What are the subunits of nucleic acids?
Nucleic acids are composed of smaller subunits called nucleotides. A nucleotide is a nucleoside with one or more phosphoryl group by esterlinkage. When it is in the form of RNA the bases are called adenylate, guanylate, cytidylate, and uridylate.
What 3 things make up nucleic acids?
Structure of Nucleic Acids A nucleotide is made up of three components: a nitrogenous base, a pentose sugar, and a phosphate group.
Which term means subunit that makes up nucleic acids?
Nucleic Acids. Polymers assembled from individual nucleotides; used to store and transmit hereditary, or genetic, information; the two kinds of nucleic acids are ribonucleic acid (RNA) and deoxyribonucleic acid (DNA) (p.
Where are nucleic acid found in the body?
Is RNA present in human body?
RNA has been found in a panoply of human body fluids: blood, urine, tears, cerebrospinal fluid, breast milk, amniotic fluid, seminal fluid and others.
What are the 3 RNA types?
Of the many types of RNA, the three most well-known and most commonly studied are messenger RNA (mRNA), transfer RNA (tRNA), and ribosomal RNA (rRNA), which are present in all organisms.
Is RNA positively or negatively charged?
Double- and single-stranded DNA and RNA are all strongly negatively charged, with sub-nanometer inter-phosphate charge separations.
What gives DNA negative charge?
The phosphate backbone of DNA is negatively charged due to the bonds created between the phosphorous atoms and the oxygen atoms. Each phosphate group contains one negatively charged oxygen atom, therefore the entire strand of DNA is negatively charged due to repeated phosphate groups.
What is the charge of virus?
All viruses adsorbed exclusively to negatively charged silica at pH values below their isoelectric points, i.e., under conditions favoring a positive surface charge on the virions.
