Answer:

anticodon.

Explanation:

anticodon, The anticodon are three consecutive nitrogen bases that are exposed. They are for the recognition of complementary nitrogen bases on the mRNA. As the three consecutive nitrogen bases on mRNA is called a codon, so, these three exposed nitrogen bases on tRNA is called the anticodon.

Answer:

Explanation:

The mRNA bases are grouped into sets of three, called codons. Each codon has a complementary set of bases, called an anticodon. Anticodons are a part of transfer RNA (tRNA) molecules. Attached to each tRNA molecule is an amino acid -- in this case, the amino acid is methionine (met).

Normally, this region is imprinted in the sperm, but not the egg. This means that the DNA on the ____________ copy of the chromo
Nostrana [21]

Answer: The DNA on the paternal copy of the chromosome will be methylated at the imprinting center, while the DNA on the maternal copy of the chromosome will not be methylated in this region.

Explanation:

Chromosomes are DNA structures associated with proteins such as histones. They are found in the nucleus of cells and contain genetic information for the development and functioning of an organism. Human beings are diploid, meaning that they possess two copies of each of the 23 chromosomes (a total of 46).

Gametes, which are sex cells such as the sperm (produced by the male) and the egg (produced by the female) that are haploid. This means that they possess only one chromosome of each pair. During fertilization, a male gamete fuses with a female gamete to generate a zygote, which will give rise to a new human being. <u>This new individual will possess half of the genetic material from its father and half from its mother. Thus having a total of 46 chromosomes, 23 from each parent</u>.

Genetic imprinting modulates gene expression by chemical modification of DNA and/or modification of chromatin structure. Often, genetic imprinting causes a gene to be expressed only on the chromosome inherited from one of the parents. One example of imprinting is DNA methylation, which is a process by which methyl groups are added to DNA. <u>Methylation modifies DNA function when found in the promoter gene, repressing gene transcription. This means that a methylated gene will not be expressed</u>, that is, it will not produce a protein encoded by that gene. So, if a region of DNA is imprinted in the sperm cell, the paternal chromosome inherited from this sperm will be methylated in the genes of the offspring. And the offspring will only express the maternal copy inherited, which will not be methylated.

Name three environmental factors that can damage the genes that produce those enzymes
igor_vitrenko [27]
The following are the environmental factors that can damage genes that code for these enzymes. radiation from sun, various chemicals and x-rays. these agents are referred to as environmental mutagens. they result to changes in the genetic make up of the organism and in  turn affect the production of enzymes. enzymes are protein in nature and once the DNA has been compromised their production is affected. in most cases mutated DNA produces enzymes with lost or abnormal function.
