DNA & Intro to Human Systems

A, T, C, G make up the code for DNA

• Nitrogenous base
• DNA
• Excretion
• Chromosomes

building blocks (subunits) of nucleic acids - has a phosphate group, sugar, and base

• Nucleotide
• Excretory System
• Nucleic acids
• Complimentary base

Chromosome pairs (1 from each parent) that have the same genes, but the genes may contain different alleles.

• Centromere
• Homeostasis
• Circulatory System
• Homologous chromosomes

different versions of a gene

• Allele
• Monomers
• Excretion
• Semiconservative

during replication of DNA, one strand of the new molecule of DNA comes directly from the original parent molecule of DNA

• Nervous System
• Semiconservative
• Chromatin
• DNA

Loosely coiled DNA (How DNA is usually found)

• Chromatin
• Chromosomes
• Replication
• Centromere

matching nitrogen base on a strand of a nucleic acid

• Semiconservative
• Homeostasis
• Complimentary base
• Excretion

nucleic acid that has the directions for making proteins

• Nucleic acids
• Respiratory System
• DNA
• Nervous System

Organelle that holds the DNA

• Excretory System
• Nucleic acids
• Nucleus
• Sister chromatids

organic molecules carry genetic information, made of nucleotides

• Nucleotide
• Homeostasis
• Nucleic acids
• Nucleus
