If the base-pairing in DNA becomes non-complementary such that purine bases can pair with one another and pyrimidine bases can pair with one another, the 1:1 ratio of purine to pyrimidine bases in DNA will no longer hold.
Due to the complementary base-pairing rule, the ratio of purine to pyrimidine bases in DNAs is usually 1:1. This is because Adenine always pairs with Thymine while Guanine always pairs with Cytosine.
Once this base-pairing rule is removed and becomes purine-purine and pyrimidine-pyrimidine pairings, then it becomes unnecessary for the ratio of purine to pyrimidine bases to be 1:1.

IF a man with blood type A, one one of whose parents had blood type O, marries a woman with blood type AB, what are the putative genotypes of the offspring?
Answer:
The 1st child will surely have AA,The 2nd might have AB/OB and the last one will surely have OB
Explanation:
I studied at school like 2 yrs ago
I am sure
Answer:
If the man has blood type A one of whose parents had blood type O then he must be having the genotype IAi and the woman with blood group AB would have genotype IAIB. So if they produce offspring than the putative genotype of the offspring would be IAIA, IAi, IAIB, and IBi.
Explanation:
IA i
IA IAIA IAi
IB IAIB IBi
Therefore out of four offspring, two offspring would be having A blood group, one offspring would have AB blood group and one offspring would have B blood group.

Which of the following best explains the strength of collagen fibers?
I'm really sorry but you didn't provide any options...
Collagen fiber is the fiber in the extracellular matrix of connective tissues characterized by being elongated and made up of collagen glycoproteins. It is typically arranged in branching bundles of indefinite length. It is a strong insoluble fiber. It occurs in the skin, tendon, ligaments, bone, and cartilage.

which of the is a correct way to label speed
Answer:speed In m/s
Explanation:
n
Answer: And the best way to label the line segments are with their endpoints, and that's another word here. So a point is just literally A or B, but A and B are also the endpoints of these line segments, 'cause it starts and ends at A and B. So let me write this A and B. A and B are endpoints, another definition right over here.

Explain why sickle cell anaemia is persistent in the tropics yet it is lethal and these areas have high malaria Providence.
Sickle cell anemia is persistent in the tropics because those with sickle cell anemia cant contract the malaria virus because of the shape of their blood cells, and this is advantageous in the tropics where there are more malaria cases. So those with sickle cell anemia live to pass on their genes.

Question 1) Discuss how compounds in different types of organisms can be used to benefit people? ( Will Mark Brainliest).
Osteoporosis is more prevalent among women than men because women generally
have more bones in their bodies than men have.
take in more calcium than men take in.
have lower bone mass than men have.
exercise more than men do
Answer:
Have lower bone mass than men have
Explanation:
Osteoporosis is a bone thinning disease that is more prevalent among women than men and typically occurs after 50. The reason women are more likely to get the disease than men is because after 50 many women have gone through or are going through menopause. Menopause causes the ovaries to produce less estrogen which is what had previously been promoting bone density.
The other answers are incorrect because...
A: have more bones in their bodies than men have: for the most part everyone has the same amount of bone in there body (although there are diseases that cause a persons bones to fuse together making them have fewer bones than the average person)
B: take in more calcium then men take in: more calcium would actually cause someone to be less likely to get osteoporosis because it strengthens the bones.
C: exercise more than men do: Osteoporosis is more common in malnourished women and women who do not get regular physical activity to strengthens there bones. So getting more exercise would actually lessen the chance of getting osteoporosis.

How do the baby’s respiration and circulation change when the baby is born?
Answer:
Oxygen and carbon dioxide flow through the blood in the placenta. Most of it goes to the heart and flows through the baby's body. At birth, the baby's lungs are filled with fluid. ... Increased oxygen in the lungs causes a decrease in blood flow resistance to the lungs.

1) BbEE
2) BbEe
3) BbEe
4) bbEe
The Punnett square is a diagram used to predict the genotypes of a particular breeding / etc. For example, in the top left BE and BE becomes BBEE because you take both letters and put them together. Here, the Bs will go first and the Es. In the one to the right of that, Be and BE becomes BBEe as you put the Bs and Es in order, but you also have to make sure that lowercase bs go after uppercase bs, and etc.

What is the relationship between DNA, chromosomes, and
the nucleus?
Answer:
In the nucleus of each cell, the DNA molecule is packaged into thread-like structures called chromosomes. Each chromosome is made up of DNA tightly coiled many times around proteins called histones that support its structure.
Other Info That Might Help:
In contrast, in eukaryotes, all of the cell's chromosomes are stored inside a structure called the nucleus. Each eukaryotic chromosome is composed of DNA coiled and condensed around nuclear proteins called histones. Humans inherit one set of chromosomes from their mother and a second set from their father.

Do turtles have exoskeleton?
Answer:
Mark me brainliest （⌒▽⌒）Explanation:
The turtle shell isn't like any other protective element of any living animal: it's not an exoskeleton, like some invertebrates have, nor is it made of ossified scales like armadillos, pangolins, or some snake and reptile species. ... The turtle shell is actually a peculiar evolution of a turtle's bone structureNo. Turtles are vertebrate animals with internal skeletons. Even the shell is made of bone covered by a thin layer of tissue and keratin scutes (material similar to your fingernails). The entire skeleton is on the inside. A turtle’s shell is no more an exoskeleton than your own skull is.
