What else can I help you with?
The DNA language consists of a linear sequence of nucleotide?
Yes, the DNA language is composed of four nucleotide bases: adenine, cytosine, guanine, and thymine, arranged in a linear sequence along the DNA strand. This sequence carries genetic information that is transcribed and translated to produce proteins.
How does the DNA nucleotide sequence determine the amino acid sequence?
DNA sequence undergoes transcription, then translation process in order to determine and subsequently produce the amino acid sequence. The four bases specifically A,C,G, & T are the main coding sequence of a DNA. Because each coding sequence is unique, the resulting amino acid sequence is also unique as well.
Which of the following is a point mutation that does not produce a frame shift?
A point mutation that does not produce a frame shift is when one single base is replaced by a different base. This changes the DNA sequence, but does not cause a frame shift because it is a switch not an addition or subtraction of a base.
How do transciption and translation change information from one form to another?
From nucleic acids to amino acids. Transcription copies the nucleotide sequence of DNA into RNA; in translation ribosomes recreate the messenger-RNA pattern into a copy of the sequence.
What amino acid would be produced if transcription took place from the DNA sequence CAT?
Transcription of the DNA sequence CAT would produce the messenger RNA sequence CAU. This mRNA sequence would then be translated by ribosomes to produce the amino acid histidine.

What are the four ingredients added to a test tube to produce tagged DNA fragment that can be used to read a sequence of DNA?
The four nucleotide bases A, T, G, and C.
Why did steps 3 and 4 produce different polypeptides?
Steps 3 and 4 likely produced different polypeptides due to differences in the nucleotide sequence of the mRNA that was used as the template for protein synthesis. The codons in mRNA determine the sequence of amino acids in the polypeptide chain. Any change in the nucleotide sequence can lead to the incorporation of different amino acids during translation, resulting in a different polypeptide being produced.

Genetic engineering refers to the process of?
Genetic engineering is a lab technique used by scientists to change DNA of living organisms. It involves taking DNA from one organism and putting it into an unrelated organism (bacteria gene into corn, for example) in order to produce a desired trait.
Is amniocentesis a technique used to produce an image of the fetus?
No, ultrasound is a technique used to produce an image of the fetus.
What amino acid wuld be produced of transcrition takes place from a nucleotide with the three-base sequence ATA?
Tyrosine. If ATA is the DNA codon, the mRNA transcription would be UAU (since A pairs with U in RNA rather than T). UAU codes for tyrosine.
Which of the following is a point mutation that does not produce a frame shift?
A point mutation that does not produce a frame shift is when one single base is replaced by a different base. This changes the DNA sequence, but does not cause a frame shift because it is a switch not an addition or subtraction of a base.
What enables DNA to be copied?
Before a cell divides, its DNA is replicated (duplicated.) Because the two strands of a DNA molecule have complementary base pairs, the nucleotide sequence of each strand automatically supplies the information needed to produce its partner.
What is the copying of the DNA called?
The process by which a double-stranded DNA molecule is copied to produce two identical DNA molecules is called replication. The two strands of a DNA molecules have complementary base pairs, and so the nucleotide sequence of each strand automatically gives the information needed to produce its partner.
How do transciption and translation change information from one form to another?
From nucleic acids to amino acids. Transcription copies the nucleotide sequence of DNA into RNA; in translation ribosomes recreate the messenger-RNA pattern into a copy of the sequence.

Transcription of the DNA sequence CAT would produce the messenger RNA sequence CAU. This mRNA sequence would then be translated by ribosomes to produce the amino acid histidine.
