Front

What are the complementary RNA bases for DNA bases T, A, and C?

Back

The complementary RNA bases are A, U, and G.

Front

What are the two key characteristics of DNA replication?

Back

1. It occurs during interphase. 2. It is semi-conservative.

Front

What is the base sequence of mRNA transcribed from the DNA sequence ACC GTG CAG GAT?

Back

The mRNA sequence is UGG CAC GUC CUA.

Front

In which types of molecules can the nucleotide sequence GGACAGAGCGCAGACGA be found?

Back

This sequence can be found in both DNA and RNA molecules.

Front

What does adenine pair with in RNA during transcription?

Back

Adenine pairs with uracil in RNA.

Front

Define DNA replication.

Back

DNA replication is the process by which a cell makes an exact copy of its DNA before cell division.

Front

What is the role of mRNA in protein synthesis?

Back

mRNA carries the genetic information from DNA to the ribosome, where proteins are synthesized.

Front

What is the difference between DNA and RNA?

Back

DNA is double-stranded and contains thymine, while RNA is single-stranded and contains uracil.

Front

What is the significance of the semi-conservative model of DNA replication?

Back

In the semi-conservative model, each new DNA molecule consists of one old strand and one new strand, ensuring genetic continuity.

Front

What are the four bases found in DNA?

Back

The four bases in DNA are adenine (A), thymine (T), cytosine (C), and guanine (G).
