Which of the following DNA strands is complementary to the DNA sequence 5 Gattacagg 3?
Which of the following DNA strands is complementary to the DNA sequence 5 Gattacagg 3?
For the sequence 5′-GATTACA-3′, the complementary DNA strand would be 3′-CTAATGT-5′.
When sequences of base pairs are copied incorrectly they are called _______?
Genes & DNA – How DNA works
| Question | Answer |
|---|---|
| What is it called when scientists transfer genes from one organism to another? | genetic engineering |
| What are sequences of base pairs that are copied incorrectly called? | mutations |
| What is an example of chemical mutagens? | asbestos and chemicals found in cigarette smoke |
Which best expresses the relationship between genes and DNA?
gene. Which best expresses the relationship between genes and DNA? Nucleotides.
What are the subunits of DNA called?
Each chain is made up of repeating subunits called nucleotides that are held together by chemical bonds. There are four different types of nucleotides in DNA, and they differ from one another by the type of base that is present: adenine (A), thymine (T), guanine (G), and cytosine (C).
What is the relationship between DNA genes and chromosomes?
Genes are segments of deoxyribonucleic acid (DNA) that contain the code for a specific protein that functions in one or more types of cells in the body. Chromosomes are structures within cells that contain a person’s genes.
What are the 5 differences between DNA and RNA?
DNA contains the sugar deoxyribose, while RNA contains the sugar ribose. DNA and RNA base pairing is slightly different since DNA uses the bases adenine, thymine, cytosine, and guanine; RNA uses adenine, uracil, cytosine, and guanine. Uracil differs from thymine in that it lacks a methyl group on its ring.
What are the similarities and differences of DNA and RNA?
Both DNA and RNA have four nitrogenous bases each—three of which they share (Cytosine, Adenine, and Guanine) and one that differs between the two (RNA has Uracil while DNA has Thymine).
What are the similarities and differences between DNA and RNA quizlet?
Terms in this set (16)
- Both are polymers.
- Both use polymerase.
- Both have the bases adenine guanine and cytosine.
- Have nucleotides.
- Store information to build proteins.
How does RNA and DNA work together?
The two main types of nucleic acids are DNA and RNA. Both DNA and RNA are made from nucleotides, each containing a five-carbon sugar backbone, a phosphate group, and a nitrogen base. DNA provides the code for the cell’s activities, while RNA converts that code into proteins to carry out cellular functions.
Why is DNA structure more stable than RNA?
Due to its deoxyribose sugar, which contains one less oxygen-containing hydroxyl group, DNA is a more stable molecule than RNA, which is useful for a molecule which has the task of keeping genetic information safe. RNA, containing a ribose sugar, is more reactive than DNA and is not stable in alkaline conditions.
How do you determine DNA sequence from RNA?
DNA utilizes four bases, adenine (A), guanine (G), cytosine (C), and thymine (T), in its code. RNA also uses four bases. However, instead of using ‘T’ as DNA does, it uses uracil (U). Therefore, if your DNA sequence is 3′ T C G T T C A G T 5′, the mRNA sequence would be 5′ A G C A A G U C A 3′.
What is the relationship between DNA RNA and protein?
DNA, RNA, and protein are all closely related. DNA contains the information necessary for encoding proteins, although it does not produce proteins directly. RNA carries the information from the DNA and transforms that information into proteins that perform most cellular functions.
Does DNA control the production of protein?
The information to make proteins is stored in an organism’s DNA. Each protein is coded for by a specific section of DNA called a gene. A gene is the section of DNA required to produce one protein.
Which is the best description for how DNA RNA and protein are related?
Which is the best description for how DNA, RNA, and protein are related? DNA makes RNA, RNA makes proteins.
What is the relationship between DNA and mRNA?
During transcription, the DNA of a gene serves as a template for complementary base-pairing, and an enzyme called RNA polymerase II catalyzes the formation of a pre-mRNA molecule, which is then processed to form mature mRNA (Figure 1).
How is genetic code stored in DNA?
The Genetic Code is stored on one of the two strands of a DNA molecules as a linear, non-overlapping sequence of the nitrogenous bases Adenine (A), Guanine (G), Cytosine (C) and Thymine (T). These are the “alphabet” of letters that are used to write the “code words”.
