This kind of linkage is this called as 3-5?
Phosphodiester linkage

Gives the codes for proteins that make up almost any part of our body?
Gene

Copying of the DNA during mitosis in order for the daughter cells to have the same DNA is called?
Replication
15
is one of the theee essential macromolecules that is needed by living things.
RNA
16
RNA is made up of five carbon sugar called?
Ribose
17
What is the base of RNA is called?
Uracil base
18
RNA can also be found in the?
The Nucleus and cytoplasm of the cell
19
it is formed in the nucleoplasm with the use of a DNA template and has a group of three based called as?
Codons
20
What us mRNA
Messenger RNA
21
What is tRNA?
Transfer RNA
22
tRNA has three exposed bases called as?
Anticodons
23
Why DNA cannot go to cytoplasm?
Nucleus is enclosed by the nuclear membrane
24
What is rRNA?
Ribosomal RNA
25
is made in the nucleolus and forms important structural component of the ribosome.
rRNA
26
The transfer if codes from the DNA to become a protein is called?
Gene expression
27
Gene expression has two steps
Transcription and Translation
28
is the porcess in which the codes of the DNA are converted int the codes in the mRNA.
Transcription
29
To carry the code from DNA to the ribosomes where translation into protein occurs.
mRNA
30
To show a site of the DNA where you would see specific sequence of nucleotides called?
Nucleus
31
it contain the site for initiation of the transcription of genes.
Promoter
32
Transcription occurs in three stages
Initiation Elongation Termination
33
ovcurs when the DNA sequence that makes up a gene is altered.
Gene mutation
34
Where does gene mutation occur?
Nucleotide of the gene
35
are inherited from parents as they are present in the sperm cell and the egg cell.
Heredity mutations
36
are caused by failure of the DNA to replicate itself properly and by environmental factors such as exposers to harmful chemicals and ultraviolet radiation which cause the DNA to break down
Somatic Mutation
