Answer:

If lacO were mutated, what effect would this have on lactose metabolism? The repressor would not properly bind to the operator, and the lac operon would be over expressed. How does the cell recognize that lactose needs to be metabolized? Lactose is converted into allolactose, which inhibits the lac repressor.

According to Wikipedia, In bacteria, transcription and translation can occur simultaneously in the cytoplasm of the cell, whereas in eukaryotes transcription occurs in the nucleus and translation occurs in the cytoplasm.

GIVE BRAINLIEST PLZ! :)

The difference between bacterial and eukaryotic transcription is that in bacteria, transcription and translation can occur simultaneously in the cytoplasm of the cell, whereas in eukaryotes transcription occurs in the nucleus and translation occurs in the cytoplasm.

The main difference between eukaryotes and prokaryotes is that the eukaryotes are well developed and advanced and have different cell organelles and they have different functions in the cell and the prokaryotes are not well developed and they are found in the unicellular organisms.

The unicellular organisms are made of one cell and carry out the processes of life as a single cell and the multicellular organisms are made up of two or more cells that have specific functions to contribute to the life processes.

Therefore, The difference between bacterial and eukaryotic transcription is that in bacteria, transcription and translation can occur simultaneously in the cytoplasm of the cell, whereas in eukaryotes transcription occurs in the nucleus and translation occurs in the cytoplasm.

When a cell is submerged in a hypotonic solution, water osmosis causes the cell to become flaccid.

A semi-permeable membrane is used in the process of osmosis, which allows solvent molecules to move from a solution of low concentration to a solution of high concentration.

Osmosis is a passive process that doesn't require any energy to complete. In order for the concentrations on either side of the membrane to be equal, molecules must shift from an area of greater concentration to one of lower concentration.

Any solvent, including gases and supercritical liquids, can go through the osmosis process.

Therefore, when a cell is submerged in a hypotonic solution, water osmosis causes the cell to become flaccid.

Answer:

A gene consists of enough DNA to code for one protein, and a genome is simply the sum total of an organism's DNA.

Genomic DNA, or gDNA, is the chromosomal DNA of an organism, representing the bulk of its genetic material. ... In research, genomic DNA is useful tools in applications such as PCR, library construction, Southern blotting, hybridizations, SNP analysis, and molecular diagnostic assays.

Answer:

DNA

DNA is the molecule that is the hereditary material in all living cells.

Genes are made of DNA, and so is the genome itself. A gene consists of enough DNA to code for one protein, and a genome is simply the sum total of an organism's DNA.

DNA is long and skinny, capable of contorting like a circus performer when it winds into chromosomes. It's skinny as a whip and smart as one too, containing all the information necessary to build a living organism. In a very real sense, DNA is information.

WHAT IS DNA MADE OF?

DNA is a very large molecule, made up of smaller units called nucleotides that are strung together in a row, making a DNA molecule thousands of times longer than it is wide.

Each nucleotide has three parts: a sugar molecule, a phosphate molecule, and a structure called a nitrogenous base. The nitrogenous base is the part of the nucleotide that carries genetic information, so the words "nucleotide" and "base" are often used interchangeably. The bases found in DNA come in four varieties: adenine, cytosine, guanine, and thymine—often abbreviated as A, C, G, and T, the letters of the genetic alphabet.

How did people find out that DNA is the hereditary material?

DNA was largely ignored for decades after a German chemist, Friedrich Miescher, first isolated the white, slightly acidic substance from the nucleus of cells in 1869. No one knew what DNA's function was—in fact, some doubted that it had a function at all—so they pretty much left the stuff alone.

Very few people thought that DNA could be the hereditary material. Early studies of DNA suggested, erroneously, that the molecule was made up of the same sequence of four bases repeated over and over—ACGTACGTACGT… for example. No one could imagine how such a monotonously simple molecule could contain the information necessary to build a living organism.

But during the 1930s and 1940s, new experiments began to suggest that DNA might, in fact, be important. It turned out that different strains of bacteria can exchange DNA and that when they do certain traits, such as the ability to cause disease in humans, can be passed from one strain of bacteria to another. Scientists also learned that when a virus infects a cell it injects its DNA into the cell, which then produces many copies of the virus, suggesting that DNA contains instructions for building viruses. And they found that different species of organisms have different proportions of bases in their DNA—one species might have DNA that is 30 percent A, 20 percent C, 20 percent G, and 30 percent T, while another might have 20 percent A, 30 percent C, 30 percent G, and 20 percent T. People began to think that genetic information might be written in the differences between the DNA bases of different species.

What does DNA look like?

A DNA molecule is a double helix, a structure that looks much like a ladder twisted into a spiral. The sides of the ladder are made of alternating sugar and phosphate molecules, the sugar of one nucleotide linked to the phosphate of the next. DNA is often said to have a sugar and phosphate "backbone."

Each rung of the ladder is made of two nitrogenous bases linked together in the middle. The length of a DNA molecule is often measured in "base pairs," or bp—that is, the number of rungs in the ladder. Sometimes, this unit of measurement is shortened simply to "bases."The structure of DNA was worked out in 1953 by James D. Watson and Francis Crick, who worked together in the Cavendish laboratory in Cambridge, England. By the time they began their work in the early 1950s, it was clear that DNA is the hereditary material, and scientists were racing to find out more about the long-ignored molecule, picking apart the implications of each new detail. Everyone knew they couldn't really understand how DNA works until they understood how its nucleotide building blocks are put together.

Differentiation in plants and animals involves the specialization of cells for specific functions, and it results in the development of different tissues and organs.

Differentiation refers to the process by which cells become specialized in structure and function. In plants and animals, this process occurs during development and results in the formation of different types of cells, tissues, and organs.

During differentiation, cells undergo changes in gene expression, which leads to the production of different types of proteins and other molecules. These changes can be triggered by various signals, such as hormones, growth factors, and environmental cues.

In animals, differentiation occurs during embryonic development and results in the formation of different types of tissues, such as muscle, bone, and nerve tissue. In plants, differentiation occurs during both embryonic development and growth and results in the formation of different types of tissues, such as root tissue, leaf tissue, and stem tissue.
