Biology Keystone Module 2

Front

What is DNA transcription?

Back

DNA transcription is the process by which a segment of DNA is copied into RNA, specifically messenger RNA (mRNA), which carries the genetic information to the ribosome for protein synthesis.

Front

What is the role of ribosomal RNA (rRNA)?

Back

Ribosomal RNA (rRNA) is a type of RNA that, along with proteins, makes up the ribosome, the site of protein synthesis in the cell.

Front

What is the difference between DNA transcription and DNA translation?

Back

DNA transcription is the process of creating mRNA from DNA, while DNA translation is the process of synthesizing proteins from mRNA.

Front

What are homologous structures?

Back

Homologous structures are anatomical features in different species that share a common ancestry, even if they have different functions.

Front

What is an ecosystem?

Back

An ecosystem is a community of living organisms interacting with their physical environment, including both biotic and abiotic components.

Front

What is a frame-shift mutation?

Back

A frame-shift mutation is a genetic mutation caused by the insertion or deletion of nucleotides in a DNA sequence, which alters the reading frame of the genetic code.

Front

What is complementary base pairing in DNA?

Back

Complementary base pairing refers to the specific pairing of nitrogenous bases in DNA: adenine (A) pairs with thymine (T), and cytosine (C) pairs with guanine (G).

Front

What is the significance of the original DNA strands during replication?

Back

The original DNA strands serve as templates for the synthesis of new complementary strands, ensuring that the genetic information is accurately copied.

Front

What is a population in biological terms?

Back

A population is a group of individuals of the same species that live in a specific area and can interbreed.

Front

What is the function of messenger RNA (mRNA)?

Back

Messenger RNA (mRNA) serves as a template for protein synthesis, carrying the genetic information from DNA to the ribosome.
