Answer:
The correct answer is hybridization.
Explanation:
The procedure by which organisms of distinct species, breed, or varieties are chosen to interbred so that to generate offspring with the wanted characteristics is known as hybridization. Identically, the Maltese dogs were bred selectively so that to achieve the desired characteristics like less shedding of hairs, small size, and others.
Answer:
Bacteria are unicellular microorganisms that are not visible by the naked eye. they are found everywhere and exist in millions in population. some of them are harmful while some are essential for us like lactobacillus which helps in formation of curd.
Answer:
Glycolysis
Explanation:
Glycolysis is the first step of cellular respiration, where glucose is turned into 2 pyruvate molecules.
This step happens in all living organisms, since it does not require oxygen and also occurs in the cytoplasm, which all cells have.
So, glycolysis is the process that all organisms do during cellular respiration.
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.
The LEAF as a photosynthetic organ includes the following cells which contains CHLOROPLASTS
• the palisade mesophyll
• the spongy mesophyll and
• the stomatal guard cells
The LEAFS are the main organ of photosynthesis. Photosynthesis is the process by which green plants manufacture their food in the presence of sunlight. This takes place in the CHLOROPLASTS of these plant. CHLOROPLASTS are structures that contains chlorophyll which traps in energy from the sunlight.
The mesophyll tissues are located between the upper and the lower epidermis of the leaf. The palisade mesophyll, which is found at the upper part, contains numerous CHLOROPLASTS and is the main site of photosynthesis in the leaf.
The spongy mesophyll is located at the lower part of the epidermis. They are irregularly arranged with air spaces between them which are linked to the stomatal openings. They also contain CHLOROPLASTS.
The stomatal guard cells are a pair of bean-shaped cells which controls the opening and closing of stomata. These cells contains CHLOROPLASTS which contributes to the movement of stomata.
Therefore the three different cells of the leaf that contains CHLOROPLASTS are the palisade mesophyll, the spongy mesophyll and the stomatal guard cells.
