Question

what is transcription,translation,translocation ?????​

Answer 1

Transcription, translation and translocation can be described as follows:

Explanation:

• In molecular biology, the process of making RNA from DNA is termed as transcription. In eukaryotic organisms, this process occurs in the nucleus of a cell.

• In molecular biology, the process of making proteins from mRNA is termed as translation. This process occurs in the ribosomes of a eukarytoic cell.

• Translocation is referred to a process when a part of the chromosomes moves to another chromosome causing a mutation to arise.

Explanation:

Transcription :

• refers to the first step of gene expression where an RNA polymer is created from a DNA template. This reaction is catalyzed by enzymes called RNA polymerases and the RNA polymer is antiparallel and complementary to the DNA template. The stretch of DNA that codes for an RNA transcript is called a transcription unit and could contain more than one gene

Translation :

• The mRNA formed in transcription is transported out of the nucleus, into the cytoplasm, to the ribosome (the cell's protein synthesis factory). Here, it directs protein synthesis. Messenger RNA is not directly involved in protein synthesis − transfer RNA (tRNA) is required for this. The process by which mRNA directs protein synthesis with the assistance of tRNA is called translation.

Translocation :

• Translocation is a type of chromosomal abnormality in which a chromosome breaks and a portion of it reattaches to a different chromosome. Chromosomal translocations can be detected by analyzing karyotypes of the affected cells.
