Match the following.

1 . adenine a nitrogen base occurring in dna and rna;
2 . deoxyribose first leaf or leaves
3 . guanine a nitrogen base found in dna or rna;
4 . cytosine
5 . dna a giant molecule consisting of the sugar deoxyribose,
6 . cotyledons a nitrogen base found in dna and rna;

a. pairs normally with thymine
b. produced from the seed
c. pairs normally with guanine
d. a five-carbon sugar
e. phosphates and nitrogen bases
f. normally pairs with cytosine

1. Adenine

2. Cotyledons

3. Cytosine

4. DNA

5. Guanine

Explanation:

1. A nitrogen base occuring in DNA and RNA; pairs normally with thymine is Adenine.

According to Watson and Crick, purine bases always pair with pyrimindine bases. Hence, Adenine always pair with Thymine and Guanine always pair with cytosine.

2. First leaf of leaves produced from seed is cotyledons. When it is one, the plant is a monocot, if two, the plant is a dicot.

3. A nitrogen base found in DNA or RNA; pairs normally with guanine is cytosine.

4. A giant molecule consisting of the sugar deoxyribose, phosphates and nitrogen bases is a DNA.

5. A nitrogen base found in DNA and RNA; normally pairs with cytosine is guanine.

the correct answer is: d. the saltine and pretzel are made of flour, yeast, and baking soda, and salt. the pecan contains no flour but it does contain fats. the pecan is a nut that can be consumed as a healthy snack. first of all, pecans are a source of fat (monounsaturated fat), but they provide less fat than some other nuts. pecans are a rich source of dietary fiber, manganese magnesium, phosphorus, thiamin, vitamin e…
