Answer 6

Proteins are made of ribosomes.

Question 7

What is transcription

Answer 7

When DNA makes a copy of its self and sends a message called mRNA to the ribosomes

Question 12

Process that occurs during the cell cycle where DNA is copied or duplicated

Answer 12

DNA replication

Question 13

What is a nucleotide

Answer 13

A compound consisted of a nucleoside linked to a phosphate group

Question 14

Summarise the process of replication

Answer 14

Enzymes unzip the double helix

DNA polymerase makes a copy

Question 15

Summarise the process of transcription

Answer 15

mRNA sends a message to the ribosomes by linking the codon ontology ribosome
