offspring and contains thymine base
What nitrogen base is replaced with uracil in RNA?
Thymine
Differences between DNA polymerase and RNA polymerase?
A polymerase is an enzyme that catalyzes the conversion of free nucleotides into a single strand. DNA polymerase differs from RNA polymerase in two major respects: * Like all enzymes, DNA polymerase is substrate-specific. DNA polymerase cannot extend a single strand of DNA; it needs at least a short segment of double-stranded DNA at the outset. * As its name implies, DNA polymerase incorporates deoxyribonucleotides into the new strand. RNA polymerase incorporates ribonucleotides. These differences mean that DNA polymerase is active when new DNA strands are formed, as in DNA replication, and RNA polymerase is active when new RNA is formed, as in transcription. Before DNA replication can begin, the two strands must uncoil, so that each can form a template for free nucleotides to attach to. But DNA polymerase cannot get started with a single strand! In vivo(in the cell) RNA polymerase, which is active in the presence of single-stranded DNA, catalyzes the incorporation of a handful of nucleotides into a new strand. The short length of double-stranded nucleic acid that is produced enables DNA polymerase to swing into action. This still leaves a potential difficulty: the nucleotides incorporated in the presence of RNA polymerase are the wrong sort (ribonucleotides). They are subsequently replaced by DNA polymerase. In vitro (during PCR, the polymerase chain reaction) a primer, specially synthesized in a laboratory, attaches to a specific segment of single-stranded DNA, and the DNA polymerase takes over from there. The primer consists of a short length of single-stranded DNA that uniquely complements a specific DNA segment that is targeted for amplification, for example for forensic analysis.In practice, there are several different DNA polymerases and RNA polymerases in an organism.
What base is found DNA but not in RNA?
Thymine
What is a promoter in DNA?
A promoter is a sequence of nitrogenous bases in DNA that signals the enzyme complex "DNA-polymerase" to begin unwinding the gene to transcribe it. A promoter is usually referred to as a "TATA (thymine, adenine, thymine, adenine) box" or a "CAAT (cytosine, adenine, adenine, thymine) box". As DNA polymerase makes its way down a section of DNA and comes across TATA box, or a CAAT box, that is the signal to begin transcription.
