how are dna & mrna alike?

How are DNA and mRNA alike? They are both nucleic acids because they are both made of nucleotides. They both use A,C, and G as their bases. mRNA is a copy of DNA, so it's complementary to it.

Transcription is the process by which the information in a strand of DNA is copied into a new molecule of messenger RNA (mRNA). ... Although the mRNA contains the same information, it is not an identical copy of the DNA segment, because its sequence is complementary to the DNA template.

DNA double helix means that the two-stranded structure of DNA structure is common knowledge, RNA's single stranded format is not as well known. RNA can form into double-stranded structures, such as during translation, when mRNA and tRNA molecules pair. ... RNA molecules, by comparison, are much shorter4.

Solution: Bacteria have both DNA and RNA as their genetic material. The DNA in bacteria, just like eukaryotes is stored in form of a chromosomal structure along with associated proteins and RNA, but as a circular double-stranded structure, unlike the other organisms.

DNA and RNA are two different nucleic acids found in the cells of every living organism. They both each have significan roles to play in cell biology. 2) ﻿DNA also has uracil as its base while the DNA base is thymime. 3) DNA is composed of deoxyribose sugar while RNA is made up of ribose sugar.

RNA. ... Unlike DNA, RNA in biological cells is predominantly a single-stranded molecule. While DNA contains deoxyribose, RNA contains ribose, characterised by the presence of the 2'-hydroxyl group on the pentose ring (Figure 5). This hydroxyl group make RNA less stable than DNA because it is more susceptible to hydrolysis ...

DNA and RNA structure are similar because they both consist of long chains of nucleotide units. ... (1) RNA is single-stranded while DNA is a double-stranded helix. (2) RNA also has uracil as its base while the DNA base is thymine.

During the process of transcription, the information stored in a gene's DNA is transferred to a similar molecule called RNA (ribonucleic acid) in the cell nucleus. Both RNA and DNA are made up of a chain of nucleotide bases, but they have slightly different chemical properties.

DNA uses thymine and deoxyribose sugar, while RNA uses uracil and ribose sugar. While DNA is usually molded into a double-stranded helix, RNA is usually single-stranded, which allows for the binding of anticodons during translation.

Both DNA and RNA are made from nucleotides, each containing a five-carbon sugar backbone, a phosphate group, and a nitrogen base. DNA provides the code for the cell's activities, while RNA converts that code into proteins to carry out cellular functions.

Both DNA and RNA have four nitrogenous bases each—three of which they share (Cytosine, Adenine, and Guanine) and one that differs between the two (RNA has Uracil while DNA has Thymine). ... One of the most significant similarities between DNA and RNA is that they both have a phosphate backbone to which the bases attach.

messenger RNA / mRNA During the transcription process, a single strand of DNA is decoded by RNA polymerase, and mRNA is synthesized. Physically, mRNA is a strand of nucleotides known as ribonucleic acid, and is single-stranded.

In addition, because they are copied from only a limited region of the DNA, RNA molecules are much shorter than DNA molecules. A DNA molecule in a human chromosome can be up to 250 million nucleotide-pairs long; in contrast, most RNAs are no more than a few thousand nucleotides long, and many are considerably shorter.

RNA is somewhat similar to DNA; they both are nucleic acids of nitrogen-containing bases joined by sugar-phosphate backbone. How ever structural and functional differences distinguish RNA from DNA. Structurally, RNA is a single-stranded where as DNA is double stranded. DNA has Thymine, where as RNA has Uracil.

Terms in this set (4) DNA is a polymer composed of nucleotides, whereas RNA is a polymer composed of nucleic acids. DNA contains uracil, whereas RNA contains thymine.

Structural differences. DNA is double stranded, forms a double helix (the two strands spiral around each other) is stable and stays in the nucleus. RNA is single stranded (except in rare cases), can fold into complex 3D shapes, is relatively unstable and can leave the nucleus.
