Question 1

a) Creation of two variables

DNA1= "CGTGA"
DNA2= "AGCTTCCA"

b) Concatenation of two variables

merge_DNA= paste(DNA1, DNA2, sep="")
print(merge_DNA)

[1] "CGTGAAGCTTCCA"

c) Creation of Substring

substr_DNA1= substr(DNA1, 2, 5)
print(substr_DNA1)

[1] "GTGA"

Question 2

Arithmetic operation of these variables

int1= 23
int2= 47
sum_int= int1+ int2
print(sum_int)

[1] 70

Sub_int= int1-int2
print(Sub_int)

[1] -24

Mul_int= int1*int2
print(Mul_int)

[1] 1081

Div_int= int1/int2
print(Div_int)

[1] 0.4893617

Power_int= int1^int2
print(Power_int)

[1] 1.002786e+64

Mod_int= int1%%int2
print(Mod_int)

[1] 23
