Amino acids are coded for by triplet bases in RNA called _____

Answers

Answer 1
Answer:

Amino acids are coded for by triplet bases in RNA called _Codon_.

  • These codons are a sequence of three nucleotide that forms a unit genomic information encoding for a particular amino acids.
  • There are 64 different codons:-        

                      -  61 specify amino acids

                      -   3 are used as stop signals

What is a codon?

  • A codon is a DNA or RNA sequence of three nucleotides that forms a unit of genomic information encoding a particular amino acid or signaling the termination of protein synthesis.
  • The nucleotides base pair that form codon are:

          -  Adenine

           - Guanine

           - Uracil

           - Cytosine

Answer 2
Answer: 1. Three nucleotides encode an amino acid. Proteins are built from a basic set of 20 amino acids, but there are only four bases. Simple calculations show that a minimum of three bases is required to encode at least 20 amino acids. Genetic experiments showed that an amino acid is in fact encoded by a group of three bases, or codon. 

2. The code is nonoverlapping. Consider a base sequence ABCDEF. In an overlapping code, ABC specifies the first amino acid, BCD the next, CDE the next, and so on. In a nonoverlapping code, ABC designates the first amino acid, DEF the second, and so forth. Genetics experiments again established the code to be nonoverlapping. 



3. The code has no punctuation. In principle, one base (denoted as Q) might serve as a “comma” between groups of three bases. 

This is not the case. Rather, the sequence of bases is read sequentially from a fixed starting point, without punctuation. 





4. The genetic code is degenerate. Some amino acids are encoded by more than one codon, inasmuch as there are 64 possible base triplets and only 20 amino acids. In fact, 61 of the 64 possible triplets specify particular amino acids and 3 triplets (called stop codons) designate the termination of translation. Thus, for most amino acids, there is more than one code word.

What characteristics separate algae from a) protozoans and b) plants?

Answers

a.) Algae vs Protozoans


The main difference between Protozoans and Algae is that Algae are autotrophs, meaning they make their own food. Protozoans, on the other hand, are heterotrophs, they ingest other organisms or organic molecules.


b.) Algae vs plants

One of the more striking differences between algae and plants is their complexity. Algae can either be unicellular or multicellular, while plants are multi-cellular only. Plants have vascular systems, it allows the uptake and transport of nutrients and water. Algae needs to get all of its nutrients from water. Reproduction is also another difference between them. Plants have a more complex mode of reproduction. Algae reproduces through spores and replication.

Answer:

a.) Algae vs Protozoans

The main difference between the algae and protozoa is that algae can make their own food by the help of photosynthesis and and protozoa ear the food made by autotrophs.

b.) Algae vs plants

The main difference between the algae and plants is that algae has a simple body structure sometimes they are unicellular and plants are multicellular complex kind of body organization.

During embryonic development of animals, tissue layers form. This process of embryonic tissue development is called _____. embryology morphology gastrulation germination

Answers

Gastrulation is the process in which tissue layers are developed. These layers of tissue later become organs and organ systems. Germination is a process restricted to plants while embryology and morphology are considered studies of the growth and changes in organisms.

Answers

It's probably either of Geology and Oceanography.

Geology is the study of solid earth which deals on rocks while Oceanography simply studies the ocean. For the study of deep-sea vents, it's probably more into geology while the studies of life on the deep sea is part of oceanography.
