Trans fat are fats found in thinks like sticks of margarine, snack foods, baked goods, and some fried foods. Trans fats are created when vegetable oils have hydrogen atoms added to them (or hydrogenated). Trans fats can raise cholesterol and increase the risk of heart disease.
B. a specific place on a chromosome where a particular gene resides.
A locus (plural loci) in genetics is the position of a gene on a chromosome. Each chromosome carries many genes; humans' estimated 'haploid' protein coding genes are 19,000-20,000, on the 23 different chromosomes. A variant of the similar DNA sequence located at a given locus is called an allele.
Answer:
True
Explanation:
A mutation is any alteration in the genetic sequence of the genome of a particular organism. Mutations in the germline (i.e., gametes) can pass to the next generation, thereby these mutations can increase their frequency in the population if they are beneficial or 'adaptive' for the organism in the environment in which the organism lives (in this case, an insect/bug). The mutation rate can be defined as the probability of mutations in a single gene/<em>locus</em>/organism over time. Mutation rates are highly variable and they depend on the organism/cell that suffers the mutation (e.g., prokaryotic cells are more prone to suffer mutations compared to eukaryotic cells), type of mutations (e.g., point mutations, fragment deletions, etc), type of genetic sequence (e.g., mitochondrial DNA sequences are more prone to suffer mutations compared to nuclear DNA), type of cell (multicellular organisms), stage of development, etc. Thus, the mutation rate is the frequency by which a genetic sequence changes from the wild-type to a 'mutant' variant, which is often indicated as the number of mutations <em>per</em> round of replication, <em>per</em> gamete, <em>per</em> cell division, etc. In a single gene sequence, the mutation rate can be estimated as the number of <em>de novo</em> mutations per nucleotide <em>per</em> generation. For example, in humans, the mutation rate ranges from 10⁻⁴ to 10⁻⁶ <em>per </em>gene <em>per</em> generation.
Answer:
NH2 group combines with COOH group to form CONH group after releasing water
Explanation:
A peptide bond is formed between two R groups of amino acids by eliminating a molecule of water. If two amino acid joins, then a dipeptide link is formed. When three amino acid joins, then a tripeptide link is formed. And in case when many amino acid joins, then a polypeptide link is formed. A protein chain usually has several amino acid residues ranging from 50 to 2000 in numbers. Since a polypeptide chain is formed after the removal of water , it is known as amino acid residues.
Generally , NH2 group combines with COOH group to form CONH group after releasing water
