Answer:

A DNA fragment is inserted into a plasmid.

The DNA fragment replicates during cell division.

The plasmid enters a host bacterial cell.

The plasmid becomes part of a host cell's chromosome.

A host cell produces a protein that it would not have produced naturally.

Explanation:

Recombinant DNA is the DNA molecules formed invitro or lab condition with the help of a plasmid, bacterial cell as host and a desirable gene or DNA fragment by the technique of genetic engineering or recombination. This is also known as molecular cloning.

The correct order of steps in the DNA recombination process are as follows:

The desired DNA fragment is inserted into a vector or plasmid.

The DNA fragment replicates during cell division.

The plasmid enters a cell of host bacterial

The plasmid becomes part of a host cell's chromosome.

A host cell produces a protein that it would not have produced naturally.

At the coordinates 45 degrees W & 72 degrees N it is 9:32 AM. What time is it at the coordinates 75 degrees W & 45 degre

garik1379 [7]

Answer:

The correct option is;

7:32 AM

Explanation:

The information given are;

The time at 45 degrees W and 72 degrees N = 9:32 AM

The variation of time with lines of longitude is given as 15 degrees for each 1 hour variation, therefore, where we have the other location at 75 degrees W and 45 degrees S, the difference in the longitude = 75 - 45 = 30 degrees west of the initial location

Moving west is in the opposite direction of the Earths rotation, therefore, we subtract 1 hour for every 15 degrees giving 30/15 = 2 hours subtracted

The time at 75 degrees W and 45 degrees S is therefore, 9:32 AM - 2 hour = 7.32 AM

The latitude of a place left out in the calculation of the relative time of a place.

Refer to the following five terms to answer the following questions. Choose the most appropriate term for each phrase. Each term

soldi70 [24.7K]

Answer: 3. C. mitochondrion

Explanation:

Mitochondrion in a cell is defined as the powerhouse of the cell which provide energy to the whole cell.

A mitochondrion is has a membranous layer and bean-shaped organelle that is the “energy transformer” of the cell. They contibute to the biochemical processes of the cell called cellular respiration. They works as a digestive system which takes nutrients, breaks them into several energy rich molecules for the cell.

Hence, the correct answer is 3. C. "mitochondrion".

When two genes from two different people are sequenced and aligned, it is discovered that there are multiple sequence difference

REY [17]

Answer:

The best answer to the question: What is the most likely explanation for this observation, would be, B: RNA processing removes the different segments from the mRNA molecules of each person prior to translation.

Explanation:

In order for cells to work, they depend on one of the four major macromolecules; proteins. These proteins are the messengers that carry out genetic commands from the DNA and they will ensure that all processes, including transcription and translation of new proteins, are carried out correctly. In order to produce proteins, the first step is for the DNA to be transcribed into mRNA, a nucleic acid that carries out the information on the DNA for protein generation. Once transcription stops, mRNA undergoes a series of clipping and reorganizing steps that will ensure that when it is decoded for protein formation, the process will be successful. These control steps are all part of the RNA processing mechanism that enures mRNA will successfully be translated into working proteins.

The reason why from genes of different people, a very similiar protein chain may result, is also explained from the fact that codons (a grouping of three nucleotides present in mRNA), when read by ribosomes, and coupled by tRNA, can pair these codons with similar amino acids. Thus, one codon, or similar codons, may code for a singular amino acid. However, mechanisms in the cells prevent these kinds of anomalies, by repairing the mRNA sequence before it is translated into protein.
