Genetics and DNA

Front

What is the role of mRNA in protein synthesis?

Back

mRNA (messenger RNA) carries the genetic information from DNA to the ribosome, where it serves as a template for protein synthesis.

Front

What is the function of DNA during the S stage of interphase?

Back

During the S stage of interphase, DNA is replicated to ensure that each daughter cell receives an identical set of chromosomes.

Front

What are the base pairing rules in DNA?

Back

In DNA, adenine (A) pairs with thymine (T), and cytosine (C) pairs with guanine (G).

Front

What is the structure of DNA?

Back

DNA is a double helix composed of two strands of nucleotides, with a sugar-phosphate backbone and nitrogenous bases paired in the center.

Front

What is a eukaryotic cell?

Back

A eukaryotic cell is a type of cell that has a nucleus and membrane-bound organelles, unlike prokaryotic cells.

Front

What is the significance of the y-intercept in a linear equation?

Back

The y-intercept is the point where the line crosses the y-axis, representing the value of y when x is zero.

Front

What is transcription in the context of genetics?

Back

Transcription is the process by which the information in a gene is copied into mRNA.

Front

What is translation in the context of genetics?

Back

Translation is the process by which ribosomes read mRNA and synthesize proteins based on the sequence of codons.

Front

What are codons?

Back

Codons are sequences of three nucleotides in mRNA that correspond to specific amino acids or stop signals during protein synthesis.

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 instead of thymine.
