Question

In which of the following ways are DNA and mRNA similar?

Answer 1

They are both always kept in the nucleus to keep them safe from damage.

They are both double stranded and must be unzipped during replication and transcription.

They both contain the entire genetic sequence of the original DNA from their parent cell.

They both copy genetic code by forming a complementary sequence of nucleotides with an existing strand of DNA.

Answer 2

really need help on this one

Answer 3

They are composed of similar materials: DNA is a deoxyribonucleotide polymer while RNA is a ribonucleotide polymer. A nucleotide is composed of a nitrogenous base, a sugar, and a phosphate group. In ribonucleotides, the sugar is ribose, while in deoxynucleotides, the sugar is deoxyribose. Adenine, guanine, and cytosine are nitrogenous bases in both DNA and RNA, while thymine is found only in DNA and uracil is found only in RNA.

Answer 4

so its c ?

Answer 5

what would you say?

Answer 6

@bigtrell97 RNA is definitely not always in the nucleus, and for that matter, DNA is not always found in the nucleus. Bacteria and Archaea have no nucleus. Single stranded DNA and RNA exist in biological systems. RNA is derived from portions of DNA (genes).

Answer 7

i think its either c or d im really confused on this one

Answer 8

@bigtrell97 Read my last sentences and you can sort C and D out.

Answer 9

thank you
