How many possible codons exist in the genetic code A codon is a trinucleotide sequence of DNA or RNA that corresponds to a specific amino acid. The genetic code describes the relationship between the sequence of DNA bases (A, C, G, and T) in a gene and the corresponding protein sequence that it encodes. The cell reads the sequence of the gene in groups of three bases. There are 64 different codons: 61 specify amino acids while the remaining three are used as stop signals.

What is a codon? Explanation. What is a codon in simple terms? A codon is a trinucleotide sequence of DNA or RNA that corresponds to a specific amino acid. The genetic code describes the relationship between the sequence of DNA bases (A, C, G, and T) in a gene and the corresponding protein sequence that it encodes. The cell reads the sequence of the gene in groups of three bases. Youtube video: https://lnkd.in/dqFbuCan #nikolaysgeneticslessons

How to find a number of Amino acids in protein chain? A codon is a trinucleotide sequence of DNA or RNA that corresponds to a specific amino acid. The genetic code describes the relationship between the sequence of DNA bases \(A, C, G, and T\) in a gene and the corresponding protein sequence that it encodes. The cell reads the sequence of the gene in groups of three bases. There are 64 different codons: 61 specify amino acids while the remaining three are used as stop signals.

The Rural Life Conference (RLC) was very successful. we presented our research work on starch biosynthesis gene expression and high nighttime temperature on rice. where, starch biosynthesis is coordinated and eventual mechanism with multiple genes involvement. We quantified expression of different genes during grain filling stage of rice. We observed altered expressions of involved genes during grain fillings stage of rice.

DNase (RNase-free) is an endonuclease that digests ssDNA, dsDNA and DNA in DNA-RNA complexes. The enzyme activity is strictly dependent on Ca²⁺ and is activated by Mg²⁺ and Mn²⁺ ions. Enzyme is purified from P.pastoris(K.phaffii) expressing bovine pancreas DNAse I gene. DNAse I may be used to degrade DNA in applications that are sensitive to the presence of RNAses.

How to find if two genes are linked or not We can see if two genes are linked, and how tightly, by using data from genetic crosses to calculate the recombination frequency. By finding recombination frequencies for many gene pairs, we can make linkage maps that show the order and relative distances of the genes on the chromosome.

What is Genome Sequencing? The technique that allows researchers to read and decipher the genetic information found in the DNA of anything from bacteria to plants to animals is called genomic sequencing. Sequencing involves determining the order of bases, the nucleotide subunits (adenine, guanine, cytosine and thymine, referred to by the letters A, G, C and T) found in DNA. (Humans have about 3 billion base pairs.) Three nucleotides in a row specify one kind of amino acid, and a gene is defined by a long string of these triplets.

How to find genotype and allelic frequencies In a broad sense, the term "genotype" refers to the genetic makeup of an organism; in other words, it describes an organism's complete set of genes. In a more narrow sense, the term can be used to refer to the alleles, or variant forms of a gene, that are carried by an organism. Allele, also called allelomorph, any one of two or more genes that may occur alternatively at a given site (locus) on a chromosome. Alleles may occur in pairs, or there may be multiple alleles affecting the expression (phenotype) of a particular trait. Youtube video: https://lnkd.in/dBAdYFbJ #nikolaysgeneticslessons

Gene linkage Genetic linkage describes the way in which two genes that are located close to each other on a chromosome are often inherited together. ... In fact, the closer two genes are to one another on Youtube video: https://lnkd.in/dCwvABtb #nikolaysgeneticslessons
