#1
Front (Question)

Prokaryotic DNA

Back (Answer)

No nucleus Nucleoid DNA Single loop of DNA Short and circular May contain plasmids Non-linear Antibiotic resistance Virulence Not associated with proteins (histones)

#2
Front (Question)

Eukaryotic DNA

Back (Answer)

DNA arranged into long and linear chromosones DNA associated with histone proteins condensed into chromatin Compact Sex chromosomes and actosomes Can be found in mitochondria and chloroplasts contains introns

#3
Front (Question)

DNA in mitochondria and chloroplasts

Back (Answer)

Short Circular Not associated with proteins Similar to prokaryotic DNA Chloroplast DNA = cpDNA Mitochondria DNA = mtDNA

#4
Front (Question)

Allele

Back (Answer)

Alternative form of gene

#5
Front (Question)

Chromosone structure

Back (Answer)

One maternal one paternal Same genes but potentially different alleles

#6
Front (Question)

Gene

Back (Answer)

A base sequence of DNA that codes for the amino acid sequence of a whole polypeptide chain and function RNA which is crucial in protein synthesis

#7
Front (Question)

Homozygous alleles

Back (Answer)

The same alleles e.g F F

#8
Front (Question)

Heterozygous alleles

Back (Answer)

Different alleles e.g D d

#9
Front (Question)

Gene loci

Back (Answer)

Genes are always found at the same locus . The same gene occupies a fixed position on a particular DNA molecule. Loci named by chromosomal number, arm, region , band and sub-band
