Answer:
The statement that is false is b)The nuclear envelope is continuous with the Golgi apparatus.
Explanation:
The nuclear envelope or nuclear membrane is not continuous with the Golgi apparatus; rather it is continuous with the exterior of the endoplasmic reticulum.
Nuclear envelope is a double-layered membrane built from lipid bilayer. The nuclear membrane consists of nuclear pores, which are made up of proteins and majorly function in the passing of selected substances in and out of the nucleus. Hence, all the other statements a,c,d are correct.
The DNA (deoxyribonucleic acid) is the double helical in structure. It has two anti parallel strands of long polynucleotides. The nucleotides are two purines ( adenine and guanine) and two pyrimidines ( thymine and cytosine). These purines and pyrimidines are attached with their complementary. Adenine pairs with the thymine with the two hydrogen bonds and the guanine pair with cytosine by three hydrogen bonds. The two strands are twisted which is responsible for the helical structure. The overall charge on the DNA molecule is the negative charge.
