Segments of DNA can be cut by using enzymes
"Anaphase I" is the phase of meiosis among the choices given in the question that tetrads are separated as homologous chromosomes are pulled to opposite poles of the cell. The correct option among all the options that are given in the question is the second option, or option B.
I hope it helps you!
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.
Answer:
I do not agree with this statement.
Explanation:
Plants and some bacterias are autotrophic, meaning that they manufacture their own food from basic elements using an energy source in an anabolic process. Plants mostly utilize sunlight which they trap with the help of their green pigmentation called chlorophyll. Bacteria on the other hand mostly get their energy source by splitting chemical compounds, utilizing the liberated bond energy of the compound (examples is the sulfur bacteria) to fuel their food building process.
