Answer:
Structure of bacteria:
Bacteria is a unicellular and prokaryotic organism i. e. made of one cell and no membrane is present around the nucleus. They are found in many shapes such as rods, spherical and cylindrical etc.
Reproduction in bacteria:
In bacteria asexual reproduction occurs such as binary fission. In binary fission, the body of organisms is divided into two equal parts and each part becomes a new organism.
Infection caused by bacteria:
Bacteria cause infection by entering the host cell and starts reproducing and after that they attack on the neighbor cells.
Answer:
1. 100,000,000 pb
2. 3.33%
3. 3.33%
4. 1.11%
Explanation:
1. You just need to multiply the number of genes to the average size: 10,000pb*10,000pb= 100,000,000 pb
2. If 3,000,000,000 equals 100%, we use the rule of three:
3,000,000,000 – 100%
100,000,000 – X
X= (100,000,000*100)/3,000,000,000 = 3.33%
3. It equals the proportion of genes in the total genome, and since a random mutation can occur in any part of the genome, the fraction of gene material equals the probability.
4. Assuming that only one of 3 mutations will result in a protein change, We could assume that is the third part of the probability that this mutations occur in a gene, so: 3.33%/3= 1.11%.
D.
They reproduce in a complicated process.
