LT 2.1: Genetics_Structure and Function

Front

What is the structure of DNA?

Back

DNA is structured as a double helix, which consists of two strands twisted around each other.

Front

What contains the genetic material in a cell?

Back

The nucleus contains the genetic material (DNA) in a cell.

Front

How do genes influence traits in an organism?

Back

Genes influence traits by coding for specific proteins that determine the characteristics of an organism.

Front

What is a nucleotide?

Back

A nucleotide is the basic building block of DNA and RNA, consisting of a phosphate group, a sugar, and a nitrogenous base.

Front

What part of the nucleotide is labeled 'C'?

Back

The part labeled 'C' is the nitrogenous base.

Front

What part of the nucleotide is labeled 'B'?

Back

The part labeled 'B' is the sugar (deoxyribose in DNA or ribose in RNA).

Front

What are the four nitrogenous bases in DNA?

Back

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

Front

What is the function of ribosomes in a cell?

Back

Ribosomes are responsible for protein synthesis by translating messenger RNA (mRNA) into polypeptides.

Front

What is the role of the mitochondria?

Back

Mitochondria are known as the powerhouse of the cell, generating ATP through cellular respiration.

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.
