In your own words, describe the purpose and process of translation. The purpose of translation is… The process of translation is

kondaur [170]

Answer:

the purpose of the translation is to make proteins. proteins are responsible for making bones, muscles, cartilage, skin and blood. proteins are synthesized from the information in a mRNA.

Process of translation

it happens in 3 phases

initiation: the small ribosomal subunits binds to the start of the of the mRNA sequence. then a tRNA molecule carrying the amino acid methoionine binds to start codon of the mRNA sequence. after that large ribosomal subunit binds to form the complete intiation complex.
elongation: the ribosome continues to translate each codon in turn each corresponding amino acid is added to the growing chain and linked via bond called peptide bond. elongation continues untill all the codons are read.
termination: it occurs when the ribosome reaches a stop codon. since there is no tRNA molecules that can recognise these codons the ribosome recognises that translation is complete.

after these 3 phases a new protein is realeasd

A certain restriction enzyme digest results in DNA fragments of the following sizes: 4,000 bp, 2,500 bp, 2,000 bp, and 400 bp. S

Paladinen [302]

Answer:

Smaller the size of the DNA fragment, farther it moves during electrophoresis. The sketch of the position of the fragments has been drawn in the figure below.

Explanation:

As we know DNA is a negatively charged molecule. So during electrophoresis the fragments move towards the positive electrode because opposite charges attract each other.

Different fragment move different distances according to their size during the electrophoresis. Smallest segment travels the largest distance in the gel medium while the largest one travels least distance.

In the question there are four DNA fragments with base pairs 4000, 2500, 2000 and 400 so the smallest segment with 400bp will be farthest from the starting point and the largest fragment with 4000bp will travel least distance in the gel medium. Their respective positions are shown in the figure below. The starting point is near the negative electrode.
