DNA

Question 1

DNA Full Name

Answer 1

Deoxyribonucleic Acid

Question 2

DNA

Answer 2

An information molecule that is the universal basis of an organism’s genetic material, written in a chemical code for the production of proteins by the cell

Question 3

Epigenetic Factors

Answer 3

A chemical tag that determines the degree of coiling of the DNA around the nucleosome and thus gene expression

Question 4

Genes

Answer 4

A region of DNA, made up of nucleotides, that codes for a specific polypeptides

Question 5

DNA in Prokaryotes

Answer 5

DNA is stored in small circular molecules that are freely suspended in the cytoplasm. The chromosome can be found in a distinct region of the cell called a nucleoid

Question 6

Plasmids

Answer 6

Small circular pieces of DNA, which can replicate independently of the cell’s chromosome; carry antibiotic resistance

Question 7

DNA in Eukaryotes

Answer 7

The DNA is present in chromosomes that are linear pairs (diploids) and arises through sexual reproduction. One chromosome from each pair comes from the male parent via the sperm and the other from the female parent via the ovum; when the two pairs of chromosomes are combined (fertilisation), a zygote is formed

Question 8

Karyotype

Answer 8

Displays the number and appearance of the chromosomes an organism has
