CFA NEED 2 KNOW

Question 1

What’s Transcription process?

Answer 1

Transcription is the process of producing a strand of mRNA from a strand of DNA

Question 2

What’s Translation process?

Answer 2

Translation is the process through which information encoded in messenger RNA (mRNA) directs the addition of amino acids during protein synthesis.

Question 3

How do we get to DNA to an actual model protein?

Answer 3

Transcription & Translation

Question 4

What’s the location of Transcription occurs?

Answer 4

nucleus

Question 5

What’s DNA role in Transcription?

Answer 5

To make a complimentary copy of strand of itself.

Question 6

What’s mRNA’s role in Transcription?

Answer 6

mRNA is to carry the protein information to the cytoplasm.

Question 7

What’s the location of Translation?

Answer 7

Cytoplasm

Question 8

What is codon and their roles?

Answer 8

The codon roles are to code for a specific amino acids to create a protein.

Question 9

What are anticodons and their role?

Answer 9

The anti-codon allows the tRNA to bring the correct amino acids in a line with an mRNA.

Question 10

What’s mRNA role in translation?

Answer 10

Carry protein information
The role of mRNA in translation is to carry protein information from the DNA in a cell’s nucleus to the cell’s cytoplasm.

Question 11

What’s tRNA role in Translation?

Answer 11

carry amino acids to the ribosome and match them with the codons in the mRNA strand.

Question 12

What’s rRNA role in Translation?

Answer 12

rRNA role is to read and match the codons with tRNA anti-codons that codes for the amino acids that create a protein.

Question 13

What’s the Amino Acids role in Translation?

Answer 13

To Code for the Proteins

Question 14

What does mRNA stand for?

Answer 14

Messager RNA

Question 15

What does tRNA stand for?

Answer 15

tranferr RNA

Question 16

What does rRNA stand for?

Answer 16

ribosomes RNA

Question 17

In a strand of RNA, the A’s will become..

Answer 17

U’s

Question 18

What’s the anticodon from tRNA.

Answer 18

The complementary condon

Question 19

Process of Natural selection

Answer 19

The process of who dies and who lives (Survival of the fittest)

Question 20

How do species have mutations are genetic variation?

Answer 20

Its random, Organisms have random mutation and genetic variation because of sexual reproduction.

Question 21

Are all mutations and genetic variation good?

Answer 21

Some mutations are good, some do nothing, and some are bad (all random)

Question 22

Do species adapt to the environment to change?

Answer 22

No, they don’t “adapt” because it’s not optional for them. However, a random mutation by accident.

Question 23

What are environmental factors?

Answer 23

Environmental Factors are the factors that determine what traits will survive or die off.

Question 24

Can environment factors change?

Answer 24

Yes, environmental factors can change randomly.

Question 25

A specie with genetic variation or without are most likely to survive?

Answer 25

A species with genetic variation is most likely to survive because the different traits might help them survive.

Question 26

What is genetic drift?

Answer 26

Genetic Drift is a change in allele frequencies that is due to random chance.

Question 27

How does genetic drift happens?

Answer 27

It happens randomly

Question 28

Are genetic and Natural selection the same thing?

Answer 28

No, the different between is that natural selection isn’t due to a chance its due to better traits surviving.

Question 29

What type of Genetic Drifts are they?

Answer 29

1. Bottleneck Effect
2. Founder Effect

Question 30

What is bottleneck effect of genetic drift?

Answer 30

A population drastically dies out due to something (for a least one generation) some alleles die out some survive, the surviving continues to grow. ALL RANDOM

Question 31

What is founder effect in genetic drift?

Answer 31

small part of population breaks off, moves away, and establish its own population. which alleles that move away its completely random. Which it results in a new population of species

Question 32

What is speciation?

Answer 32

speciation is the process of species becoming a different species or when an organism branches off and becomes another species.

Question 33

What is the reason for genetic drift?

Answer 33

reproductive isolation

Question 34

What are the 3 reproductive isolations?

Answer 34

1. behavioral
2. temporal
3. Habitat

Question 35

What is behavioral in reproduction isolation?

Answer 35

Behavioral reproduction isolation is species not mating because of differences in behaviors

Question 36

What is temporal isolation?

Answer 36

When species don’t mate due to differences in timing

Question 37

What is habitat isolation?

Answer 37

When species dont mate due to bring in different habitats

Question 38

What’s Endosymbiont Theory?

Answer 38

The organelles in eukaryotic cell used to be their own cell until they were eaten by other prokaryotic.

Question 39

What three reason that prove the theory of endosymbiont is correct.

Answer 39

1. Both have cell membrane
2. Have DNA/genetics
3. asexual reproduction

Question 40

New traits are always caused by …

Answer 40

Mutation

Question 41

If genes have variation there are two ways for allele frequencies/number (the amount of the trait) to be to decrease or increase

Answer 41

Natural selection (alleles change based on survival)
AND genetic drift

Question 42

Alleles in other words are…

Question 43

Mutations just causes the traits (TRUE or FALSE)

Answer 43

TRUE

Question 44

Natural Selection is…

Answer 44

alleles/traits changing based on advantage or disadvantage. This is a selection.
