Answer:

D. Biotechnology

Explanation:

Biotechnology is the use of living organisms in technological applications. It involves using technological practices and principles in manipulating living organisms in order to produce beneficial products.

One aspect of biotechnology is genetic engineering or genetic modification which entails changing the genetic content of an organism to suit desirable effects. Hence, researchers trying to replace damaged genes that cause inherited diseases or to genetically engineer bacteria are studying BIOTECHNOLOGY.

Mandarinka [93]

Answer:

Every organism possesses in its ribosome a protein that is similar to rpl4. This protein has an amino acid sequence that is similar to the sequence of E. coli’s rpl4.

Explanation:

Phylogenetic tree is a diagram which represents the similarities between different organisms and shows their evolutionary histories.

The presence of a similar genetic sequence or amino acid sequence shows that the gene is common in all those organisms. This means that all organisms had a common ancestor through which the gene or amino acid was transferred. The genetic r amino acid sequence remained common in all the different organisms.

Which type of endoplasmic reticulum extends from the nucleus to the cell membrane and holds the ribosomes in place?
larisa86 [58]

Answer:

Rough endoplasmic  reticulum extends from the nucleus to the cell membrane and holds ribosome at its surface.

Explanation:

Endoplasmic  reticulum is of 2 types rough endoplasmic reticulum and smooth endoplasmic reticulum.

  Rough endoplasmic  reticulum is named so because it contain ribosome on its surface as a result rough endoplasmic reticulum play a significant role during translation or protein biosynthesis.

 Rough endoplasmic  reticulum extends from the nucleus that"s why most of the proteins of rough endoplasmic  reticulum is accessed by the nucleus and if any proteins of RER or rough endoplasmic  reticulum is not properly folded or misfolded then specific signals are send from nucleus for the correct folding of proteins of RER.
