The restriction enzymes that cut the bacteriophage DNA cannot cut the bacterial chromosomal DNA. Explain this statement.

The bacteria can cut the viral DNA at its specific restriction site but protect their own chromosomal DNA by modifying its bases and blocking the restriction enzyme. This process is called methylation (adding a -CH3 group) to prevent binding of the enzyme.

Which statements about cells are true? a. Cells are the basic unit of all living things. b. Cells have unique functions and features. c. All cells have some recognizable similarities. d. Every single cell works like a small factory. e. Cells follow a genetic DNA blueprint to construct an organism. f. Cells are composed of different parts called organelles

Answer: All the statements that are provided here are true when a cell is taken into consideration.

Explanation: The cells are known to be the basic structure and functional unit of the body. They have their unique functions based on the different organs in which they are located.

There are some recognizable similarities like structure for the cells. The cells need energy for working and it acts as a small factory. The replication of DNA acts as a blueprint to construct new cells to form an organism.

Every cell of the body function with the help of some small organelles like Golgi apparatus, mitochondria et cetera.

Explain how DNA forms chromosomes in eukaryotic cells?

The DNA is divided into different linear bundles called chromosomes that are separated by spindle during the nuclear division of the DNA. They condensed into highly structured coil. The coil tightens until the DNA creates a proper segregation during the mitosis stage and cell division.

Water is the most abundant molecule found in living organisms. Most mammals, in fact, are approximately 70% water by weight. About two-thirds of this water is present inside cells. The other one-third is present outside cells (e.g., in blood plasma or other body fluids). Why is water so important to cells?. . A.Water determines which proteins are translated from the cellular DNA.. . B.Water is stored in the cells to be used when the organism gets thirsty.. . C. Almost all the chemical reactions in life processes occur in solutions with water.

The answer is letter C. Almost all the chemical reactions in life processes occur in solutions with water.

Water is known to be the universal solvent. Because of its high polarity, it can easily dissolve and bond with other solutes. It makes it easier for the chemical process that is happening inside the body

According to advocates for the use of genetic engineering, which is an example of the importance of recombinant DNA technology.A. Genes from nuts used in other organisms can affect allergies.B. The increase of patents drives the seed cost.C. There is a diminished opportunity for organic agriculture.D. There is a reduced use of pesticides, herbicides, and fertilizers

The best answer is D. reduced use of pesticides, herbicides, and fertilizers. Genetic engineering targets mostly problems from agriculture to increase yield, delimit use of chemicals in pesticides and thus, increase our economy. Decreased use of chemicals in agriculture will also benefit for our health. These goals are only a few of what genetic engineering wants to achieve and prove.

While investigating a break-in, the police discover that the intruder was cut on the broken window that he or she used to enter the house and left a sample of blood behind. Soon after the crime, the police apprehend a suspect and obtain a DNA sample. Which process is most likely to be used to determine whether the blood on the glass belongs to the suspect? PCR analysis STR analysis mtDNA analysis Y-chromosome analysis

Answer:

The correct answer would be STR analysis.

STR or Short Tandem Repeats analysis is one of the commonly used DNA analysis molecular technique.

Short Tandem Repeats are the repeating units of two to thirteen nucleotides present in particular loci on DNA, especially in microsatellite region.

This analysis counts the exact number of repeating units present in different samples based on which it helps in comparing the DNA samples of different individuals.

In forensic science, it is used to compare the DNA found at the crime scene with the DNA of the suspect.
