In eukaryotes, what types of modifications occur to pre-mRNAs?

Q: What is RNA splicing?

A: RNA is a long chain of ribonucleotides connected together via phosphodiester bonds. It works in gene…

Q: Why will a mistake in the RNA code alone not become a mutation?

A: A change in the genetic code is called a mutation when it becomes a permanent part of the genome of…

Q: What are RNA polymeraseII in transcription in eukaryotes?

A: RNA polymerase {or the DNA dependent RNA polymerase} was discovered by Weiss and Hurwitz in the year…

Q: How do bacteria ensure the start codon of the mRNA is positioned properly during translation…

A: The translation is defined as the process that generates a new polypeptide from mRNA with the help…

Q: Which of the following is a possible consequence of a mutation that introduces a premature stop…

A: The stop codons are the specific genetic codon that do not codes any amino acids during the…

Q: Why can translation in prokaryotes begin before transcription ends?

A: Prokaryotes are single-celled organisms. They consist of the domains Bacteria and Achaea. The…

Q: in a eukaryote cell, what do we call the DNA sequence that the specific transcription factor binds…

A: The transcription is the process by which RNA is produced from the DNA template. In case of…

Q: Codons 24 to 66 represent an intron.  At what point in the process of protein synthesis are introns…

A: Transcribing DNA to RNA is the initial step in a long process that finally synthesizes functional…

Q: What is the function of the anticodon of a tRNA?

A: tRNA is basically a messenger molecule that helps in decoding of mRNA and helps in the formation of…

Q: Which part of the central dogma is achieved by the process of translation?

A: The central dogma of molecular biology is a foundational system that depicts the flow of hereditary…

Q: What could be the effect of a deletion, substitution or addition that alters the sequence of the…

A: Stop codon is a nucleotide triplet which is present in mRNA. This is also known as termination…

Q: How do eukaryotic cells ensure the start codon of the mRNA is positioned properly during translation…

A: The initiation of protein synthesis consists in the recruitment of a ribosome initiator tRNA complex…

Q: ist the three ways in which eukaryotic mRNA is modified.

A: Messenger RNA (mRNA) is defined as a single-stranded RNA molecule that will correspond to a specific…

Q: Give an account of post transcriptional modification of a eukaryotic Mrna?

A: RNA stands for ribonucleic acid and it is a type of nucleic acid. Some of its important function…

Genomics

Genes are responsible for transmitting the characters located on the chromosomes from one individual to another across the generations. Genetics is the study of different genes that are involved in different functions. Genetics is a branch of biology that studies genes, genetic diversity, and heredity in living organisms. The genetic system consists of genetic notations, which is a system of signs and symbols. Genotype refers to the organism's genetic composition, and phenotype refers to the observable property of the organism.
