How many hydrogen bonds will be involved in base pairing in a DNA molecule of 50 base pairs that contains 15 cytosine bases

Answers

Answer 1

Answer:

Answer:

The number of hydrogen bonds involved will be 39

Explanation:

There are 4 types of bases that exist in a DNA, which are adenine, thymine, guanine and cytosine. Double stranded DNA molecules have these bases attaching specifically to one another; adenine only binds to thymine and vice versa while guanine only binds to cytosine and vice versa. These two bases bonding together are referred to as base pairs and the type of bond here is the hydrogen bond. There are double bonds between the adenine and thymine base pair while there are triple bonds between the guanine and cytosine base pairs.

Thus, when there are 13 cytosine bases in a DNA molecule, the number of hydrogen bonds present in the resulting base pairs will be 13 × 3 (because cytosine binds with a triple bond to guanine).

13 × 3 = 39

The number of hydrogen bonds involved will be 39

Answer 2

Answer:

Final answer:

So, in a DNA molecule of 50 base pairs that contains 15 cytosine (C) bases, there would be a total of 115 hydrogen bonds involved in base pairing.

Explanation:

In DNA, base pairing occurs between complementary nitrogenous bases. Adenine (A) pairs with thymine (T), and cytosine (C) pairs with guanine (G). Each base pair is connected by hydrogen bonds.

In a DNA molecule of 50 base pairs with 15 cytosine (C) bases, you can determine the number of hydrogen bonds involved in base pairing as follows:

1. Each adenine (A) pairs with thymine (T) and forms two hydrogen bonds.

2. Each cytosine (C) pairs with guanine (G) and forms three hydrogen bonds.

So, for the 15 cytosine (C) bases, you would have 15 pairs of C-G base pairs, and for the remaining 35 bases, you would have 35 pairs of A-T base pairs.

Total hydrogen bonds involved in base pairing:

(15 pairs of C-G base pairs * 3 hydrogen bonds per pair) + (35 pairs of A-T base pairs * 2 hydrogen bonds per pair)

= (15 * 3) + (35 * 2)

= 45 + 70

= 115 hydrogen bonds.

So, in a DNA molecule of 50 base pairs that contains 15 cytosine (C) bases, there would be a total of 115 hydrogen bonds involved in base pairing.

Carbon dioxide diffuses into the ocean carbon cycle via the air-sea surface exchange. Molecules of CO2 enter the ocean by diffusing into the surface waters and dissolving. The amount of CO2 that diffuses and dissolves in the surface water depends on several variables. Scientists have noted that sea more CO2 diffuses and dissolves in colder sea surface water and less CO2 diffuses and dissolves in warmer water. Let's assume the predictions of scientists predicting a warming climate are true. Can you predict the outcome if average ocean temperatures increase as well? Include the effects on appropriate components of the biosphere as well as the hydrosphere.

Answers

Warmer oceans would mean less dissolved CO2 as well as other gases such as oxygen in the global ocean. Lower CO2 would result in a decrease in photosynthesis of autotrophs living in the oceans.

A critical need of society is one that is

Answers

People who respect critical thinking make up a critical society, and a critical need is anything that is urgent or necessary.

What is critical need of society?

Critical sociology aims to deconstruct old social power structures through analyzing texts, artworks, and other forms of media.

This is distinct from other sociological approaches, which frequently emphasize description over criticism.

Social workers must be able to assess each situation impartially by gathering data through observations, interviews, and research.

Social workers can make educated judgments, find the greatest resources, and create the best plans to assist clients by thinking critically and without bias.

Promoting critical thinking is crucial, and doing so through the eyes of cognitive science paints a clearer picture of what proponents for critical thinking are actually attempting to advance.

Therefore, a critical need of society is one that is urgent or necessary.

Scientists often test their hypotheses with controlled experiments. which of these is a rule for conducting a controlled experiment? a. change at least two variables at a time
b. keep all variables constant
c. change as many variables as possible
d. change only one variable at a time

Answers

Changing only one variable at a time is a rule for conducting a controlled

experiment.

Controlled experiment involves the use of dependent and independent

variables . Changes in the independent variable brings about a

corresponding change in the dependent variable which is then recorded.

It is however important to note that changing more than only onevariable at

a time won't accurately determine if the changes in the results were as a

result of one cause. This is why only one variable has to be changed at a

time.

A dedicated surgery suite must be used for which type of surgery?

Answers

Major survival surgery on non-rodent mammals

Major survival surgery in non-rodent mammals must be conducted in dedicated facilities. Major survivalsurgery penetrates and exposes a body cavity, produces substantial impairment of physical or physiologicfunctions, orinvolves extensive tissue dissection ortransection (e.g., laparotomy, thoracotomy, jointreplacement, and limb amputation). The ultimate decision to classify a surgery as major or minor will bemade by the IACUC. Investigators cannot perform major survival surgery in non-rodent mammals in theirown laboratories, but must make use of IACUC approved survival surgery suites that meet federal standards.Major operative procedures on non-rodents will be conducted only in facilities intended forthat purposewhich shall be operated and maintained under aseptic conditions. Dedicated surgery suites must be1approved by the IACUC priorto use and inspected semi-annually. Contact the IACUC office for additionaldetails regarding dedicated surgical suites and major versus minor surgical classifications.

Based on each person's statements, identify which of the following you AGREE with, and then explain your reasoning. Courtney: “It is obvious that everything that eats plants would die but all the other organisms on the island would be okay.” Jose: “Courtney I think the organisms that eat plants would just learn to eat other things. So initially they might decline in numbers but eventually, their numbers would increase back to their current amount.”Raquan: “I have to disagree with both of you. I think that all of the organisms on the island would die, because at some point even the mammals who don’t eat plants directly would ultimately discover that what they usually ate has already died.” Mike: “I kind of agree with Courtney, except I don’t think that all of the things that eat plants will die. I think the things that eat both plants and animals would live and only those that can’t or won’t eat animals will die.” Keisha: “Mike is right. I would add that since there are fewer things for the larger mammals to eat that we would ultimately see fewer of them on the island.” Alex: “I argue that organisms that eat plants would learn to swim so they can eat the seaweed and algae in the water.”Plzz explain your reasoning!!
