Question

Which of the following molecules contains the genetic instructions for the amino acid sequences needed to build proteins?

1Points
A
DNA

B
rRNA

C
glucose

D
ATP

Answer 1

Answer: The correct answer is- A) DNA ( deoxyribonucleic acid).

DNA ( deoxyribonucleic acid) is considered as the genetic material of all life forms ( that is transferred from parents to next generation). It determines the particular protein that carry out various cellular processes essential for life as well as determine particular trait of the organism.

For this, DNA possesses genetic instructions in the form of specific nucleotide sequences ( codons that code for particular amino acid).

First, DNA undergoes transcription, in which genetic information is passed to mRNA ( messenger RNA), which is finally converted to specific protein with the help of process called translation.

Answer 2

Answer;

A. DNA

Explanation;

• DNA is a nucleic acids found in living organisms whose role is to store genetic information.
• DNA molecules encodes the sequences of amino acids residues in proteins using the genetic code. DNA provides the instructions for making of proteins in the cells. This occurs through the process of transcription and translation.
• The process of encoding the sequences of amino acids in proteins is also known as gene expression. That occurs through the process of transcription, where information is copied to an mRNA which is then translated to amino acids which joins to make proteins.
