Answer:
B. Base pairing occurs within an RNA molecule to give RNA the three-dimensional shape needed for specific functions.
Explanation:
Ribonucleic acid, known as RNA, is a type of nucleic acid found in living systems. In opposition to the other type of nucleic acid (DNA), RNA is a short single stranded molecule. Both DNA and RNA are made of nucleotides, composed of a phosphate group, nitrogenous bases and a pentose sugar.
The presence of ribose sugar and Uracil base in RNA instead of deoxyribose sugar and thymine base respectively structurally differentiates the molecule from DNA. However, base pairing occurs within the RNA molecule to form the three-dimensional shape of the RNA, which is key to the specificity of its function.
Answer:
A.30
Explanation:
According to Chargaff's rule there is the same number of Thymine bases as there are of adenine
so we have 120 adenine and 120 thymine
300-120-120=60
those 60 base pairs are represented by cytosine and guanine which also pair with each other according to chargaff's rule they're equal in number
60/2=30 guanine bases
The nucleus is inside of a cell and is enclosed with the cell membrane
