tRNA-precursors were smaller than the modern tRNA and their primary function was to participate in the formation of new structures by joining two or more RNA molecules.
The adaptor hypothesis is the explanation of how information could be extracted from a nucleic acid into a string of amino acids in a specific sequence. The proposed explanation involved recognition between the adaptor (today tRNA) and the template nucleic acid .
Answer:
The correct answer is - stem cells.
Explanation:
Stem cells can give rise to all tissues and organs in the body. These cells can differentiate into any form of cells, which allows them to repair tissues that have been damaged by various physiological or natural ways
There are two types of stem cells: Adult Stem Cells and Embryonic stem cells.
Cells that are present in the bone marrow or umbilical cord of a newborn baby and can be divided as Hematopoietic, a cell that can form blood cells and the immune system, and mesenchymal that form the body's cartilage, bones, muscles and other.
Embryonic stem cells are found on at blastocyst stage of embryo. These cells can transform into any type of tissue in the human body, which increases their treatment potential.
Answer:
The answer is Intraspecific competition.
Explanation:
The indication of rivalry amidst organisms of the same species is called intraspecific competition.
Answer:
The 4 codons that code for Alanine are :-
GCU ; GCC ; GCA ; GCG ;;
codon for Valine :-
GUU ; GUC ; GUA ; GUG
Part A. Total number of possible mutations are 36.
GCU
GCU --> GCC , GCA , GCG
GCU --> GUU , GAU , GGU
GCU --> UCU , CCU , ACU
GCC
GCC --> GCU , GCA , GCG
GCC --> GUC , GAC , GGC
GCC --> UCC , CCC , ACC
GCA
GCA --> GCU , GCC , GCG
GCA --> GUA , GAA , GGA
GCA --> UCA , CCA , ACA
GCG
GCG --> GCU , GCC , GCA
GCG --> GUG , GAG , GGG
GCG --> UCG , CCG , ACG
Part B. Silent mutations occur when the last base of the codon is substituted with other bases.
Thus, the Total number of silent mutations are 12.
Part C. Conservative mutations occur when the second base of the codon is substituted to a "U".
Thus, the Total number of conservative mutations is 4.
