Question 0

Monomers

Answer 0

Single nucleotides

Question 1

Nucleotides

Answer 1

Monomers that consist of a 5 carbon monossaccharide (sugar), a phosphate group and a nitrogenous base

Question 2

RNa

Answer 2

Consists of a single strand of nucleotides

Question 3

DNA

Answer 3

Consists of 2 seperate chains of nucleotides connected by weak hydrogen bonds

Question 4

Complementary base pairing

Answer 4

A with t g with c

Question 5

Anti parallel

Answer 5

2 strands of dna are anti parallel go oppossite ways

Question 6

Purines and pyramidines

Answer 6

Purines: a,g bigger
Pyramidines: c t
Purine needs to be paired up with a puramidine

Question 7

Histones

Answer 7

Proteins allow dna to be supercoiled more dense takes up less space, nucleosome holds dna together, wraped around each nucleosome twice before moving to next one, genes cant be expressed, shown in metaphase

Question 8

Genes

Answer 8

Heritable factors that control specific characteristics

Question 9

Codon

Answer 9

3 bases that code for an amino acid

Question 10

Exons and introns

Answer 10

Exons coding region
Introns non coding regions edited out
Both are in a eukariotic gene

Question 11

Highly repetitive sequence

Answer 11

Makes up 5-45% of genome, was called junk dna and satellite dna, each repeated sequence can be from 5-300 pairs. Used in genetic fongerprinting, accumulate mutations rapidly

Question 12

Dna replication

Answer 12

Occurs during s phase of interphase,
