RNA | MCQs

Explanation

Explanation

RNA contains Uracil instead of Thymine, which is found in DNA.

The four bases in RNA are Adenine (A), Uracil (U), Guanine (G), and Cytosine (C).

Explanation

Cytosine is found in both DNA and RNA, but uracil is unique to RNA.

In RNA, uracil replaces thymine, pairing with adenine during transcription.

Explanation

 Nucleic acids are composed of nucleotides.

NTPs (Nucleoside Triphosphates) are a type of nucleotide.

They consist of a nitrogenous base, a pentose sugar (ribose in RNA or deoxyribose in DNA), and three phosphate groups

Nucleic acids like DNA and RNA are built from chains of these nucleotides. 

Explanation

 An anticodon is located on tRNA (transfer RNA).

The anticodon is a sequence of three nucleotides that recognizes and binds to a specific codon on mRNA during protein synthesis. 

Explanation

Poxviruses are DNA viruses, while poliovirus, measles, and mumps are all RNA viruses. 

Explanation

The nucleotide found only in RNA is uracil (U).

While RNA and DNA share adenine (A), cytosine (C), and guanine (G), RNA utilizes uracil in place of thymine (T), which is found in DNA. 

Explanation

 In bacterial cells, RNA makes up about 6% of the total cell weight, which is relatively high compared to DNA due to the abundance of ribosomal RNA (rRNA).
