<span>A. Hershey and Chase used bacteriophages to confirm that DNA was the genetic material in genes.
</span>According to the central dogma of molecular biology, the process of protein synthesis in living organisms follows the order: DNA →RNA→ Protein.Information for synthesis of a particular protein is copied (transcribed) from DNA onto mRNA in a process called transcription, in the cell nucleus.<span>mRNA (messenger RNA) leaves the cell nucleus and enters the cytoplasm where it attaches to a ribosome. tRNA (transfer RNA) begins to decode (translate) the information on the attached mRNA in a process called translation and fetches amino acids corresponding to this information from the pool of free amino acids in the cytoplasm, and brings them to the ribosome where they are joined together into a chain and thus the protein is formed.</span>
Answer: Replication is called semiconservative because each of the original strand is is used as a template for the synthesis of a new strand
Explanation: DNA is a double-stranded helix containing two antiparallel strands that are complementary to each other.
Replication is the process of making identical copies of a DNA molecule. Before replication begins, the double-stranded DNA is first unwound by helicase so that each strand will serve as a template for new strand synthesis.
DNA replication is semiconservative because each DNA strand serves as a template for the synthesis of a new strand, producing two new DNA molecules each one with one new strand and one strand.
Saved and used in the new strand
Answer:
A climate graph displays yearly temperature and precipitation statistics for a particular location. Temperature (oC) is measured using the numbers on the left hand side of the chart. The average temperature for each month is plotted on the graph with a red dot and the dots are then connected in a smooth, red line.
Answer:
Long beaks of medium ground finches allows them to opt for alternate sources of food in times of extremities while this is not the case with the cactus finches.
Explanation:
The medium ground finches have larger beaks and thus apart from small seeds they can also break open the large seed. In case if the small seeds get scarce, a medium ground finch can still survive by taking advantage of feeding on alternate source of food but small beaked birds such as cactus finches shall die out of starvation.
This adaptation of medium ground finches gives it a survival advantage over the cactus finches
