Answer:
B. Nearly every amino acid translated after the error will create the wrong protein after the deletion of a base.
Explanation:
Generally, mutations occur in two ways: 1) a base replacement, where one base is replaced for another; 2) insertion or deletion, where a base is either incorrectly inserted or deleted from a codon.
When a nucleotide is wrongly inserted or deleted from a codon, the effects of this change can be extreme. An insertion or deletion can affect every codon in a particular genetic sequence. For example, given the code:
GAU GAC UCC GCU AGG. It is the codes for the amino acids aspartate, aspartate, serine, alanine, and arginine. If the A in the GAU were to be deleted, the code would become GUG ACU CCG UAG G. It won't produce any right amino acid.
So, if the code becomes changes, it won't produce any amino acid or will produce the wrong amnio acid.
To all parts but particularly u can say phloem sap
Answer:
All of these are correct
Explanation:
According to the question, marble is a rock formed from limestone, which in turn is also formed from Calcite. This shows that marble is a kind of metamorphic rock because a metamorphic rock is any rock that is formed by the alteration of other rocks caused by heat, pressure or chemicals etc. These changes that occurs in the previously existing rocks are called METAMORPHOSIS.
Hence, since marble is formed from limestone, it concludes that marble is a metamorphosed rock formed from a previously existing limestone rock. Also, since Calcite, a precursor of limestone that marble is formed from can be degraded by acids, both limestone and marble which are formed from it will also be dissolvable by acids.
Macromolecules, hope this helps.
