Enzyme hot spring graphing what enzymes probably came from the digestive tract of the mondoni

AURORKA [14]

I found the full exercise on the internet and it describes that there are three enzymes and you want to know which are the two enzymes from the digestive tract of the mondoni and which one is the enzyme from a hot spring.
Attached are two graphs from the analysis of the activity of these enzymes regarding temperature and pH. I found these graphs with the full exercise.
The enzymes that probably came from the digestive tract of the mondoni were enzymes A and B. These enzymes were resistant two lower levels of pH which indicates that they could be present in a digestive tract, which tends to be acidic, while the enzyme C does not tolerate lower pH levels. Enzymes A and B were also more active when in lower temperatures that match temperatures of a normal living organism, whereas enzyme C was more active in higher temperatures matching its probable provenience - a hot spring.

Where in your body is there an enzyme that does function at a high or low pH? What is the name of the enzyme and its function?

Tanzania [10]

The enzyme pepsin functions with a very low pH of around 2. It is found in the stomach, with the acidity coming from the hydrochloric acid present there. it breaks proteins into amino acids.

Genetically engineered pork has a higher flesh-to-bone ratio. Which of the following sentences explains how pork is genetically

Oksanka [162]

The answer is A) the desired gene is inserted into the genomes of the pork.

The techniques of genetic engineering are used to introduce hybrid genes for some desired substance or protein or trait into other organisms. Here, the desired gene is inserted into pork's genome and as a result, it has a higher flesh-to-bone ratio.

- B) is not the right answer because it is not necessary to change all the genes in the pork genome or it will be transformed into totally different organism.

- C) is not the right answer because the pork does not have plasmids.

The human genome contains about 3 billion base pairs. During the first cell division after fertilization of a human embryo, S ph

Nataly [62]

Answer:

5556

Explanation:

If a DNA polymerase synthesizes in average 50 nucleotides/second, that means that in three hours (10800 seconds) it synthesizes about 540000 nucleotides.

However, if the human genome is composed of 3000000000 (3 billion) base pairs (nucleotids), the minimum number of DNA polymerases (working in the same number of origins of replication) to finish the duplication of all the genome in three hours is 5555,5. (3000000000/540000). As we know there is no half polymerase, so we round to 5556.

5556 molecules of DNA polymerases acting on 5556 origins of replication are needed.

In cellular reproduction, ___ ALWAYS occurs in 5’ to 3’ direction

attashe74 [19]

Answer:

DNA replication

Explanation:

DNA replication is the process whereby the genetic material (DNA) duplicates itself into two identical copies. This process must occur prior to any cellular division (meiosis or mitosis) in order to ascertain that each daughter cell gets an even and correct amount of DNA.

The process of DNA replication begins with the unwinding of the double stranded DNA molecule into two single strands of DNA. One strand called leading strand runs from 3'-5' while the other strand runs from 5'-3'. However, DNA replication proceeds in the 5'-3' direction.
