high efficiency transformation of intact yeast cells using single stranded nucleic acids as a carrier

1 answer:

7 0

The efficiency of genetic transformation of intact Saccharomyces cerevisiae cells rose to more than 1 105 transformants per microgram of vector DNA and to 1.5% transformants per viable cell utilising a method that produces competent cells using LiAc.

<h3>What is nucleic acids ?</h3>

Biopolymers and macromolecules called nucleic acids are necessary for all known forms of life. They are constructed of monomers called nucleotides, which are composed of a nitrogenous base, a phosphate group, and a 5-carbon sugar. Deoxyribonucleic acid and ribonucleic acid are the two primary types of nucleic acids.

Gene expression, cellular activity regulation, genetic information storage and transfer are the three primary uses of nucleic acids.

The constancy of the chromosome number from one cell generation to the next is maintained through.

vesna_86 [32]

Through mitosis, the number of chromosomes is kept constant from one cell generation to the next.

<h3>What occurs during mitosis?</h3>

A cell divides into two identical daughter cells after duplicating all of its components, including its chromosomes. Due to the importance of this procedure, specific genes carefully regulate each phase of mitosis. Health issues like cancer may develop when mitosis is improperly controlled.

<h3>How many phases of mitosis are there?</h3>

Prophase, pro metaphase, metaphase, anaphase, and telophase are these stages.

<h3>What function does mitosis serve?</h3>

Mitosis' purpose is to divide the genome so that the two daughter cells inherit an identical and equal number of chromosomes.

<h3>Where in the cell cycle does mitosis occur?</h3>

The mitotic phase, which consists of mitosis and cytokinesis and produces two daughter cells, begins after interphase. Despite the fact that the two processes frequently overlap, mitosis occurs before cytokinesis.

Answer:

A more dense material will cause the light to bend more. (dense substances have a higher refractive index)

A less dense material will cause the light to bend less.

The speed of light decreases with more dense materials (the denser the material, the more slowly light travels through it.)

The speed of light increases with less dense materials.

In your own words, explain how energy moves through an ecosystem

Ede4ka [16]

Answer:

The energy in most ecosystems flows through the food chain. In physical ecosystems and most marine ecosystems, the energy flow starts in green plants that harvest some of the sun’s energy. The plants are then consumed by animals, bacteria, and other creatures, which are themselves eaten by other creatures. At each step in the food chain, energy is lost as heat.
