What do we call the process where part of the DNA is saved during replication?
Nataly_w [17]

Answer:

The process where part of the DNA is saved during replication is known as semi conservative replication.

Explanation:

During cell division, a cell must first replicate its DNA (Deoxyribonucleic acid).  When a cell divides into daughter cells , the DNA of the parent cell must be copied because DNA contains the genetic material of an organism. DNA replication is the process in which DNA is copied  during the cell  division cycle.  During replication, the complementary strands of the original double helix DNA are separated and one of the two strands in the original molecule is saved in the new DNA molecule. Thus the new DNA molecule is made of an original strand and a newly synthesized strand. So the DNA replication is known as semi conservative replication. Each strand of the original DNA molecule is referred as the template strand because it provides information for the production of newly synthesized strand. It takes place inside the nucleus of a cell during the s stage  of the cell cycle. During replication, helicase enzyme breaks the hydrogen bonds between the complementary bases (Adenine with Thymine, Cytosine with Guanine) and unwinds the double helix of DNA. The two separated strands create a Y-shaped replication fork and act as templates for the synthesis of new strands of DNA. Enzymes known as DNA polymerases create the new strands.

The genes that masks the effects of other genes
kicyunya [14]

epistatic gene

Anna11 [10]

Answer:

Plant A listens to classical music for three hours each day

Explanation:

  • Music affect plant growth of plants through the vibrations that it creates to the sound waves.Classical music causes more pressure to the sound waves causing vigorous vibrations  which is picked up by the plants speeding up the protoplasmic movement in the cells.
  • The vibrations causes movement of  the plant cells which speed up growth of the plants by stimulating the plants to produce more nutrients enabling them to germinate having more leaves,greater in size and other improved characteristics which means the plant's genetic chromosomes were changed.  
  • Also in the soil  is able to produce good fungi and bacteria encouraging better root development due to healthy vines resulting to vigorous growth and better fruit.
  • Moreover the plants are able to receive special attention and care from the farmer thus enhancing faster growth.
