Answer:
100 units
Explanation:
The parent cell holds 200 units of DNA. During the process of cell division, this amount is distributed between the resulting daughter cells, with each cell obtaining half of the DNA present in the original cell.
As mitosis yields two daughter cells, each one will receive 100 units of DNA.
Response:
The lysogenic replication cycle is a distinct procedure in the replication of the T7 virus.
Clarification:
The T7 virus targets bacteria (bacteriophage). Unlike viruses that infect plants and animals, it utilizes two cycles for replication within the host: the lysogenic cycle and the lytic cycle.
Virulent phages undergo the lytic cycle, leading to cell death through lysis.
The lysogenic cycle involves temperate bacteriophages, which can integrate with the host chromosome to form a prophage. This prophage replicates alongside the host cells' genetic material until it is prompted to switch to the lytic phase, producing new viruses that subsequently exit the cell through lysis.
This method of insertion into the host genome is termed lysogenic replication and is unique to bacteriophages.
The correct option is: A. Species A possessed larger jaw muscles than species B.
Significant jaw muscles are linked to a more primitive diet. It is thought that the reduction of jaw muscles is part of the evolutionary process. This is a way to create room for a larger brain.
mRNA functions as the messenger that conveys DNA's instructions to ribosomes, which are responsible for protein synthesis. Meanwhile, tRNA aids in transporting the requisite amino acids to the ribosomes. Essentially, mRNA specifies the amino acids required and their sequence, while tRNA collects these amino acids and delivers them to the ribosomes.
