1.What is the genetic code? (1 point)

The order of amino acids in proteins makes up the genetic code.
The order of amino acids in mRNA makes up the genetic code.
The order of nitrogen bases in tRNA makes up the genetic code.
The order of nitrogen bases in DNA makes up the genetic code.

2. How do mRNA and tRNA work together to make proteins? (1 point)

tRNA carries the instructions coded in mRNA to the ribosomes where mRNA decodes DNA to make proteins.
mRNA carries the instructions coded in tRNA to the ribosomes where mRNA decodes DNA to make proteins.
mRNA carries the instructions coded in DNA to the ribosomes where tRNA decodes the mRNA to make proteins.
tRNA carries the instructions coded in DNA to the ribosomes where mRNA decodes the tRNA to make proteins.

I am lost on these two. Someone explain please? I really would like to ace this quiz !!

Thanks, yay

what are the answers

1. The correct answer to the first question is: "The order of nitrogen bases in DNA makes up the genetic code."

To understand this concept, it helps to have a basic understanding of genetics. In living organisms, genetic information is stored in molecules called DNA (deoxyribonucleic acid). DNA is made up of a sequence of four different nitrogenous bases: adenine (A), thymine (T), cytosine (C), and guanine (G).

The order, or sequence, of these bases in DNA determines the instructions for building proteins, which are essential for the functioning of cells. A protein is made up of a chain of amino acids, and the genetic code determines the specific sequence of amino acids that make up a protein.

So, in summary, the correct answer is the order of nitrogen bases in DNA makes up the genetic code because it determines the sequence of amino acids in proteins.

2. The correct answer to the second question is: "mRNA carries the instructions coded in DNA to the ribosomes where tRNA decodes the mRNA to make proteins."

To understand how mRNA and tRNA work together to make proteins, let's break it down step by step:

1. DNA in the nucleus of a cell contains the genetic code that specifies the sequence of amino acids in a protein. An enzyme called RNA polymerase helps to transcribe a specific portion of the DNA into a molecule called mRNA (messenger RNA).

2. mRNA carries the genetic instructions from the DNA to the ribosomes, which are the cellular structures responsible for protein synthesis. mRNA is made up of a sequence of three-nucleotide units called codons, where each codon specifies a specific amino acid.

3. As the mRNA passes through the ribosome, another type of RNA called tRNA (transfer RNA) brings the corresponding amino acids to the ribosome. tRNA molecules have an anticodon region that matches the codons on the mRNA sequence.

4. Each tRNA molecule carries a specific amino acid that matches its anticodon. When the anticodon of a tRNA molecule pairs with the codon on the mRNA, the ribosome links the amino acids together in the correct order, forming a protein chain.

So, in summary, mRNA carries the genetic instructions coded in DNA to the ribosomes, and tRNA helps to decode the mRNA sequence and bring the corresponding amino acids to build a protein.
