Answer:
1: The mRNA would not be sythensised
Explanation:
RNA polymerase - used in transcription to initiate replication of mRNA.
If mutated then it will result to no mRNA synthesied????
The answer is C, glacial till soil. Glacial till is a mixture of coarse clay and rock particles according to the reading.
Answer:
Types of variation in genetics
Genetic variation can be caused by mutation (which can create entirely new alleles in a population), random mating, random fertilization, and recombination between homologous chromosomes during meiosis (which reshuffles alleles within an organism's offspring)
other answer
There are three sources of genetic variation: mutation, gene flow, and sexual reproduction. A mutation is simply a change in the DNA. Mutations themselves are not very common and are usually harmful to a population. Because of this, mutations are usually selected against through evolutionary processes
Answer: ecosystem
An ecosystem is a community of living and non-living components. A coral reef is an aquatic ecosystem which is formed by a continuous walls of calcium carbonates released by living animals they get combine to form rocks. These rocks and walls are collectively called as hard stony corals. These hard stony corals provide shelter to many aquatic animals like fishes. As the water is the chief abiotic factor along with coral walls and rocks which help in the survival of living organisms therefore, ecosystem is the largest organizational level found in one coral reef.
Answer: The question is incomplete,below is the complete question.
What are the terms describes the dna–protein complexes that look like beads on a string?
A) Chromatin
B) 30-nanometer fibre
C) Histones
D) Nucleosome
The correct answer is option D
Explanation: A Nucleosome is the basic fundamental unit of a DNA, and the fundamental sub-unit of a Chromatin.
The Nucleosome is the basic packing unit of DNA,it is built from histone proteins. A nucleosome is made up of 8 histones proteins resembling a thread wrapped round a spool.
The smallest bundle of DNA is known as a Nucleosome,a Nucleosome is produced through interaction between DNA and histone proteins.
