Q: how do Retrotransposons Move

A: Transposable elements (TEs) also known as “jumping genes”, are DNA sequences that move from one…

Q: What are telomeres made of and Why do we need telomeres?

A: It refers to the segment of DNA occurring at the ends of chromosomes in eukaryotic cells to prevent…

Q: How are proteins affected if the dna code is mutated

A: When a gene mutation occurs, the nucleotides are in the wrong order. It means that coded genes are…

Q: what is the definition of epigenome

Q: function of a Src homology-3 (SH3) domain?

A: Amino acids can be defined as the building blocks that form polypeptides and ultimately proteins.…

Q: What are elements of role transition from RN to APN?

A: RN is an abbreviation for Registered Nurse and APN is an abbreviation for Advance Practice nurse.

Q: Why is DNA methylation considered an epigenetic phenomenon?

A: Deoxyribonucleic acid (DNA) is a biomolecule found in nearly all living organisms. The structure of…

Q: Is heterochromatin transcriptionally active?

A: Deoxyribonucleic acid (DNA) is the genetic material made up of nitrogenous bases, pentose sugars,…

Q: Is paramutation a cis- or a trans-epigenetic mechanism?

A: In epigenetic, paramutation is a phenomenon in which the expression of gene changes and that…

Q: What are the two types of transposable elements?

A: Transposable elements are known as stretches of DNA molecules and they can move from one place to…

Q: Which features do insertion sequences and transposons have incommon?

A: Transposons are the mobile DNA segments that can move in the DNA of an organism from one location to…

Q: how does cells prevent excess transposable elementmobilization.

A: Transposable elements (TEs) are the small segments of DNA that can move from one position to other…

Q: What features distinguish a transposon from a retrotransposon?How are their sequences different, and…

A: The transposons and retrotransposons are the deoxyribonucleic acid (DNA) sequences that transfer…

Q: What general characteristics are found in many transposable elements?

A: Transposable elements are also known as jumping genes or transposons. A transposon is a segment of…

Q: What are enhancers and How do enhancers work?

A: Transcription is defined as the transcribing the DNA sequence into  RNA sequence by using the DNA as…

Mitochondrial Mutations

A mitochondrion is a cellular organelle that serves as the site for cellular respiration and energy production (ATP or Adenosine Triphosphate). It is a double-membrane-bound organelle and is only present in eukaryotic cells.
