Open Question: Homework help (genetics)?
I cant go to the web page that I am supposed to use. It isn’t working. But these are the questions I have to answer.
Someone please help me?
1. What are the biological instructions that determine hair color, eye color, and skin color called?
2. What molecule shaped like a twisted ladder makes up our genetic code?
3. What is a hereditary disease?
4. Let?s say your family had a history of heart disease. Does this mean you would get heart disease too? Would there be anything you could do to lessen your chances?
5.Plants such as wheat, rice, and cotton are being genetically manipulated to be more resistant to insects and diseases. What do you think are benefits or hazards of this new technology?
6.Techniques such as gene-splicing can also be used to synthesize other beneficial chemicals that are otherwise difficult to obtain. What are some of these chemicals and what do they do?

Resolved Question: Is a First Degree AV Heart Block condition even treatable?
Three weeks ago I was diagnosed with a first degree level AV heartblock and sinus arythmia. So far, I’ve had a stress test, an EKG, echocardiogram, pulmonary testing and my cholesterol levels checked (good was low, bad was high, tri was perfect).
The cardiologist I saw today is not taking my concerns about this diagnosis seriously. Google has helped me learn more about the condition but there is no information about how to treat this heart conduction defect. I have shortness of breath, dizziness and am lightheaded. And two months ago I quit smoking (smoker 1 pk a day for 15 years), changed my diet and started trying to walk 30 minutes at least 3 times a week.
All my tests fall within the “normal” range. If its all about a numbers game, how can I be sure my cardiologist, or any cardiologist will help me? So far, the only action taken by my cardiologist was to prescribe some lipitor (I’m 36 with high cholesterol and a family history of congestive heart failure) for me to take.
I also want to add I have two previous brain injuries from car accidents and have been treated for neck and back injuries and dizzines related to those accidents.
I also have a CT scan test scheduled to measure the plague in my heart in two weeks. I told my cardiologist this today at my appointment, and he tried to disuade me by telling me to cancel it. He added that I already know I have high bad cholesterol and that the heart CT scan will only show that amount of plague in my heart and add un-necessary worry.
What kind of cardiologist tries to disuade a patient from getting further testing, knowing my family history of heart disease?
Obviously, I can find more cardiologists to get more opinions. But what more can I do to empower myself knowing what I do know, despite the normal results of all my testing? My cardiologist even told me that my sinus arythmia was a common thing and not to worry.
So I’m supposed to be okay with being short of breath the rest of my life?
Allison, you are wrong when you say there are no symptoms with a First Degree AV Heart Block.
It is a DISEASE of the heart’s electrical conduction system and it has symptoms. The heart’s electrical imulses move through the heart’s chambers slower than normal AND in a very small subset of people, it can progress to 2nd, 3rd, 4th degree heart blocks that are more dangerous.
These are the symptoms of a First Degree Heart Block; lightheadedness, shortness of breath, dizziness, fatigue.
Neither of you have helped me at all. I’m really disappointed. I will have to just figure this out on my own.
