Answer:
There are histones in the nucleus that DNA coils around. The part of the DNA that is coiled around the histones is not accessible, and cannot be expressed in that cell. DNA that is not wrapped around a histone can be transcribed.
Explanation:
They are not something that you prevent from being made in your body. They are automatically made when you eat food that is not automatically converted into calories. This is used for energy later on for you body.
But too much of triglycerides is bad for you. This condition is called hypertriglyceridemia. Your doctor can detect if you have this condition by simply running a lipid panel (a blood test) that measures your overall cholesterol, you LDL and HDL cholesterol, and also measuring your triglycerides.
If you do take this test, they will make you fast for about 8 hours. They make you do this because triglycerides are usually lowest after you fast but goes up really high after a big meal (like a Thanksgiving Dinner!).
(Extra: your triglycerides are measured in milligrams per deciliter (mg/dL) and if your levels are:
BELOW 150 -----------------Healthy
150-199 -----------------------Borderline
200-499 ---------------------High
500+ --------------------------Very High
Most people are under 200, so in the end, you don't have to worry about your triglyceride levels.

In this Josephine is correct. While red will most commonly occur, if the 'r' is there then under Mendel's rules, a 3 to 1 ratio will appear. Ie for ever 3 red flowers, one flower will be the other colour.
'RNA is transcribed and translated in the cytoplasm', 'transcription produces an mRNA ready for translation' and 'RNA is proofread for errors' occur in prokaryotes, whereas '5′ cap, 3' poly-(A) tail and RNA splicing' occur in eukaryotes.
The prokaryotic cells (e.g., bacterial cells) do not contain cell nuclei, thereby the messenger RNA (mRNA) must be transcribed and translated in the cytoplasm.
During prokaryotic transcription, the RNA transcript is proofread for errors. In bacteria, DNA polymerases proofread the transcript by using their 3’ → 5’ exonuclease activity.
In eukaryotic cells, RNA processing consists of several mechanisms:
- A 7-methylguanosine cap (5′ cap) is added to the 5′ end of the precursor messenger RNA (pre-mRNA).
- A 3' poly-Adenine (A) tail is added to the 3' end of the pre-mRNA.
- Both the 5′ cap and 3' poly-(A) tail protect the RNA transcript from its degradation by exonucleases.
- Eukaryotic RNA splicing consists of the removal of non-coding regions called 'introns' and subsequent splicing of the protein-coding regions called 'exons'.

Answer:
The Markonikov's rule determines where to add a nucleotide in the reaction
Explanation:
In organic chemistry, the organic carbonyl reactions are governed by a set of rules. One of them is the Markovnikov's rule. Basically, the rule determines where the addition of the nucleophile and a hydrogen will take place in a chemical reaction involving alkene addition. In the reaction principles, there are rules to follow based on the syn and anti addition. This refers to which side the two groups will face. they add to the same side an called the syn. When its opposite side, then its anti.
