What DNA sequence complements the messenger RNA sequence?
What base sequence in the original DNA would be transcribed into an mRNA codon that joins with the tRNA Anticodon shown below?
Q. What base sequence in the original DNA would be transcribed into an mRNA codon that joins with the tRNA anticodon shown below? The base sequence of the tRNA anticodon is adenine, guanine, and uracil (AGU).
What tRNA Anticodon is complementary to the mRNA codon GUA?
|Amino Acid||Coding DNA Strand Base Triplets Not Transcribed||Transfer RNA Anticodons Complementary To M-RNA Codons|
|glycine||GGT, GGC, GGA, GGG||CCA, CCG, CCU, CCC|
|histidine||CAT, CAC||GUA, GUG|
|isoleucine||ATT, ATC, ATA||UAA, UAG, UAU|
|leucine||TTA, TTG, CTT, CTC CTA, CTG||AAU, AAC, GAA, GAG GAU, GAC|
Which statement best describes the role of mRNA in protein synthesis quizlet?
Which best describes the role of mRNA in protein synthesis? mRNA brings the code of DNA to the ribosome where it is used to construct a protein. An RNA sequence includes 12 bases.
What statement is true about the nitrogen bases in DNA and RNA?
Correct answer: DNA is made up of Adenine, Thymine, Guanine, and Cytosine. RNA has these same bases, except in RNA, there is no Thymine. Instead, Uracil is found.
What is true nitrogen base?
What sequences in the mRNA are required to signal the splicing process?
The pre-mRNA Transcript Introns contain several important and conserved sequences that guide the splicing process: a 5′ GU sequence (the 5′ splice site), an A branch site located near a pyrimidine-rich region (a region with many cytosine and uracil bases) and a 3′ AG sequence (the 3′ splice site).
What is the three base sequence of mRNA called?
Which correctly orders the three main types of RNA used in protein synthesis?
There are three types of RNA: mRNA, tRNA, and rRNA. mRNA is the intermediary between the nucleus, where the DNA lives, and the cytoplasm, where proteins are made. rRNA and tRNA are involved in protein synthesis. Additional RNAs are involved in gene regulation and mRNA degradation.
Why is RNA needed under splicing?
During splicing, introns are removed and exons are joined together. For the eukaryotic genes that contain introns, splicing is required in order to create an mRNA molecule that is capable of being translated into a protein.
Which one is coding sequence in mRNA?
Protein coding sequences are DNA sequences that are transcribed into mRNA and in which the corresponding mRNA molecules are translated into a polypeptide chain. Every three nucleotides, termed a codon, in a protein coding sequence encodes 1 amino acid in the polypeptide chain.
What are the 3 major steps involved in mRNA processing?
What RNA is required under splicing?
Why is RNA splicing important and steps of RNA splicing?
The process of RNA splicing involves the removal of non-coding sequences or introns and joining of the coding sequences or exons. … In eukaryotic cells, RNA splicing is crucial as it ensures that an immature RNA molecule is converted into a mature molecule that can then be translated into proteins.
What is mRNA capping?
What is splicing Class 12?
Splicing is the process of removal of introns and joining of exons in a definite manner.
What is splicing Why is it necessary?
The process by which non-coding regions (intron) on hnRNA are removed and coding regions (exon) are joined to produce mRNA is called splicing. Splicing is necessary in eukaryotes to remove the non-coding introns from hnRNA to produce a meaningful functional mRNA. Prokaryotes do not have introns in the mRNA.
What is capping and tailing class 12?
Adding of an unusual nucleotide methylguanosine triphosphate to the 5-end of heterogenous nucleae RNA hn RNA is called capping. Adding of Adenylate residues to the 3-end in a template independent manner is called tailing.
What is splicing in molecular biology?
Listen to pronunciation. (SPLY-sing) The process by which introns, the noncoding regions of genes, are excised out of the primary messenger RNA transcript, and the exons (i.e., coding regions) are joined together to generate mature messenger RNA.
What is splicing BYJU’s?
Splicing is the process by which introns are excised from pre-mRNA transcript and exons join together to form mature mRNA, which comes out of the nucleus and takes part in protein synthesis.
