Answer:
RNA molecules are made of nucleotides. (Ans. C)
Explanation:
RNA, which is also known as ribonucleic acid is found in cytoplasm of the cell, and synthesized in the nucleus. It is shorter, and a single stranded molecule. It is composed of one or more nucleotides which are linked together by phosphodiester bonds.
In RNA, the ribonucleotide contains pentose sugar ribose, four nitrogenous bases (A,U,C,G), and a phosphate group. RNA plays many types of role in cells, but mainly involved in the translation process, and it's regulation which is known as protein synthesis.
Answer:
Explanation:
Replication forks from the same origin of replication extend from the beginning of the strand to the end where the enzyme helicase helps to move the replication fork unwinding DNA double helix structure by breaking the hydrogen bonds between the Nitrogenous bases.
DNA strand is used as template for the leading strand at one fork and for the lagging strand at the second fork. New DNA is synthesized from 5' to 3' on the leading strand.
The strand is made continuously forward in the direction of the replication fork while the other strand is made in 3' to 5' direction and been referred to as ozazaki fragments.
In order for a cell to divide successfully, the cell must first...duplicate its genetic information (DNA).
Epithelial tissue covers the outside of the body and lines organs
This type of tissue forms a layer of cells known as the endothelium lining such as skin
