Differences Between RNA and DNA & Types of RNA (mRNA, tRNA & rRNA)
Which of the following statements is true? Hydrogen bonds can form between bases in a single RNA molecule. cRNA is the copy created when DNA is transcribed into RNA. The Central Dogma states that DNA is the most important nucleic acid. tRNA transfers proteins to the cell membrane.
Hydrogen bonds can form between bases in a single RNA molecule.
Which of the following are reasons why RNA is generally less stable than DNA? I. Fewer hydrogen bonds II. Prevalence of proteins that can degrade RNA III. Fewer -OH groups in the sugar of RNA II and III I and II I, II and III I and III
I and II
Which of the following are ways in which RNA is different than DNA: I. Single-stranded II. Ribose III. Uracil I and III I, II and III II and III I and II
I, II, and III
Which of these statements isn't true? RNA is stable. DNA makes RNA, and RNA makes protein. Uracil is a nitrogenous base found in RNA, whereas DNA contains thymine. There are three types of RNA, including mRNA, rRNA, and tRNA.
RNA is stable.
Which of the following nitrogenous bases is NOT found in RNA? Cytosine Uracil Adenine Thymine
Thymine
what do fewer hydrogen bonds mean?
a less stable structure.
what is RNA?
a nucleic acid composed of a sugar, a phosphate group and a nitrogenous base
how can the information found in mRNA be interpreted?
by using two other forms of RNA in the second step of the central dogma.
mRNA
created when the DNA recipe is copied in the first step of the central dogma
why is DNA more stable than RNA?
due to its many hydrogen bonds
tRNA
ferry amino acids to the ribosome to be assembled into proteins
Uracil
forms two hydrogen bonds with adenine and functions just like thymine does.
what are the four bases found in DNA?
guanine, cytosine, adenine, and thymine
what are the three major types of RNA?
mRNA, tRNA, rRNA
RNA
ribonucleic acid
what does the central dogma state?
states that DNA creates RNA and RNA makes protein
rRNA
that serve as structural components of protein-making structures known as ribosomes
what is one difference between DNA and RNA?
the sugar in DNA is deoxyribose, the sugar in RNA is ribose
