DNA & GENETICS

What is DNA?

• protein that makes AMINO ACIDS

• nucleic acid that makes PROTEINS;

  the BLUEPRINT OF LIFE

• A segment of chromosomes

In DNA, what pairs with CYTOSINE?

• adenine

• guanine

• thymine

• adenine

What are the CORRECT DNA base pairs?

• ADENINE, THYMINE, CYTOSINE and GUANINE

• THYMINE, GUANINE, MELANINE and GUANINE

• ADENINE, THYMINE, NALINE and PHILOSOPHINE

Rosalind Franklin used x-ray diffraction to discover the shape of:

• messenger rNA

• the Punnett Square

• DNA

• tRNA

This is a SEGMENT of DNA which determines traits.

• a genotype

• an allele

• a phenotype

• a gene

Examples of PHENOTYPES include:

• red hair, blue eyes, curly hair, genes

• brown eyes, black hair, tall height, Hh

• blond hair, brown eyes, short height

• genotypes, hair color, traits and characteristics

PROCESS in which DNA makes a copy of ITSELF using enzymes.

• TRANSCRIPTION

• REPLICATION

• TRANSLATION

• MEIOSIS

Bb represents:

• a HOMOZYGOUS dominant combination

• a HETEROZYGOUS recessive combination

• a HETEROZYGOUS dominant combination

• a HOMOZYGOUS recessive combination

A chart used to determine all the possible outcomes of a genetic cross is called a(n):

• pedigree

• Hollywood square

• Punnett Cube

• Punnett Square

Cell division which results in daughter cells with HALF the usual number of chromosomes.

• mitosis

• conjunction

• meiosis
