Which statement describes one way that RNA differs from DNA quizlet?
Which statement describes one way RNA differs from DNA? They contain diffrent five-carbon sugars and a diffrent nitrogenous base.
What are the four ways that RNA differs from DNA quizlet?
Terms in this set (4)
- 1st difference. RNA is composed of a single strand of nucleotides, while DNA is a double strand.
- 2nd difference. RNA contains the sugar ribose, while DNA contains deoxyribose.
- 3rd difference. RNA contains uracil, while DNA contains thymine.
- 4th difference. RNA can leave the nucleus, while DNA cannot.
Which statement describes a structural difference between DNA and RNA?
So, the three main structural differences between RNA and DNA are as follows: RNA is single-stranded while DNA is double-stranded. RNA contains uracil while DNA contains thymine. RNA has the sugar ribose while DNA has the sugar deoxyribose.
Which macromolecule is the main source of energy for living things?
The four major groups of macromolecules found in living things are carbohydrates, lipids, nucleic acids, and proteins. Carbohydrates are compounds made up of carbon, hydrogen, and oxygen atoms, usually in a ratio of 1 : 2 : 1. Living things use carbohydrates as their main source of energy.
What are the 4 ways that RNA differs from DNA?
RNA differs from DNA in several ways: RNA is single-stranded, not double-stranded; unlike DNA polymerases, RNA polymerases are able to join RNA nucleotides together without requiring a preexisting strand of RNA; RNA has the base uracil in place of thymine, but like thymine, uracil can form hydrogen bond with adenine; …
What are four ways RNA differs from DNA?
List four ways in which the structure of RNA differs from that of DNA.
- DNA has the bases adenine, thymine, guanine, cytosine. RNA has the bases adenine, uracil, guanine, cytosine.
- DNA has sugar deoxiribose. RNA has sugar ribose.
- DNA is double stranded. RNA is single stranded.
- DNA can duplicate itself.
Which macromolecule has DNA and RNA as its examples?
Nucleic acids, macromolecules made out of units called nucleotides, come in two naturally occurring varieties: deoxyribonucleic acid (DNA) and ribonucleic acid (RNA).
Why do macromolecules differ in the amount of energy they contain?
1. B. Why do macromolecules differ in the amount of energy they contain? The amount of energy stored in macromolecules varies because their chemical structures, and therefore the energy contained in their chemical bonds, differ.
What are RNA and DNA examples of?
Two examples of nucleic acids include deoxyribonucleic acid (better known as DNA) and ribonucleic acid (better known as RNA). These molecules are composed of long strands of nucleotides held together by covalent bonds. Nucleic acids can be found within the nucleus and cytoplasm of our cells.
What are the 5 differences between DNA and RNA?
Which of the following is characteristic of RNA but not DNA?
RNA differs from DNA in that it is single stranded, has uracil instead of thymine, carries the code for making proteins instead of directing all of the cell ‘s functions, and has ribose as its five-carbon sugar instead of deoxyribose.
Why is RNA different in DNA in terms of nitrogenous bases?
DNA and RNA are different from their structure, functions, and stabilities. DNA has four nitrogen bases adenine, thymine, cytosine, and guanine and for RNA instead of thymine, it has uracil. Also, DNA is double-stranded and RNA is single-stranded which is why RNA can leave the nucleus and DNA can’t.
What is the difference between DNA and RNA quizlet?
RNA is different than DNA because it has: ribose for the sugar, uracil instead of thymine, and it is single-stranded. DNA is different than RNA because it has: deoxyribose for the sugar, thymine instead of uracil, and it is double stranded.
What is the difference between the function of DNA and RNA?
DNA provides the code for the cell’s activities, while RNA converts that code into proteins to carry out cellular functions. The sequence of nitrogen bases (A, T, C, G) in DNA is what forms an organism’s traits.
What is the difference between RNA and mRNA?
The main difference between RNA and mRNA is that RNA is the product of the transcription of genes in the genome whereas mRNA is the processed product of RNA during post transcriptional modifications and serves as the template to produce a particular amino acid sequence during translation in ribosomes.
Which of the following is not a difference between RNA and DNA?
The correct answer is: (c) DNA contains alternating sugar-phosphate molecules whereas RNA does not contain sugars.
In which ways is RNA different from DNA select three properties that apply to RNA but not DNA?
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. 1b) List the three main types of RNA, and explain what they do.
What is the difference between DNA RNA and mRNA?
A single molecule of DNA can also be very long. RNA on the other hand, are single stranded polymers that are much shorter. mRNA is a straight chain molecule, whereas tRNA folds back onto itself forming three hairpin loops, making the overall molecule a “three leaf clover” shape.
