How does the structure of DNA and RNA differ?

How does the structure of DNA and RNA differ?

DNA is a double helix, made of two, joined strands forming a structure like a twisted ladder. RNA is only a single strand and comes in a variety of shapes. RNA has the bases adenine, cytosine, guanine, and uracil. The molecules also differ in their functions.

What are the structural differences between RNA and DNA quizlet?

Terms in this set (8) The three main differences between RNA and DNA is that (1) The sugar in RNA is ribose instead of deoxyribose, (2) RNA is generally single-stranded and not double-stranded , and (3) RNA contain uracil in place of thymine.

What are the important structural and functional differences between DNA and RNA?

DNA has a double helix structure. RNA has a single helix structure. The nitrogenous bases present in DNA are Adenine, Guanine, Thymine, and Cytosine. The nitrogenous bases present in RNA are Adenine, Guanine, Uracil, and Cytosine.

What are the 10 differences between DNA and RNA?

Summary of Differences Between DNA and RNA DNA contains the sugar deoxyribose, while RNA contains the sugar ribose. DNA is a double-stranded molecule, while RNA is a single-stranded molecule. DNA is stable under alkaline conditions, while RNA is not stable. DNA and RNA perform different functions in humans.

What are the 4 differences between DNA and RNA quizlet?

How is RNA different from DNA? RNA is different from DNA is three ways: (1) the sugar in RNA is ribose not dioxyribose; (2) RNA is generally single-stranded and not double-stranded; and (3) RNA contains uracil in place of thymine. Why are the chemical differences between RNA and DNA important?

Which of the following structural features is common between DNA and RNA?

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).

What is the structure RNA?

RNA consists of ribose nucleotides (nitrogenous bases appended to a ribose sugar) attached by phosphodiester bonds, forming strands of varying lengths. The nitrogenous bases in RNA are adenine, guanine, cytosine, and uracil, which replaces thymine in DNA.

What are the structural difference between DNA and RNA Class 12 chemistry?

DNA	RNA
1.	The sugar moiety in DNA molecules is a deoxyribose.	The sugar moiety in RNA molecules is a ribose.
3.	The helical structure of DNA is double-stranded and narrower.	The helical structure of RNA is single-stranded and wider than DNA.
