Place the steps involved in the process of bacterial transformation in the correct order. Drag the labels to the appropriate loc
igomit [66]

Answer:

The flowchart is not seen in your question. The labeling cannot be done without seeing the flowchart.

Here are the processes of bacterial transformation:

Explanation:

Bacterial transformation is defined as the change in the properties of bacteria which is caused by the introduction of foreign and naked DNA.

DNA is an hereditary material in organisms that contains their genetic information.

Here are the processes of bacterial transformation:

Step 1: Donor cell forms a Donor cell lyses

Step 2: Donor cell homologous binds to a receptor site on the recipient cell.

Step 3: One strand of donor cell DNA is degraded, and transformed DNA Pairs with homologous region on recipient cell.

Step 4: Finally, recombines with recipient cell chromosome

Nonrenewable resources are used much more prevalently today despite knowing that they pollute and will run out in the future. wh
KIM [24]

We are not using more renewable resources because we have been using fossil fuels since the 18th century and renewable resources are comparatively new. Also, we have limited knowledge about them, so it will take time to change our mindset toward renewable resources.

Based on exhaustibility, there are mainly two types of resources, renewable resources, and non-renewable resources.

Renewable resources are those resources that are replenished while non-renewable resources are those resources that are not replenished.

The non-renewable resources take millions of years to form and once exhausted they cannot be made more.

Examples of renewable resources are solar energy, wind energy, geothermal energy, etc. while examples of non-renewable resources are fossil fuels like coal and petroleum, metals, etc.

Despite the fact that the supply of non-renewable resources like coal and petroleum is limited and they also cause pollution, the use of them is rampant around the world.

The use of fossil fuels is widespread because we have been using them since the 18th century and the use of renewable resources is a very recent phenomenon.

Also, a major hurdle for using renewable resources is the upgrading of current technology to harness these resources.

The newer technologies are generally more expensive to employ, for example, the solar cells used for storing solar energy are made up of elements like silicon, silver, and gallium which are expensive.

Imagine that your lab is synthesizing a new type of cell. One of your colleagues suggests that your synthetic cell should use pr
Gnom [1K]

Answer:

In a scenario in which I have to synthesize a cell and decide why I have to pick one from Prokaryotic or eukaryotic because of their differences in the speed of the process. The characteristics that make it faster in prokaryotic cells are:

The primary transcript in prokaryotes does not undero further processing, so transation can begin immediatly.

Multiple proteins can be synthetized from a single polycistronic MRNA molecule.

Prokaryotes lack a nuclear envelope, so translation can begin on mRNA even before transcription of the mRNA is complete.

Explanation:

The nature of Prokaryotes makes them undergo the synthesizing process quicker than Eukaryotes because they don't require a preliminary process to start it as Eukaryotes have to undergo one. This is because their composition, Eukaryotes are cells without many organelles like mitochondria or even nucleus. this is also the reason for eukaryotes to be slower in the process of synthesizing mRNA because they don't have organelles to process it faster. Finally, because they don't have a nucleus to help them assimilate the mRNA.
