Why did geneticists believe, even before direct experimental evidence was obtained, that the genetic code would turn out to be composed of triplet sequences and be non overlapping

Answers

Answer: this is because with triplet sequences, diversities would be generated and the possibility of overlapping is minimal

Explanation:

Answer:

Geneticists believe, even before direct experimental evidence was obtained, that the genetic code would turn out to be composed of triplet sequences and be non overlapping because a triplet code gives 64 possible combinations but we only have 20 essential amino acids in our human proteins so there's room for some redundancy. That way some point mutations will still be able to correctly code for the desired protein.

Explanation:

The Genetic Code would turn out to be composed of triplet sequences means that 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 of "letters of the alphabet,"  that are used to write the "code words."

The genetic code consists of a sequence of three letter "words," (sometimes called 'triplets', sometimes called 'codons'), written one after another along the length of the DNA strand.

Each code word is a unique combination of three letters (like the ones shown below in the attachment) that will eventually be interpreted as a single amino acid in a polypeptide chain. There are 64 code words possible from an 'alphabet' of four letters.

One of these code words, the 'start signal' begins all the sequences that code for amino acid chains. Three of these code words act as 'stop signals' that indicate that the message is over. All the other sequences code for specific amino acids.

However, some amino acids are only coded for by a single 'word,' while some others are coded for by up to four 'words.' The genetic code is redundant.

Genetic codes do not overlap: The genetic code is composed of nucleotide triplets. In other words, three nucleotides in mRNA (a codon) specify one amino acid in a protein. The code is non-overlapping. This means that successive triplets are read in order.

Which characteristic do euglenoids and algae share

Answers

Euglenoids are unicellular protists commonly found in fresh water.They don not have a cell wall, despite that, a protein rich cell membrane called pellicle is present in Euglenoids.
Whereas,Algae are eukaryotic organisms comprising of no roots, stems, or leaves but they filled with chlorophyll and other pigments to carry out the process of photosynthesis. Similar to Euglenoids, they occur most frequently in water, specifically in plankton.
Hence,
Euglenoids and algae share a common characteristic,that is both are autotrophs. They produce complex organic compounds from simple substances present in their surroundings, by the use of energy from sun-light or inorganic chemical reactions.

Explanation: I took the test

On occasion, leukemia or lymphoma is discovered in abnormal results of routine blood tests. For example, above-normal white blood cell counts (leukocytosis) can be caused by immune cancers. Other immune cancers are diagnosed by abnormally high levels of antibodies in the blood. The antibody is usually of just one type, indicating that a single cell is dividing uncontrollably and secreting this antibody. What type of immune cell is the likely source of this antibody

Answers

Answer:

The serious cell: The plasmacyst or

Explanation:

The plasmacyst is a lymphocytic cell, since the plasmacyst is the maturation of the B lymphocyte.

This cell manufactures antibodies such as immunoglobulins and if it suffers metaplasia or malignancy these will be secreted in equal or greater quantity.

A lot of echinoderms are named after flowers true or false

Answers

Answer:

False, it is only represented by one class: Crinoidea (sea lilies).

Explanation:

Echinoderms (phylum Echinodermata) are marine organisms that comprises more than 6,000 species. These animals are deuterostomes that are differentiated to have an ambulacral  vascular system and a pentameric symmetry. Echinoderms are divided in the following classes: 1- Ophiuroidea (snake stars), 2-Asteroidea (sea stars), 3-Crinoidea (sea lilies), 4-Holothuroidea (sea cucumbers) and 5-Echinoidea (sea urchins), which can be easily distinguished  by anatomical and ecological characteristics.

In chickens, comb shape is determined by alleles at two loci (R, r and P, p). A walnut comb is produced when at least one dominant allele R is present at one locus and at least one dominant allele P is present at a second locus (genotype R_ P_). A rose comb is produced when at least one dominant allele is present at the first locus and two recessive alleles are present at the second locus (genotype R_ pp). A pea comb is produced when two recessive alleles are present at the first locus and at least one dominant allele is present at the second (genotype rr P_). If two recessive alleles are present at the first and at the second locus (rr pp), a single comb is produced. A walnut is crossed with a pea chicken and the offspring consists of 3/8 walnut, 3/8 pea, 1/8 rose and 1/8 single. What are the probable genotypes of the parents

Answers

Answer:

RpPp x RpPp

Explanation:

For the recessive trait to be expressed, both parents should have at least 1 allele for the recessive trait. Now you can see that both recessive traits were expressed in at least one of the off-springs, this means that both parents had the allele for each recessive trait.
