what is dna

the gene is a unit of function that controls the synthesis of at least one polypeptide chain (protein)or RNA molecule.
Hereditary factors responsible for traits

2

what is a chromosome

genes are located on chromosomes, they contain proteins and nucleic acid, the nucleic acid are DNA and RNA

3

what is rna

...

4

what is protein

...

5

what are prions

are inheritable infectious proteins that do not contain nucleic acid

6

prokaryotic gene

...

7

eukaryotic gene

...

8

difference between prokaryotic gene and eukaryotic gene?

...

9

3 functions of genetic function

replication, expression, mutation

10

where in the cell is the genetic information kept

the nucleus

11

a recessive trait is one that

is masked by a dominant trait, if a dominant trait is present in the genotype

12

a dominant trait is one that

will always be expressed if it is present in the genotype

13

different forms of genes are known as

alleles

14

the building blocks of genes are

nucleic acids

15

the heritable factors that mendel studied are now known as

genes

16

nucleic acids are composed of a series of

nucleotides

17

which best describes the flow of information in a biological system

dna - rna - protein

18

changes that are introduced in the dna strand during replication are known as

mutations

19

information from DNA is transferred to RNA molecules during which process

transcription

20

information from RNA molecules are transferred to proteins during which process

translation

21

transcription stages

initiation, elongation, termination
