the condition of having a diploid chromosome complement in which one chromosome lacks its homologous partner.
Monosomy: the condition of having a diploid chromosome complement in which one chromosome lacks its homologous partner.
A trisomy is a chromosomal disorder characterized by an additional chromosome, so the person has 47 instead of 46.
Nullisomic is a genetic condition involving the lack of both the normal chromosomal pairs for a species (2n-2).
So, the correct answer is 'Monosomy'.

In the experiment by Nirenberg and Matthaei described in the animation, why does it make biological sense that the U2 oligonucleotide showed such poor ability to bind to ribosomes and tRNA charged with phenylalanine
We have that for the Question "In the experiment by Nirenberg and Matthaei described in the animation, why does it make biological sense that the U2 oligonucleotide showed such poor ability to bind to ribosomes and tRNA charged with phenylalanine"
Answer:
This is because, the genetic code could not involve a two-base codon because such a system would not provide enough unique codons to cover all 20 amino acids.

How many seconds would it take DNA polymerase to replicate one set of human chromosomes (6,000,000,000 bytes long)
The typical human chromosome has about 150 million base pairs that the cell replicates at the rate of 50 pairs per second.
What is chromosome ?A chromosome is a thread-like structure present in the nucleus of cells such as plant, animal and human cells and it is made of a molecule of DNA (Deoxyribonucleic acid) and histone proteins.
It is composed of three components, DNA, proteins and RNA, amount of the DNA content ranges from 30 to 40 %, the amount of proteins from 50 to 65%, and small amount of RNA from 1 to 10%.
Two types of protein present in DNA such as histone and non-histones proteins, histone constitute large amount (90% of total protein), whereas non-histone is present in small amount (around 10% of total protein).
The histone protein is basic, whereas, the DNA is acidic, so it can be neutralized; DNA in chromosome is present in two forms such as Euchromatin and Heterochromatin.

To maintain homeostasis, ADH functions via a ______ feedback mechanism that responds to blood ______ concentration.
Answer:
negative, salt
Explanation:
ADH functions via a negative feedback mechanism that responds to blood salt concentration to maintain homeostasis.
What is homeostasis?In order to maintain a constant state between internal conditions and the external environment, a cell's response to its environment is known as homeostasis.
Because of their complexity and uniqueness to living things, the coordinated physiological responses that keep the majority of the body's dynamic equilibrium in place have been given the name "homeostasis."
Ex: When it's cold outside, we start to shiver and use energy to stabilize our body temperature. This is where the cell regulates cell temperature, fluid balance, sugar balance, etc. through it.
Therefore, there is negative feedback that responds to blood salt concentration.

In eukaryotic mRNA, the parts that remain after processing and are translated into amino acid sequences are called the _____.
Answer:
Exons.
Explanation:
In mRNA maturation and processing, a complex called a splicesome essentially "cuts out", if you will, non-coding parts of the DNA sequence to be translated. The parts that are cut out are called "introns", and the parts that are left over that code for a protein sequence, are called "exons". Careful with the terminology. It seems counterintuitive that exons are the ones that stay (exon = exit? NO.) and introns (in, as in, stays in? NO.) are the ones that are cut out of the mature mRNA. Perhaps you can remember that the terms seem to be the opposite, that's how I remember it. Alright, good luck with all of this.
