Describe the structure and components of a DNA molecule

Biology
1 answer:
Inessa [10]3 years ago
5 0
The DNA (deoxyribonucleic acid) is the double helical in structure. It has two anti parallel strands of long polynucleotides. The nucleotides are two purines ( adenine and guanine) and two pyrimidines ( thymine and cytosine). These purines and pyrimidines are attached with their complementary. Adenine pairs with the thymine with the two hydrogen bonds and the guanine pair with cytosine by three hydrogen bonds. The two strands are twisted which is responsible for the helical structure. The overall charge on the DNA molecule is the negative charge.

Examine the molecular model of the partial structure of the yeast atp synthase. which part of the molecule spans the inner mitoc
VLD [36.1K]

ATP synthase or Complex V spans the inner mitochondrial membrane. ATP synthase and respiratory chain are biochemically SEPARATE systems and they are linked only by PROTON MOTIVE FORCE. Proton motive force is generated by electron transport.

ATP synthase resembles a ball on a stick which locates in the inner mitochondrial membrane. The answer is FO rotor.

What are restriction enzymes and how are they used to cut DNA?
Colt1911 [192]

Answer and Explanation:

A restriction enzyme is a type of endonuclease enzyme  that recognizes  a specific short nucleotide sequences on the DNA and  cuts the DNA only at palindromic sites. There are different types of restriction enzymes:

1. Type I restriction enzyme – It cuts at sites far  from the recognition site and requires both ATP and S-adenosyl-  L-methionine as cofactor to function.  

2. Type II restriction enzymes – It cleaves at short-specific distances from the recognition  site and mostly  requires magnesium to function.

3. Type III restriction enzymes – It recognizes two  separate non-palindromic sites and cleaves at 20–30 base  pairs away from a recognition site. It requires both ATP  and S-adenosyl-L-methionine  .

The restriction enzymes cleave DNA sequences producing either sticky or blunt ends that can be ligated with other sequences.

If a Tt plant is crossed with a Tt plant, what is the chance that a tt offspring will be produced? 75% 25% 50% 100%
adoni [48]

Answer: the correct answer is 25%

T is the allele for tall plant, which is dominant trait. 't' is the allele for dwarf plant, which is a recessive trait.

Genotypes of the parent plants are- Tt and Tt. When they are crossed, there are 25% chances of producing tt offsprings. Refer the punnett square for this.

% of Offsprings with tt genotype = \frac{1}{4} \times 100

                                                      =  25%
