A gene is the basic physical and functional unit of heredity. Genes are made up of DNA. Some genes act as instructions to make molecules called proteins. However, many genes do not code for proteins. In humans, genes vary in size from a few hundred DNA bases to more than 2 million bases. The Human Genome Project estimated that humans have between 20,000 and 25,000 genes.
I think it is called crust which is outermost layer of planet or satellite.
Glycine glycine - Silent mutation. Lysine stop; - Nonsense mutations. Silent mutations are caused by a point mutation and have no effect of the function because they code for the same amino acid. Missense mutations are caused by a point mutation and result in a different amino acid to be placed in the protein. Nonsense mutations is caused by a point mutation and cause a stop where there should not be one. The Frame shift mutations on the other hand are caused by insertion or deletion of a nucleotide causing a reading frame to shift and the protein to be too long or too short.
Answer:
Step 1: Write out your key in terms of what's dominant and recessive. Step 2: Determine the genotypes of the parents and write out the cross. Step 3: Figure out what kinds of gametes each parent can produce. Step 4: Set up a Punnett square for your mating.
Explanation:please give brainliest
Monocots<span> have distinct structural features. L<span>eaf veins of the monocots are parallel. Flower parts are in multiples of three per whorl. Stems have no pith region. Other characteristics of monocots are: its embryo is with a single cotyledon and its pollen is with single pore. </span></span>
