Question 2

What are the types of Prokaryotic Cell

Answer 2

Bacteria and Archaea

Question 3

Difference between Eukaryotic and Prokaryotic Cells

Answer 3

Eukaryotic cells contain membrane-bound organelle

Question 4

What Structure contains genetic information in a cell

Answer 4

Chromosomes

Question 5

a chromosome contains

Answer 5

One very long DNA molecule with hundreds or thousands of genes

Question 6

What is a DNA molecule made up of

Answer 6

2 long strands, or chains, arranged in a double helix.

Question 7

What is one strand of the DNA molecule made up of

Answer 7

4 types of Nucleotides, abbreviated as A,T,C, and G

Question 8

The Sequence of these nucleotides do what

Answer 8

Encode different information into our genes

Question 9

For a lot of genes, what does the sequence of nucleotides do.

Answer 9

Blueprint for making a protein

Question 10

Protein-encoding genes control the production of proteins by working through an intermediary molecule called

Answer 10

RNA

Question 11

Describe Transcription

Answer 11

First step of the protein production sequence, where the sequence of Nucleotides is copied to produce a molecule called RNA.

Question 12

Why does the cell have to create RNA

Answer 12

To transmit the Nucleotide sequence outside of the Nucleus

Question 13

Describe Translation

Answer 13

Second step of the protein production sequence, where the RNA is transported to the Ribosome, where it is translated into a protein.

Question 14

During Translation, Nucleotides are read in sets of

Answer 14

3

Question 15

What is a set of 3 Nucleotides also called

Answer 15

A codon

Question 16

During Translation, what is first thing produced by the ribosomes

Answer 16

The ribosome assembles amino acids in the order specified by the RNA and then linking them to form an amino acid chain.

Question 17

Chain of Amino Acids is called

Answer 17

Polypeptide

Question 18

A specific sequence of nucleotides in one organism will

Answer 18

code for the same proteins in another organism

Question 19

What is a Genome

Answer 19

The complete set of DNA in an organism

Question 20

Energy does what through an ecosystem

Answer 20

Goes through the ecosystem in one direction, usually entering as sunlight and exiting as heat

Question 21

Chemicals do what in an ecosystem

Answer 21

Chemicals Cycle in an ecosystem

Question 22

3 domains of life

Answer 22

Archaea, Bacteria, Eukarya
