Transposons need to __________________ in order to limit their negative impact on the genome of the host cell. A. control their nucleotide length B. regulate their copy number C. control their target-site choice D. avoid transposing into their own genome

Answers

Answer 1
Answer:

Answer:

The correct answer is B

Explanation:

Transposons need to regulate their copy number to avoid errors with chromosomal pairing during meiosis and mitosis such as unequal crossover.

A typical example of this error is called the Alu Sequence or Elements. Alu elements contain more than one million copies found everywhere in the genome of human beings.

Many inherited human diseases such as cancer are related to Alu insertions.

Cheers!
Answer 2
Answer:

Final answer:

To minimize their negative impact on a host cell's genome, transposons need to regulate their copy number. Unregulated replication could lead to harmful mutations.

Explanation:

Transposons, also known as jumping genes, are sequences of DNA that can move around to different positions within the genome of a single cell. Their movement can cause mutations, which can have negative impacts on the host cell. In order to limit their negative impact on the host cell's genome, transposons need to B. regulate their copy number. If they did not manage this, over-replication of transposons could overload the cell with unnecessary genetic material, leading to harmful mutations or even cancer.

A pharmaceutical company wanted to test a new drug developed to lessen the effects of the common cold. To test this drug, scientists tested 50 volunteers, each of whom was suffering the effects of a cold. Twenty five of the people were given the drug, while the other 25 were given a placebo, a sugar pill. None of the participants knew who was taking which pill. All participants received a pill at 8:00 am daily for the first three days of the study. All participants lived in the same environment, with the same climate, eating the same diet, and having the same level of activity. The severity of the cold, hence the effectiveness of the pill, was determined by the number of tissues each person used within 24 hours. At the end of a seven day period, it was concluded that those with the sugar pill had their symptoms disappear as well as those who had taken the new wonder drug. The executive committee decided to produce the drug anyway thinking that the public would do anything to relieve the symptoms of a cold.

Research Problem: You come across three new species of primates that all cohabitate the same forested area. No one has looked at the behavior of these monkeys before so there is lot to discover about each species. You and a fellow researcher are interested in describing the diet of each of these species (Do they eat fruits? Leaves? Insects? Tree-sap? A combination of sorts?). Your fellow researcher has determined that her hypothesis is that two of the monkeys primarily eat fruit, while one of the monkey species eats tree sap.

Answers

Answer:

there are three different species.

Explanation:

There are three different species of monkey according to the hypothesis because all monkey species have different feeds i. e. one feed on the fruits while the other feed on the tree sap. It also shows that two monkey species have same feed i. e. eating fruits while one specie feeds on tree sap. This hypothesis also shows that no specie of monkey feeds on leaves and insects present on the trees.

bio 102 gleeson The atmospheric ozone layer has been __________since the banning of CFCs (chlorofluorocarbons), but a recent report suggests that this improvement might also be causing _________ in global warming.

Answers

Answer:

decreasing, an increase

Explanation:

Chlorofluorocarbons:  are nonflammable chemicals and have many  uses in our life,  containing atoms of carbon( C), chlorine(Cl), and fluorine (F).

Chlorofluorocarbons damage the earth's ozone layer.

CFCs was banned in 1996. before banned, they were used in aerosols, refrigerators, air conditioners and many other machines.

there continuous use may also cause global warming.

Phage lambda lytic versus lysogenic phases are controlled by two proteins, Cro which leads to lysis and CII which leads to lysogeny. __________ nutrient concentrations in the gut promote E. coli production of proteases that cleave __________ and activate __________. A. low; CII; lysis B. high; CII; lysis C. low; Cro; lysogeny D. high; Cro; lysogeny

Answers

Answer:

The maintainance of the lytic and the lysogenic cycle is done by the Cro and the lambda repressor proteins when the number of bacteria is higher than the number of viruses that is the mode of infectivity or MOI the virus under goes the lytic cycle. This is done by the cleaving of the proteins.

So high nutrient concentration in the gut promotes the growth of the E coli that forms a protease that cleaves the Cro protein and causes the activation of the lysis in the bacteria. So in the high nutrient concentration the bacteria is itself responsible for its lysis.

Where do most organisms that live in water get oxygen from? Give a word, not a formula.

Answers

The organism that live in water get oxygen from the oxygen that is dissolved in water.

What is oxygen?

Oxygen is a gas, that is present 18% in the environment. The oxygen is an important for living beings because all are activities of our body is run by oxygen.

The water also contain oxygen in the dissolved form, which is used by the water organism.

Thus, the oxygen that is dissolved in water.
