Write a program whose input is a DNA sequence (a string), and whose output indicates the number of times the nucleotide base 'g' is found in the sequence. Ex: If the input is:
agtctstcgtatgg

the output is:
4

Ex: If the input is:
gctgcgtttgggtagt

the output is:
7

in python:

dna = (whatever the DNA sequence is)

print(dna.count('g'))

I hope this helps!

answer6-9 screws;

only #2 represents an object at rest on a table.

in #1, there is no normal force due to the table; the object is accelerating downward.

in #3, the vertical forces are not balanced; the object is accelerating downward.

in #4, neither the vertical nor the horizontal forces are balanced. the object is accelerating upwards and to the right.
