Question

1) Explain DNA And It's Structure
2) Explain RNA And Its Types​

Answer 1

Answer:

1.A molecule of DNA consists of two strands that form a double helix structure. ... The double helix looks like a twisted ladder—the rungs of the ladder are composed of pairs of nitrogenous bases (base pairs), and the sides of the ladder are made up of alternating sugar molecules and phosphate groups

2.Types and functions of RNA. 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. These and other types of RNAs primarily carry out biochemical reactions, similar to enzymes

Answer 2

Answer:

1) DNA (Deoxyribonucleic acid)is made up of molecules called nucleotides. Each nucleotide contains a phosphate group, a sugar group and a nitrogen base. The four types of nitrogen bases are adenine (A), thymine (T), guanine (G) and cytosine (C).

2) RNA is also a chain of nucleotides, but unlike DNA it is more often found in nature as a single-strand folded onto itself, rather than a paired double-strand. RNA is synthesized, from the template of DNA, with the help of an enzyme-RNA polymerase by a process known as transcription.
