Answer 3

Process of determining the complete sequence of nucleotides within a segment of DNA

Question 4

Stem cell

Answer 4

An un specialized cell that can reproduce in definitely and differentiate into specialized cells of one or more types

Question 5

Gene annotation

Answer 5

Analysis of genome sequence is to identify protein coding genes that determine the function of their products

Question 6

Proteomics

Answer 6

Studying for protein sets encoded by genomes

Question 7

Pseudogens

Answer 7

You need non-coding DNA that was once a gene that has accumulated mutations over a long period of time and no longer produces functional proteins

Transposable elements

Answer 8

Segment of DNA that can move from one location to another within the genome during the process called transposition

Transposons: cut paste
Retransposons: copy paste

Question 11

Transposon

Answer 11

Transposable elements that moves within the genome by means of a DNA intermediate
