DNA molecules consist of chemically linked sequences of the bases adenine, guanine, cytosine, and thymine, denoted A, G, C, and

T. A sequence of three bases is called a codon. A base may appear more than once in a codon. How many different codons are there?

Answer: 64 codons

Explanation:

The triplet nature of the genetic code make for a possible 64 codons: 61 code for amino acids present in most polypeptide chains while the remaining 3 are special-sense codons, since they only signal for the termination of the polypeptide chain.

Thus, the pattern of the genetic code permits that a base appear more than once in a codon. For instance Adenine occurs twice in both AAU and AAC codons, which code for asparagine.

Match the mountain range with its formation. 1. Appalachian 2. North American Cordillera 3. Aleutian 4. Andes A. Two continents
melisa1 [442]

Appalachian: A. Two continents colliding.


The Appalachian mountain range is an ancient example of a collision between two continental plates. Both plates have low density and little subduction occurs between them.


North American Cordillera: B. Terrane accretion


These form when two continents that collided bonded so tight that it forms a permanent land mass. If the continents would pull away from each other, the terrane stays intact.


Aleutian plate: D. Oceanic convergence


This is a type of convergence where one plate subducts beneath another plate. Between the two, the older plate is usually the one that subducts because it is usually more dense.


Andes mountain range: C. An oceanic plate and continental plate colliding.


In the collision between an oceanic and continental plate, the thinner and more dense oceanic plate subducts under the continental plate. The Andes mountain range was formed by the subduction of the Nazca Plate beneath the South american Plate.

During sexual reproduction, two gametes merge to create a zygote that is a genetic mix of its two parents. For each statement, i
Elenna [48]

Answer:

1. 50% of the genome comes from each parent because it is crucial otherwise if the ratio changes, the zygote may not form and if formed the fetus may have some other kind of chromosome number related syndromes etc.

2.  Sexual reproduction produces greater genetic variability than asexual methods. This is because of the process of crossing over during meiosis that exchange the segments of chromosome that is necessary for producing mutations and genetic variability.

3. 50% of chromosomes match with each parent because both of the parents contributed 23 chromosomes and exactly 50% of their genome.

4. The gametes must be produced by two different individuals cause that is the main purpose of sexual reproduction and give better survival like this to the forming next generation. Not to mention produces greater genetic variability among species.

5. Plants always produces both eggs because they are hermaphroditic in nature.
